Subscription & connection issues

No email address is required. Create an account with a username and password. Open the account panel and follow the on-screen instructions, then store your login details securely. Use a password manager and avoid reusing passwords from other sites. Since an email address isn't required to create an account, don't assume email recovery will be available, and don't rely on temporary browser storage. After logging in, you can view your account, plan and subscription details in the panel. If you can't access your account, contact support through a panel ticket and share information that can help verify it. Never share your password, full subscription link or sensitive payment details in public comments or chat screenshots.

There’s no device limit. You don’t need to choose a new plan just because you’re switching devices. Log in to the panel on your new device, download the client for its operating system, and import your subscription. Windows / macOS / iOS / Android / Linux are supported; follow the panel instructions for installation and import steps. Client interfaces vary by device, so configuration steps for one platform may not apply to another. All devices on the same account share the plan’s data allowance—unlimited devices doesn’t mean unlimited data. Before handing an old device to someone else, remove the subscription and any saved login details from the client.

First, log in to the panel and check your current subscription. In your client, open subscription or profile management, select the F4VPN subscription, and update it. Afterward, make sure the active profile comes from that subscription rather than an older local copy. If needed, select a route again and reconnect. If the update fails, confirm that the device can access the panel and that you copied the entire subscription link without extra spaces or missing characters. Then reimport it as instructed by the panel. Avoid keeping multiple profiles with indistinguishable names. When contacting support, include the client, operating system, update message and circumstances—but never post your full subscription link publicly.

Treat your subscription link like an account credential. Don’t post it in public groups, forums or screenshots. For troubleshooting, the operating system, client, error message and steps you took are usually enough; hide identifying details in screenshots. If you think your link has been exposed, stop sharing it and check the panel for a subscription reset or update option, following the instructions shown. If you can’t find the relevant option, contact support through a ticket. If the link changes, update the configurations on devices still in use. Don’t assume changing your login password will invalidate the old subscription, and don’t overwrite your existing configuration with an unfamiliar subscription from a third party.

Disconnect the client first and check whether your local network can still reach the sites you normally use. If it can’t, troubleshoot the device’s internet connection first. Once the basic connection works, log in to the panel to check your plan and data, update your subscription, then reconnect using a different route. Next, check that the client has actually enabled the system proxy or required network routing mode, and that no other proxy tools are running at the same time. Change one setting at a time and note the results so you can isolate the cause. If the issue persists, submit a ticket with the error message, operating system, client and steps you’ve tried.

If your browser works, that only confirms its current request path is available; it doesn’t mean other apps use the same settings. Some apps don’t use the system proxy, while others connect to additional login, resource or API domains. Check the client’s connection logs to see whether requests from the app are reaching the client and which rule group they match. Then check the client’s instructions to see whether you need to enable a specific network routing mode. You can temporarily switch to global mode for comparison, then restore your original rules. If requests reach the client but still fail, note the app, error page and exit region, then check the routing rules, connection and app-specific regional requirements separately.

For everyday use, start with rule mode. It routes AI tools, streaming services and international sites according to their rules, while local sites can connect directly. The actual route depends on the rules enabled in your client. Global mode is useful as a temporary comparison to see whether a routing rule is causing the issue. It doesn’t replace checking your plan status or resolve account or regional restrictions imposed by a destination service. Note your original mode before switching, then restore it after testing to avoid unnecessary changes to local traffic. If only one domain has a problem, check its rule match first instead of replacing the entire configuration.

First, confirm that the client is compatible with your device’s operating system, then copy the subscription link intended for that client from the panel. A webpage URL, subscription link and local configuration file are different things and aren’t interchangeable. Check that the copied link is complete and doesn’t include extra instructions, line breaks or spaces. Follow the panel’s instructions for importing it into your client. If you already have a configuration, keep its name and a screenshot of the error before reimporting so you can refer back to them. If the format still isn’t supported, don’t submit your subscription to an unknown online conversion site. Contact support through a ticket with the client name and error text to confirm the right import method.

First check whether all network traffic is slow or only traffic using your current route. Pause background downloads, syncing and other tasks that use bandwidth. On the same device and network, compare different routes while accessing the same destination. Try a different exit or route type first, then consider protocol compatibility; avoid changing several variables at once. Changing protocols may not help if your local network is congested. If only one website is slow, the destination’s service status may also be a factor. When submitting a ticket, include when it happened, your network type, the destination app, route used and comparison results. Peak-hour performance depends on routing and congestion, so a route name isn’t a guarantee of fixed speeds or consistent performance.

F4VPN covers 90+ countries / 220+ routes. Check the current panel list for available regions and route types. Direct, relay and IEPL describe different transmission paths; the name alone can’t tell you which route will be faster on your network. First check which exit region the destination service requires, then compare connection quality, ongoing access and how easily the route reconnects after a network change. You can keep alternative routes that suit your needs for everyday use. Rule examples on this page explain routing concepts; they don’t mean every request uses the same exit. Check the actual list for cities, regions and route types rather than inferring them from a name.

Latency mainly reflects the round-trip wait for a request. Download performance also depends on bandwidth, packet loss, congestion and how quickly the destination server responds. So a low latency reading in your client doesn’t guarantee faster large downloads or video loading. To compare routes, keep the device, network and destination the same. Check page load times, sustained transfers and how quickly apps reconnect, and repeat tests during the hours you normally use them. Don’t directly compare results from different tools or destinations, or choose a route for long-term use based on a single test. If pages load quickly but video buffers, check the streaming exit, the platform’s status and your local network—not just latency.

A successful connection only means the connection to the exit has been established. The destination service may also consider your account region, current exit, previous sessions and its own access rules. Confirm that the selected exit matches the service’s regional requirements, then check whether the relevant domains match the expected rule group in your client. After switching exits, close and reopen the app to avoid reusing an old connection. If needed, follow the service’s instructions for clearing or refreshing your session or cache. A successful connection doesn’t guarantee continued access to every platform or content catalog. If the issue persists, include the service name, message, exit region and rule match in a support ticket, and hide sensitive account details.

Monthly plans: ¥9.9/month for 60GB, ¥18/month for 250GB, and ¥28/month for 500GB. Data packs: ¥158 for 300GB, ¥358 for 1000GB, and ¥658 for 3000GB. Monthly plan data resets each month on your activation date, making it suitable for month-to-month use. Data packs last until used and never expire, so you can use them as needed. Decide whether you prefer a monthly reset or keeping unused data, rather than comparing only the payment amounts. Usage frequency, video streaming and sustained transfers all affect consumption, so device count alone isn’t enough to estimate your needs. Check the plans page and current panel details to confirm billing before proceeding.

Alipay / WeChat Pay / USDT are supported. After choosing a plan, follow the instructions on the panel’s order and checkout pages. Before paying, check the plan, amount and order details. If you’ve paid but the panel status hasn’t changed, check the order in your account and make sure you’re logged in to the account that placed it. Save the order details needed for verification. Don’t create and pay for another order for the same purpose just because the page hasn’t updated yet. If you still need help, submit a panel ticket with the order ID, payment method and message shown. Hide unnecessary personal information in payment records. Follow the instructions shown on the payment page; don’t assume a fixed processing time.

F4VPN offers a 60-day money-back guarantee. To request a refund, log in to the panel, open a support ticket, explain your request and provide the relevant order details so the payment can be verified. You can include the order status shown in the panel. If you also want help troubleshooting, add your operating system, client and error message, but make your refund request clear. Read the Terms of Service for refund details; don’t assume F4VPN follows another site’s process. Continue the conversation in the original ticket to keep the information together. Refund processing and payment provider status are confirmed through the ticket and panel; this page doesn’t promise a fixed processing time.

Monthly plan data resets every month on your activation date. If you upgrade mid-cycle, the price difference is prorated for the remaining days. This doesn’t mean every account’s data resets on the same calendar date, so don’t estimate your upgraded status as if a full new cycle had started. Before making changes, check your current plan, data and dates in the panel, then review the order details on the upgrade page. If anything looks different from what you expected, confirm it through a support ticket before proceeding. Data packs last until used and never expire, so the monthly reset rules don’t apply. If your data balance looks wrong, provide your plan type and a panel screenshot, with the full subscription link and sensitive account details hidden.
