HOW TO USE THIS MANUAL

The role of Quick Start and the complete guide

If your goal is simply to make your first connection as quickly as possible, start with the Getting Started Guide. That page keeps to the shortest practical path and explains only what you need for each step. This guide goes further, covering why each choice matters, platform-specific import differences, why a connection may appear successful but still fail to work as expected, and how to handle device changes, plan adjustments, and subscription maintenance.

For your first setup, we recommend reading from the beginning in order. If you already have a working connection, jump straight to route selection, connection verification, or routine maintenance. For service details and pricing, refer to the Plans page and the information currently shown in your user panel. For regions and route types, keep the Route List open for comparison.

SERVICE MODEL

Understand the cross-border network acceleration service

What subscriptions, clients, and routes each do

Before you begin, separate the subscription service into three related but distinct parts. VPNFB provides the account, plan, subscription information, and route resources; the client reads the subscription and establishes a connection on your device; the route determines the region of your current exit point and the network path used to reach a target service. Many first-time questions come from treating these three parts as the same thing. Installing a client does not mean the subscription has been imported. Importing a subscription does not mean the selected route is suitable for the target website. Even a connected status alone cannot prove that browser or app traffic is following the selected route as expected.

Think of a subscription as the client’s entry point for reading route configuration. It is not an ordinary bookmarked webpage and should not be shared publicly. The client uses it to retrieve the routes available to your account, after which you choose a route and start the connection. Route information may change as the service is managed, so long-term use is less about preserving one old configuration and more about keeping access to your user panel and letting the client refresh the subscription regularly. When switching devices, retrieve the subscription again from your own user panel instead of copying old content from chat history, screenshots, or unknown sources.

How coverage relates to real-world performance

VPNFB covers 100+ countries and 230+ routes. Coverage indicates the range of regions and paths available, but it does not mean every user will have exactly the same experience on every network. Performance also depends on the current access network, your location, the target service, route distance, peak-time congestion, and client status. A better way to choose a route is to define the goal first: reliable everyday browsing, AI tools, streaming, or a service tied to a particular region. Then start with a nearby region and judge the result through actual access, rather than focusing only on route names or a single client status.

Route distance often affects response time, but it is not the only factor. A geographically close route may follow a poor path on the current network, while a slightly farther relay route may be more stable. Compare routes using the same device, access network, and target service; avoid direct comparisons across different environments. Rapidly switching networks, routes, and client settings makes the cause harder to identify. A safer method is to change one variable at a time: keep the device and network fixed, then try another route. If the problem remains, check the client or target service.

How monthly subscriptions and data packages work

The service offers monthly subscriptions and data packages. Monthly plans are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB; traffic resets monthly on the activation date. When upgrading mid-cycle, the price difference is prorated over the remaining days. Data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB; they last until used and never expire. The main difference is how traffic is managed, not the route names. Monthly subscriptions suit steady use with a fixed monthly allowance, while data packages suit irregular usage when you want unused traffic to remain available.

“Unlimited devices” means the account is not capped at a fixed number of devices, but traffic from every device still counts against the relevant plan. When importing the subscription on home computers, personal devices, and work devices at the same time, monitor total usage and avoid sharing the subscription with unrelated people. The more devices you use, the more important clear management becomes: know which devices remain active, which clients enable auto-connect, and which systems may be syncing large amounts of data in the background. If usage changes unexpectedly, check background tasks on each device before changing the subscription.

PLAN SELECTION

Choose a plan by usage pattern

Estimate your needs first instead of defaulting to the largest allowance

The key to choosing a plan is your usage pattern, not automatically picking the highest price or largest allowance. Text websites, email, research, and occasional AI tools usually consume traffic differently from long video sessions, large file syncing, or continuous background transfers across multiple devices. Before deciding, list the devices, main apps, and usage frequency involved, then determine whether you need steady monthly use or occasional bursts. Because the available facts do not assign fixed traffic consumption to individual apps, this guide does not offer seemingly precise conversion figures that may not apply to everyone.

The three monthly plans are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB. All reset traffic monthly on the activation date. Pay close attention to “reset on the activation date”: the cycle follows your actual activation date rather than placing every user on the calendar-month boundary. Check the current cycle in your user panel instead of guessing from the calendar. If you upgrade mid-cycle, the price difference is prorated over the remaining days, so use the panel result rather than calculating a full month yourself.

Choosing between a monthly subscription and a never-expiring data package

The three data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. They last until used and never expire. They suit irregular usage: you may handle cross-border tasks intensively at times and remain inactive for longer periods while keeping unused traffic available. Monthly subscriptions are better for steady everyday use because each cycle provides its corresponding allowance. Do not compare the two by total volume alone; also consider whether you need continuous access, can work with monthly resets, and how much your traffic varies.

If you are unsure, start with the plan that covers your clearly identified needs and adjust it later using actual usage records in the panel. Do not over-choose because you might use more in the future, and do not underestimate consumption when background sync, system updates, or high-traffic apps are running. VPNFB supports unlimited devices, so one account can cover more devices, but those devices may also generate traffic together. Choose based on total account usage, not only your primary device.

Product type Price and allowance Traffic rules Best usage pattern
Monthly subscription ¥9.9/month with 60GB Resets monthly on the activation date Steady, light use
Monthly subscription ¥18/month with 250GB Resets monthly on the activation date Steady, multi-purpose use
Monthly subscription ¥28/month with 500GB Resets monthly on the activation date Steady, high-volume use
Data package ¥158/300GB Lasts until used; never expires Occasional use
Data package ¥358/1000GB Lasts until used; never expires Occasional use across multiple devices
Data package ¥658/3000GB Lasts until used; never expires Long-term retention and concentrated use

Refund policy and pre-payment checks

VPNFB offers a 7-day no-questions-asked refund. Before paying, verify the plan name, product type, allowance, and account so you do not confuse a monthly subscription with a data package. Alipay, WeChat Pay, and USDT are supported. During payment, confirm the order and payment status only in the user panel. Do not recreate an order through an unfamiliar page or submit repeatedly because a page responds slowly. If the status does not change promptly after payment, keep the current order page, refresh your account information, and use the user panel’s ticket entry.

The plans page provides the central pricing details; this guide focuses on how to choose. Before ordering, open the Plans page and check each item again. In particular, monthly subscription traffic resets each month on the activation date, while data packages never expire. When upgrading mid-cycle, the price difference is prorated over the remaining days. Understanding these rules in advance helps avoid mistakes caused by different expectations about billing cycles.

ACCOUNT AND ORDER

Complete account setup and ordering with payment confirmation

Create an account you can manage over time

VPNFB registration requires no email address; a username and password are enough. Choose a username that is easy for you to recognize, but do not make it identical to a public social account or another important account. Store the password separately and never reuse it elsewhere. Since no email address is required, account recovery cannot rely on the usual email process. After creating the account, save the username, password, and order details immediately in a reliable password manager. Do not rely only on temporary browser memory or keep complete credentials in a chat or document visible to multiple people.

When entering the user panel from this page, use the First Month Free entry to open the account creation view. After entering a username and password, check that your input method has not inserted spaces and that your password manager has not filled credentials from another site. Once the account is created, stay on the page and open the account overview to verify the username and plan status. If the page remains on the authentication view, do not create multiple usernames in succession. First try signing in with the credentials you just saved, and check whether the browser is blocking required site storage.

Final checks before creating an order

In the plans section, first distinguish monthly subscriptions from data packages, then select the specific tier. Monthly subscriptions are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB; data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. The order confirmation page should show the product name, price, and payment method you intend to use. If anything differs from your expectation, return to the plan list and choose again instead of paying first and trying to modify the order later.

Payment is supported through Alipay, WeChat Pay, and USDT. Choose a method you can complete reliably and verify afterward. Do not close the original order page during payment or create duplicate orders for the same product in multiple tabs. After paying, return to the user panel, wait for the order status to update, and reload the account overview. The browser back button may only return to the previous page and may not refresh the order, so rely on the order list and plan status in the user panel.

What to do when the order status does not update

Payment and account activation are adjacent but separate steps. Even when the payment page shows completion, the account status may need to reload. Keep the network stable, return to the panel, and refresh the order section. If several panel tabs are open, keep one and close the rest so an old page does not distort your judgment. Do not pay again before confirming the original order result. Duplicate orders only make verification harder; they do not update the original status faster.

If the plan still does not appear after refreshing, open the ticket section in the user panel and provide your username, order record, and the transaction details that identify this payment channel. State clearly that the payment is complete but the plan status has not updated, and include the order status currently shown in the panel. Never submit a password or complete subscription publicly. The goal of a ticket is to connect the account, order, and payment result, so a clear status description is more useful than repeated follow-ups.

Login state and browser environment

The user panel uses the browser to retain your login state. Clearing site data, using private browsing, or switching browsers may require you to sign in again. This does not mean the plan has disappeared: the plan is linked to the account, not stored only in the current browser. When changing devices, use the original username and password to enter the panel and view your account and subscription. If the panel shows a new-account state after login, first check the username, especially capitalization, similar characters, and spaces inserted by the input method.

After making a purchase on a shared device, sign out of the user panel and clear the autofill information saved by the browser for this site. On a personal long-term device, you can use a password manager to store credentials, but keep an independent backup as well. Better account management makes future client changes, subscription recovery, and order handling smoother. Not requiring an email address simplifies registration, but it also makes careful storage of your login credentials especially important.

SUBSCRIPTION DELIVERY

Get and protect your subscription information

Retrieve the subscription from your user panel

After the plan is activated, open the account overview or client section in the user panel to retrieve the subscription. Copy it from the account you are currently signed in to; do not use an address found in search results, forum posts, or forwarded by someone else. The panel may provide both a client entry and subscription controls: the client installs the connection tool, while the subscription imports the routes available to your account. They work together but cannot replace each other. Users who have already installed a client still need to import the subscription, while users who have copied it still need to load it in a supported platform client.

Make sure the entire content is copied. Browsers and chat tools may truncate long addresses, and an ellipsis shown on screen is not part of the subscription. The safest method is to use the copy control in the panel and switch directly to the client to paste it. If you need temporary storage, use a protected password manager rather than a public note. An example subscription address can look like the one below, but for real use you must retrieve it from your own panel and never use the example value.

https://example.com/sub?token=YOUR_TOKEN

Why your subscription should be handled like a password

A subscription lets a compatible client read the route configuration linked to your account, so it should not be shared publicly. Before taking screenshots, check whether the complete subscription is visible; when recording a walkthrough, hide it as well. Sending the subscription to unmanaged devices makes traffic sources harder to identify and may cause unexpected plan usage. Even though VPNFB does not limit the number of devices, that does not make a subscription suitable for unrestricted distribution. Unlimited devices is intended for one user’s multiple devices, and responsible management is still necessary.

If you suspect that the subscription has been exposed, open the user panel and check for a reset or update option, then re-import the updated subscription on your devices. Delete the corresponding configuration or uninstall the client from devices you no longer use. After updating the subscription, confirm on each device that the new version can be read before removing old content. Do not make several changes on every device at once; if one device then fails to connect, it becomes difficult to tell whether the issue is the subscription, client, or route.

The difference between importing and updating a subscription

The first import lets the client recognize the set of routes associated with your account. Updating refreshes route information on top of an existing configuration. Seeing old route names in the client does not mean the subscription is current. If the route list clearly differs from the Route List page, some routes remain unavailable for a long time, or the panel has recovered while the client still shows an old state, update the subscription first and then decide whether a fresh import is needed.

Before updating, note the route currently in use so you can select the same region or a suitable new route afterward. Some clients retain the old selection after an update, while others return to a default route, so check actively when the update finishes. If the update fails, confirm that the account plan remains valid, the device can reach the user panel, and the copied content is complete. Then try deleting the old subscription in the client and importing it again. Before deleting anything, make sure the username, password, and panel entry are still available.

Managing multiple devices

Windows, macOS, iOS, Android, and Linux can all use the service through their corresponding clients. Give each device a clear name, such as one based on its platform and purpose, instead of leaving indistinguishable default names in every client. Although the account supports unlimited devices, different devices may generate traffic at the same time. Disable auto-connect and background syncing on devices that sit idle for long periods, and delete the subscription when a device is retired so you do not later forget it exists.

When adding a device, start in the client download section of the user panel, then copy the subscription from the panel. Do not export a complete configuration containing unrelated settings from an old device and overwrite the new one, because system networking, proxy modes, and app permissions may differ. Migrating only the subscription entry and confirming the connection mode again on the new device usually keeps the setup clearer. After migration, follow the verification chapter to check the exit point and app traffic; seeing a route list in the client alone is not a completion check.

CLIENT IMPORT

Import clients on five major platforms

The common workflow across all platforms

The five platforms have different interfaces, but the import logic is the same: retrieve a client suited to your platform from the user panel, sign in and copy the subscription, find “Add subscription,” “Import from link,” or a similar option in the client, paste the complete content, wait for the route list to load, select a route, and connect. Do not close the client immediately afterward. Check the connection status first, then open a browser and visit a test page. If the client requests system network access, confirm that the request comes from the newly installed VPNFB client and follow the system prompts.

When an import fails, first distinguish between “cannot paste,” “cannot read the subscription,” “read successfully but no routes appear,” and “routes appear but cannot connect.” Pasting problems usually involve clipboard permissions or copied content. Reading problems require checking the account and current network. An empty route list may indicate that the subscription is not updated. If routes appear but cannot connect, move to the route and connection sections. Blaming every issue on installation leads to unnecessary repeated uninstalls.

Platform Key checks before import Key checks after connection Access point
Windows Confirm system network permissions and the active network Check system proxy settings and browser access Client download section in the user panel
macOS Confirm system extension and network configuration permissions Check menu bar status and app traffic Client download section in the user panel
iOS Confirm the prompt to add a network configuration Check system status and the target app Client download section in the user panel
Android Allow the system connection to be created Check background restrictions and power-saving policies Client download section in the user panel
Linux Confirm configuration permissions and the runtime environment Use the command line to verify resolution and requests Client download section in the user panel

Windows: confirm the active network first, then import the subscription

On Windows, get the client from the client download section of the user panel. After installation, confirm that the network connection currently in use is working, then open the client and import the subscription. If the device is connected to both wired and wireless networks, identify which one is active so the path does not change during testing. After pasting the subscription, wait for the full route list to appear, select the target region, and connect. When Windows shows a network access or security prompt, verify the app name and allow the required permission.

After connecting, use a browser to visit an ordinary webpage before checking the target service. If the client says it is connected but the browser cannot access pages, check whether another network tool changed the system proxy and whether the browser uses an independent proxy extension. Closing other similar tools before reconnecting can reduce configuration conflicts. Before exiting the client, use its in-app disconnect control rather than terminating the process; a normal disconnect helps the system restore its previous network state.

macOS: handle system permissions and conflicts with old configurations

When running a client for the first time on macOS, the system may ask you to add a network configuration or approve related permissions. Open the relevant settings from the system prompt, complete authorization, and return to the client. If you have used another network tool, disconnect it before importing the VPNFB subscription. When multiple tools control the system network at once, the menu bar may show a connected state while the actual traffic path remains unclear. Keeping only one connection tool active at a time makes verification easier.

After importing the subscription, select a route, connect, and observe the system status. If a connection still cannot be established after authorization, quit and reopen the client, then check whether disabled old network configurations remain in system settings. Do not delete unfamiliar corporate or work configurations without reason. If the device is managed by an organization, confirm that its policy permits adding a new connection. On a personal device, you can remove configurations clearly belonging to an old client that you no longer use.

iOS and Android: focus on system permissions and background policies

On iOS, use the user panel to access the client download process. During the first connection, the system asks you to confirm adding a network configuration. Return to the client, import the subscription, choose a route, and connect. After switching between Wi-Fi and mobile data, verify the connection again because the change in network environment may require the session to be rebuilt. If the target app still shows old regional content, fully quit and reopen it, then check whether it has cached the previous network state.

On Android, the key points are system connection permission and background restrictions. After importing the subscription, allow the client to create a system connection. Some systems limit long-running apps through battery-saving or background management, causing the connection to drop after the screen locks or requiring reconnection after switching apps. Check the VPNFB client’s background-running permission in system app settings and adjust it to suit your needs. Do not disable every security setting to investigate one problem; change only items directly related to the client’s operation.

Linux: verify with a clear configuration path and commands

Linux environments vary widely, so first obtain a client and instructions suited to your environment from the user panel rather than assembling installation steps from an unknown software source. After importing the subscription, confirm that the client can read the routes and start a connection in the current desktop session or command-line environment. With a graphical interface, check the system tray status. With command-line use, keep the terminal output so you can see how far subscription reading, connection setup, and network requests have progressed.

After connecting, you can use basic commands without sensitive information to check DNS resolution and web requests. The examples below access only example domains and contain no real subscription or account details. If the resolution command succeeds but the web request fails, the issue may be in the connection path or app settings. If the domain cannot be resolved, check the local DNS and current network first. When troubleshooting is complete, close the test terminal and avoid publicly sharing output that contains environment details.

ROUTE SELECTION

Route selection and connection assessment

Choose a region based on the target service first

Choose routes based on the target service, not the route name. For everyday browsing and research, start with a region relatively close to your current network. If the target service has a specific regional requirement, choose a route matching that region. With AI tools, look beyond whether the connection is established and check whether login remains stable and page requests continue to succeed. Streaming depends more heavily on how the service identifies the exit region, and you may need to reopen the app after connecting to clear its old session state.

VPNFB provides 100+ countries and 230+ routes. See the complete regional list in the Route List. Broad coverage is useful because it provides alternative paths, not because you need to cycle through every route. A more efficient approach is to keep a small set of verified routes for common situations: one for everyday use, one for region-specific services, and same-region or nearby alternatives for periods of network instability.

Understanding the focus of direct, relay, and IEPL routes

The route page may organize routes as direct, relay, IEPL, and other types. Direct routes have a relatively straightforward structure, but their performance depends more on the current access network and cross-border path. Relay routes use traffic scheduling to improve connectivity in some network environments. IEPL emphasizes a particular link arrangement. Type names help explain the path; they are not an absolute ranking independent of context. The same route type can perform differently across regions, networks, and times.

When choosing, start with a relay or IEPL route suited to the target region, then compare it with other routes in that region. If a route connects but the target service responds inconsistently, try another type in the same region before jumping across several regions. This helps show whether the problem is tied to a specific path or to the target region itself. If no route connects, return to the subscription, client permissions, and local network layers.

Route type What to assess Recommended troubleshooting approach Metrics not to rely on alone
Direct The path between the current access network and destination region Keep the region fixed and retest with another access network Judging speed from the name alone
Relay Path scheduling and sustained connection performance Compare different routes in the same region Looking only at the client’s momentary status
IEPL Specific link characteristics and target-service compatibility Verify the exit point and app traffic after connecting Treating route types as an absolute ranking

Handling peak hours and network changes

Peak-hour performance depends not only on server-side routes but also on local broadband, Wi-Fi quality, and congestion at the regional exit. If the same route changes performance over time, first check whether ordinary webpages also load slowly, videos buffer, or packets are being lost on the local network. Disconnect the acceleration connection and access a familiar local service for comparison, then reconnect to the same route. If the local network is normal but the target service remains unstable, switch to another route in the same region.

After a device switches from Wi-Fi to another access network, the old connection may appear active even though the session has actually expired. Disconnect and reconnect deliberately instead of waiting for the app to recover. Mobile devices may show the same behavior after waking from sleep. Building the habit of reconnecting and verifying after a network change is more reliable than repeatedly refreshing the target app. If the connection often drops after the screen locks, return to the platform chapter and check background restrictions.

Build a repeatable route-selection process for common scenarios

The key to consistent route selection is repeatability. During testing, keep the device, access network, and target website fixed and change only one route. After connecting, confirm the exit region before performing the real task. Do not change client mode, browser extensions, DNS settings, and routes at the same time; even if the issue disappears, you will not know which change helped. Record the regions and route types that work for you, but do not preserve unverified speed claims.

For a systematic approach to assessing stability, see Most Stable VPN Recommendations: A Hands-on Comparison of Connection and Drop Rates. These articles cover specific scenarios; this guide remains focused on the general connection workflow.

CONNECTION VERIFICATION

Connection verification and fault isolation

Connected does not mean every flow is covered

A client’s “Connected” status usually means only that the connection reached the state recognized by the client. It does not by itself prove that browser traffic, target-app traffic, and DNS requests are following the current route as expected. Complete verification covers three layers: exit IP, DNS resolution, and the actual app. Record the exit information before connecting, reconnect through the route and query it again, then check whether the target website works. Finally, perform a real action in the app, such as signing in, loading content, or playing media.

Use a fresh browser page during verification and fully close and reopen the target app when needed. Some websites cache region data, login sessions, or old connection results, so a simple refresh may still show previous content. Do not infer the exit region from page language alone; language may come from account preferences or browser settings. For a more complete self-check, read How to Confirm a VPN Is Working: Check Exit IP, DNS, and Individual Apps.

Verifying exit IP, DNS, and individual apps

Exit IP verification confirms which network exit sends web requests. If the result changes as expected before and after connecting, browser traffic used the current path at least during the query. DNS verification checks whether domain resolution is still using an unexpected old setting. Per-app verification checks whether different programs follow the same system connection. Some apps use independent proxy settings, some browsers have network extensions, and some tools retain old environment variables, so behavior can differ on the same device.

If the browser works but one app does not, check that app’s own settings before reinstalling the client. If every app fails, check the system connection, subscription refresh, and route. If only domain access fails while direct network connectivity works, inspect DNS. If the target website opens but login repeatedly fails, the cause may be session caching, the exit region, or the target service itself. Separating failures by layer prevents every problem from being labeled as an “unstable route.”

Branch-based troubleshooting for common problems

For an empty route list, first confirm that the plan is valid, the subscription is complete, and the client has refreshed it. If routes appear but cannot connect, try another route in the same region, then check system permissions and other network tools. If the client connects but webpages do not open, disable other proxy extensions, confirm that the system network still works, and check DNS. If webpages work but the target app does not, inspect app cache, independent network settings, and account-region status.

If the problem occurs only on one access network, compare it with another network you can use. The goal is not to permanently work around the issue, but to determine whether the fault is local access, the client, or the remote route. Keep the device and route fixed while changing only the access network. If the problem follows the access network, check the local environment first. If it is identical on different networks, continue with the client and subscription.

Visible symptom Check first Next step
Subscription cannot be read Account plan, subscription integrity, current network Copy again from the user panel and re-import
Route list is empty Subscription refresh status Refresh or re-import the subscription
Route cannot connect System permissions, route, and other network tools Switch to a route in the same region and remove conflicts
Client connected but webpages fail System proxy, browser extensions, DNS Verify the exit point and resolution layer by layer
Only a specific app fails The app’s independent settings and cache Restart the app and check its traffic path

When to submit a support ticket

If the issue remains after checking the account, subscription, client permissions, local network, and same-region routes, submit a ticket through the user panel. Include the platform, selected region, stage where the problem occurs, troubleshooting steps already completed, and necessary screenshots of the error. Hide your username, subscription, and other sensitive content before taking screenshots. Do not write only “it does not work,” because that does not distinguish subscription reading, connection setup, and target-app failure.

For timing, use relative context such as “after completing payment,” “after refreshing the subscription,” or “after switching networks”; there is no need to invent precise monitoring data. Support staff need a reproducible path: which platform client you opened, whether the subscription was read, whether routes appeared, what you saw after clicking Connect, and how ordinary webpages and the target app behaved. The more structured the information, the easier it is to locate the problem at the right layer.

MAINTENANCE AND ADVANCED USE

Routine maintenance, renewals, and advanced use

Build a simple, consistent maintenance routine

Long-term use does not require constant adjustments. More effective maintenance means keeping the client source clear, ensuring the subscription can refresh, retaining a few verified routes, and checking account traffic and plan status regularly. When the client works normally, there is no need to reinstall it whenever a new route name appears. When route access fails, do not immediately wipe the entire configuration. Refresh the subscription first, try an alternative route in the same region, and only then consider re-importing or reinstalling.

After an operating-system update, a change in network environment, or a reset of client permissions, repeat connection verification. This is especially important after changing battery-saving policies on mobile devices, installing another network tool on a desktop, or adding a proxy extension to a browser, because the existing traffic path may change. Maintenance notes can remain simple: record the platforms and regions you use, the plan type, and the steps from your latest successful verification, but never record the complete subscription.

Monitoring traffic and handling unexpected usage

Monthly subscription traffic resets each month on the activation date, while data packages last until used and never expire. Interpret traffic changes according to the product type. When an account is shared across devices, system updates, cloud syncing, video playback, and background downloads may all contribute. If usage is higher than expected, inspect high-traffic tasks on each device, disable unnecessary automatic syncing, and then watch the panel for changes.

VPNFB supports unlimited devices, but device management still needs clear boundaries. Delete the subscription from devices that are no longer used, and sign out of the account and remove client configuration before retiring a device. If you cannot tell whether an old device is still active, update the subscription and re-import it on the devices you retain. Do not send the complete subscription to multiple people for shared storage; it makes traffic sources harder to identify and weakens account security.

Renewals, upgrades, and switching products

Before renewing, confirm the current product type and remaining traffic. Monthly subscriptions are ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB; data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. When upgrading a monthly subscription mid-cycle, the price difference is prorated over the remaining days, so do not calculate the result using a full cycle. After upgrading, rely on the plan status shown in the user panel.

When switching from a monthly subscription to a data package, or from a data package to a monthly subscription, first confirm that your usage pattern has changed. Steady monthly use usually prioritizes a recurring allowance, while occasional use prioritizes retaining unused traffic. Check the order type and price again before payment, then wait for the panel to update. If the status does not change promptly, follow the order principles above: do not pay again, and submit the original order details through a ticket.

Advanced traffic routing and app isolation

Some clients support deciding traffic paths by app or destination. Before using these features, make sure basic global connectivity has passed verification. Adding complex rules while the base connection is unstable makes the cause harder to isolate. A safer order is: confirm the subscription and route work, confirm that the browser and target app connect, and only then add app routing gradually. Recheck every affected app after adding each rule.

The goal of traffic routing is to send apps that need an international path through the selected route while keeping local services on a suitable access path. Build rules around real needs, and do not import oversized configurations from unknown sources that you cannot understand. If you cannot explain what a rule does, maintaining it after service changes will be difficult. For most users, a small set of clear rules is usually more reliable than a massive rule set.

Switching devices and restoring access

When changing devices, first confirm on the old device that the username and password are stored securely, then sign in to the user panel from the new device. Get the client for the relevant platform from the client download section, copy the subscription from the panel, and import it. After connecting, verify the exit point, DNS, and individual apps. Once the new device works, sign out on the old device and delete the subscription. This order prevents you from losing the original access path before the new device is ready.

If the old device is no longer usable, you can restore access on a new device as long as you still have the correct username and password. Since registration does not require an email address, protecting these credentials is especially important. If you cannot confirm the username or password, use the existing support entry in the user panel rather than trying to recover the subscription from an unknown source. After recovery, create a fresh credential backup and device list.

Turn the guide into your own operating procedure

The complete workflow can be reduced to one reliable chain: understand the product types, choose a plan that matches your usage pattern, create and protect the account, complete payment and confirm the status, retrieve the client and subscription from the panel, import them on the relevant platform, choose a route based on the target service, verify the exit point, DNS, and apps, then maintain traffic and devices. When something goes wrong, locate it within this chain instead of reinstalling everything from scratch.
