Frequently Asked Questions

No email address is required. Create an account with a username and password. After opening the user dashboard, follow the on-screen instructions to set your login details and store them in a trusted password manager. Dashboard login details and subscription configurations in a client serve different purposes: connecting to a route does not mean your account password has been saved. You’ll need the original account to check plans, retrieve your subscription or submit a support ticket. If you can’t log in, check capitalization, your input method and any extra spaces copied with your details. Make sure you’re on the user dashboard, not using a subscription link as a login page. Never post your password or full subscription link in a public forum.

Sign in to the user dashboard and retrieve your current subscription details from the subscription section. Then return to the subscription or configuration page in your client, select the relevant configuration and update it. Once the update is complete, check that the route list has loaded before connecting. You usually don’t need to import the subscription again just to switch routes. If the client says the address is invalid, your subscription details have changed, or the existing configuration keeps failing to update, retrieve the latest details from the dashboard. Before making changes, confirm that you’ve selected this service’s configuration so you don’t overwrite another one. Subscription links contain access credentials, so don’t include the full address in screenshots. If you describe an issue, hide the credentials in the link.

There’s no limit on the number of devices connected at the same time. Supported platforms include Windows / macOS / iOS / Android / Linux. To set up a new device, sign in to the user dashboard with your existing account, follow the instructions for that platform to get the client and subscription details, then import the configuration and verify the connection. You don’t need a new plan just because you changed devices. Menu names vary between clients, and local rules on an old device may not transfer automatically with the subscription, so check routing mode and app settings on each device. Unlimited simultaneous connections don’t mean each device has a separate data allowance. Check your plan details in the account, and keep subscription configurations secure on every device.

4BVPN’s privacy policy is not to keep logs. Refer to the Privacy Policy for details about data handling. This policy doesn’t mean that the websites you visit won’t record sign-in activity or that your device’s browsing history is automatically cleared. The services you visit, your browser and this service are separate, and each has its own privacy settings. When submitting a support ticket, you can share your device platform, the client’s error message, what you were doing and the steps you’ve already tried to help identify the issue. There’s no need to include your password, full subscription link or unrelated browsing details. Before sharing a screenshot, check for account identifiers and credentials; keep only the error text needed to investigate. The privacy policy and the troubleshooting information you choose to provide are separate matters.

First, check that your device can access the user dashboard. Make sure you copied the subscription details provided there, not a marketing page or sign-in page address. Extra spaces, an incomplete copy or an import method the client doesn’t support can all cause errors. Go to the client setup section in the dashboard and follow the instructions for your platform instead of guessing the link format. If the configuration appears in the client but the route list is empty, update the configuration and check the exact error message, then confirm your plan status in the account. If the problem persists, include the error message, device platform and whether the failure occurred during import or update in a support ticket. Avoid repeatedly deleting the configuration, which can remove useful troubleshooting clues.

A connected status usually means the client has established a connection; it doesn’t guarantee that requests from your target app are going through the selected route. First check that the system proxy or relevant traffic-routing feature is enabled. Then check whether the client is using rule mode or another mode, and make sure the target domain isn’t set to connect directly. Use a network check page to view your browser’s current exit information, then test both a regular website and the service you’re trying to access. If only the target service fails, check its supported regions, your account status or the error shown in the app. If regular websites also fail, try another route and check your local network. A network check only reflects the path taken by that request; it doesn’t show that every app on your device uses the same exit.

A browser and a standalone app may use different network paths. Some apps ignore the system proxy, and the client may exclude specific apps or route certain domains directly. That’s why a working browser doesn’t confirm that the app is routed correctly. Check whether the client excludes the app, then review the rules to see if its domains are set to connect directly. The app may also keep an old connection or use its own DNS cache. After changing settings, fully close and reopen it. If the issue continues, follow the client’s official instructions for its traffic-routing mode. Don’t run multiple tools that take over network traffic at the same time. When contacting support, include the app name, platform and error message rather than simply saying the connection doesn’t work.

First, determine whether all network access is dropping or just the client connection. Check whether your device switched local networks, entered battery-saving mode or is running another traffic-routing tool at the same time, then test again on the same route. If the connection works on another local network, focus on the original network environment. If only one route has problems, try another and see whether the issue persists. In your support ticket, include your device platform, the route name shown in the client, what you were doing when the drop occurred, the full error message and the steps you’ve already tried. Hide passwords and subscription credentials in screenshots. A clear sequence of steps that reproduces the issue is more useful than repeatedly reconnecting.

Check the route and your local network first; don’t assume buffering is caused by your plan’s data allowance. Keep the same video and service, pause large downloads on your device, then try another route suited to the service’s region. You can also switch to another local network to see whether the problem follows the network. Video quality settings, the platform’s service status and your device’s ability to decode video can all affect playback. A plan’s data allowance determines how much data you can use; it isn’t a speed guarantee. If buffering continues under the same conditions, tell support the platform, route name and what happens: whether playback is slow to start, buffers frequently or stops during playback.

These terms describe different network paths, not a speed ranking that applies in every situation. IEPL refers to a dedicated-line connection; a relay uses an intermediate connection point, while a direct route connects to the destination route directly. Actual performance still depends on your local network, exit region and target service. Start by identifying the service and region you need, then compare routes under the same conditions rather than judging by the route name alone. If the service requires a particular region, matching the exit region matters more than the route type. When you’re in the middle of a session, avoid switching exits repeatedly. If an issue occurs, compare routes under consistent conditions so you can keep useful troubleshooting details.

4BVPN offers 100+ countries / 210+ routes. Check the user dashboard and the latest client route list for currently available options. Coverage describes the range of routes you can choose from; it doesn’t mean every website is available through every exit or that every route suits every use case. Before connecting, check which regions the target service supports, then see whether a matching route is included in your current subscription. If the dashboard and client show different lists, update the subscription configuration before relying on an older local list. The routes page can help you compare regions and types, but actual access also depends on your account region and the target platform’s rules. The number of countries covered isn’t a guarantee that every third-party service will work.

Not always. A platform may consider your exit region, account region, payment region, sign-in history and app cache. Switching routes alone may not change the outcome. First, check which regions the platform officially supports, then make sure the client routes the app through an appropriate exit. Fully close and reopen the app and see whether the error changes. Avoid switching between multiple regions repeatedly in a short period. If the page loads but account features are restricted, check the platform’s account guidance rather than treating every restriction as a connection problem. This service provides international routes; the platform itself decides content licensing, eligibility checks and account actions. Follow the target service’s terms when troubleshooting.

Monthly plans are ¥9.9/month for 60GB, ¥18/month for 250GB and ¥28/month for 500GB. Data resets monthly on the day your plan starts. If you upgrade mid-cycle, the price difference is prorated for the remaining days. Compare plans based on your actual usage and whether you expect to use the service regularly; the route name alone won’t tell you which data allowance you need. Resets follow your plan’s start date, not the calendar month, so check the start date and details shown in your dashboard. Before upgrading, review your current plan and the order terms in the user dashboard. Don’t assume the price difference will simply be converted into an equivalent amount of data. Confirm order status and account changes in the dashboard; the public plans page explains prices and terms.

Data packages cost ¥158/300GB, ¥358/1000GB and ¥658/3000GB. They last until used and never expire. Their terms differ from monthly plans, which reset data each month based on the plan start date. When comparing them, consider whether you’ll use the service regularly or at irregular intervals. Never expiring describes the package validity period; it doesn’t mean data is automatically replenished when used up or renewed each month. To check your remaining data, sign in to the user dashboard and review your plan and usage details. The client’s local usage counter can help with troubleshooting, but it shouldn’t replace the account record. If you plan to switch plan types, check the order terms in the dashboard rather than assuming balances will be combined or credited.

We support Alipay / WeChat Pay / USDT. Select a plan in the user dashboard and follow the checkout instructions. After paying, return to the order page to check its status, then review your plan details in the account. If your payment method shows that you’ve been charged but the dashboard hasn’t updated, make sure you’re signed in to the account used to place the order and confirm that the order matches your payment. Don’t place the same order again just because the client hasn’t updated, and don’t send money to unknown payment details outside the site. If you need help, submit a support ticket through the user dashboard with the order reference, payment method and current status. Include proof of payment with sensitive details hidden; never send your payment or account password.

4BVPN offers a 7-day, no-questions-asked refund policy. To request a refund, sign in to the user dashboard for the account that placed the order, submit a support ticket explaining your request and include the relevant order reference. Read the full refund terms in the Terms of Service before submitting. If the page status doesn’t match the payment, you can include the payment method and proof with sensitive details hidden to help verify the transaction. Don’t send your payment password or full subscription link. Requesting a refund is different from simply stopping your connection; deleting the client doesn’t submit a request. Follow the request and its status in your support ticket. This page doesn’t promise a processing time; check the dashboard for updates rather than relying on your device’s connection status.
