VPN beginners often have questions about accounts, data and connection settings. The short answer: VPNXB has no device limit; monthly plan data resets on the activation date, while data packs never expire. A smooth connection also depends on your local network, client rules and the destination site's regional requirements—not just whether the connection indicator is on.
1. Can you use a VPN on multiple devices at once?
Yes. VPNXB has no device limit. It supports Windows, macOS, iOS, Android and Linux. The number of devices and the plan's data allowance are separate considerations: when several devices share one account, budget for their combined usage rather than treating each device as having its own allowance.
When one device downloads files, video streaming on other devices may use data at the same time. No device limit does not mean every device gets a fixed speed; the shared local network, Wi-Fi signal and outbound route all affect performance. If your home network is congested, pause large downloads first and see if that helps.
Connection permissions and background behavior vary by operating system. Desktop clients may require system proxy or virtual network adapter mode; mobile devices usually ask for permission to add a VPN configuration. Grant only the permissions the client requires, and don't change system settings you don't understand just to make the status show as connected.
2. How is data counted, and when does it reset?
Monthly plan data resets each month on the activation date, not at the start of the calendar month. Video, downloads, app updates and background sync can all use data, depending on whether those connections go through the service's routes. A connection being on without active data transfer does not mean it is constantly using a large amount of data.
Usage shown in the client and account dashboard may differ because they refresh at different times or track different traffic. Don't use your operating system's total network usage alone to estimate plan usage, as it may include direct connections. Check the account dashboard and plan details for billing scope and remaining data; this article does not assume separate upload or download billing rules.
| Billing option | Price and data | Data validity | How to choose |
|---|---|---|---|
| Monthly plan | ¥9.9/month, 60GB ¥18/month, 250GB ¥28/month, 500GB |
Resets monthly on the activation date | For regular use; choose a tier based on your actual usage |
| Data pack | ¥158/300GB ¥358/1000GB ¥658/3000GB |
Use it at your own pace; it never expires | For infrequent use when you don't want a monthly reset |
If you upgrade a monthly plan mid-cycle, the price difference is converted into the remaining days. Check the amount shown in the dashboard before upgrading; don't assume the full monthly prices of the two tiers are simply subtracted to calculate what you owe. A reset does not mean unused data necessarily carries over, so don't assume rules that haven't been published.
3. Does slow performance mean you're being throttled?
Not necessarily. Route distance, congestion at the exit, Wi-Fi interference, the destination site's load and your local ISP's routing can all affect speed. Latency measures how long a request takes to make a round trip; throughput measures sustained transfer capacity. A responsive webpage doesn't guarantee fast large-file downloads, and vice versa.
VPNXB has not published a fixed bandwidth or throttling threshold. We can't promise a fixed speed or claim that every slowdown is caused by plan limits. To troubleshoot, first check whether ordinary websites are also slow without the proxy. Then compare routes using the same destination and local network, so you don't mistake a website-side issue for a service issue.
IEPL generally refers to an international Ethernet private line and describes the transport path. A relay forwards traffic through an entry point, while a direct route avoids an additional relay entry point. These labels alone don't prove end-to-end quality; the destination site and your local connection can still be bottlenecks. Check the client and node details for the specific route type VPNXB provides, and don't treat geographic coverage as proof of a private line.
4. Do you need to keep your VPN connected?
Keeping it connected all the time isn't the only right way to use a VPN. If you only need a route for international websites, connect when needed. For apps to choose routes automatically, use a rules mode supported by your client. Note that global proxy mode usually means only traffic handled by the client goes through the proxy; it doesn't necessarily cover every program on your device.
System proxy settings mainly affect apps that follow them; some programs may ignore them. Virtual network adapter or TUN mode can capture more traffic at the network layer, but routing, exclusions and DNS settings still matter. Check the client documentation and test with the apps you use instead of judging coverage by the mode's name alone.
A VPN connection can affect local network printers, corporate intranets or local services. If that happens, check your direct-connection rules first rather than repeatedly changing every setting. If you want network access to stop when the connection drops unexpectedly, confirm that your client offers and has enabled the relevant protection; don't assume every client does this by default.
5. How do you import a subscription link into a client?
A subscription link is for importing configuration, not downloading a client. It may contain credentials used to retrieve node configurations, so protect it like an account password. Get the client and subscription from your VPNXB user dashboard, then follow the import method available in your client. Never post the link on a public forum or paste it into an unfamiliar online converter.
- Go to the client download section in the user dashboard, choose a client for your device's operating system, and read its setup instructions.
- Copy the subscription link from your account, open the subscription or configuration management page in the client, and choose the option to import from a link. Menu names vary by version.
- Refresh the configuration and check that it appears in the list, then select a route. If the refresh fails, check that the link is complete, your account is in good standing and your local network can retrieve the configuration.
- Grant the connection permissions required by your system, enable proxy or virtual network adapter mode as instructed, then test by visiting a website that needs the route.
When asking for help, hide your subscription link, password and any authentication details in the configuration. A screenshot only needs to show the error message and client name. If your credentials have been exposed, change them through the dashboard if that option is available, then update your configuration.
6. There are many protocol names. Do you need to choose one?
Beginners should start with the configuration provided for their service. Shadowsocks, VMess, Trojan, VLESS, Hysteria2 and TUIC are different proxy protocols, not a universal speed ranking. The protocol, configuration format and transport settings must be supported by your client and match. Being able to paste a link doesn't guarantee it will work correctly.
Trojan uses TLS to establish a protected transport; VLESS does not provide encryption on its own and needs an appropriate secure transport configuration. Hysteria2 and TUIC use QUIC, so network restrictions on UDP may affect the connection. A protocol name is not a complete configuration, and it shouldn't be taken to mean VPNXB supports every protocol listed.
Protocols, transport layers and route paths are different layers of configuration. Changing protocols may not fix congestion at the exit, and changing regions may not correct invalid authentication settings. If an import fails, first check client support and subscription format. For an overview of how protocol names relate to configuration, see the protocol reference; don't change parameters provided by the service at random.
7. Why won't a website open even though the client says connected?
Connected usually means the client established a connection, not that the destination website is reachable. The app may not be using the proxy, a split-tunneling rule may have sent traffic direct, DNS resolution may have failed, or the website may be down for maintenance. First work out whether all destinations fail or just one, then decide whether to check the client or the website.
- ✅ Check the client's current mode and matching rules. Make sure the destination domain hasn't been incorrectly assigned to a direct or blocked rule.
- ✅ Check the system clock, configuration status and remaining account data. Keep the exact error message instead of just noting that it doesn't work.
- ✅ Keep the destination website the same and try another route offered by the client to see whether the problem changes with the route.
- ✅ Check your browser cache, extensions and secure DNS settings; the browser's built-in DNS resolver may behave differently from the client's settings.
- ❌ Don't run multiple tools that change system proxy or routing settings at the same time and mistake a conflict for a failed route.
Streaming services may also check account region, payment region, content licensing and characteristics of your exit IP address. Connecting through a route in a particular country doesn't guarantee access to all region-specific content. Review the platform's rules first. For route selection, see the streaming access guide; occasional playback shouldn't be treated as a lasting guarantee.
8. What do DNS leaks and encryption each protect against?
Encryption protects data in transit, while DNS settings determine how domain lookups are sent; they are not substitutes for each other. VPNXB describes its security as bank-grade encryption, but that doesn't eliminate risks from website logins, malicious attachments or malware on your device. Always check the domain name and HTTPS status when visiting a website.
A DNS leak generally means domain lookups that were expected to use a protected route were instead sent to a resolver outside that route. Client configuration, the operating system's DNS behavior and browser secure DNS settings can all affect where lookups go. In rules mode, a domain intentionally routed directly may use local DNS; that isn't necessarily a configuration error. Check whether the behavior matches your intended routing.
To check, start with the client's DNS and routing documentation, then use a trusted test page to see whether the exit and resolver match your expectations. Test results only reflect that browser and connection at that moment; they can't prove that every app on your device is covered. A proxy service doesn't make you anonymous: websites may still identify you through your account, cookies or browser fingerprint.
9. Do you need an email address to create an account, and how do you choose a plan?
VPNXB doesn't require an email address; create an account with a username and password. Save your username and use a unique password that you don't reuse on other sites. Alipay, WeChat Pay and USDT are supported; available options and the payment process are shown in the dashboard. For payment or account issues, contact support through the account portal.
If you use the service regularly and your usage is fairly consistent, compare the monthly plan tiers. If you use it infrequently, consider a data pack that never expires. It's more sensible to check your actual usage before changing plans than to pick a larger plan based on the number of devices. VPNXB covers 100+ countries and 180+ routes; choose based on your destination and use case, not just the total number of routes.
If you're considering both a monthly plan and a data pack, check the dashboard for how charges are applied and how each option works. The published details don't specify which takes priority when both are used, so don't assume data will automatically be deducted in the most favorable order. Check the plans page for prices and applicable terms.
10. Can you get a refund if the service isn't right for you?
VPNXB offers a 60-day, no-questions-asked refund. You can request a full refund within 60 days of your first payment. The period starts with the first payment; a later upgrade doesn't restart the refund window. No processing time or additional conditions have been published, so don't assume any.
If you have connection issues, note your device's operating system, client name, selected region and error message, then contact support through the support section in the user dashboard. If you want a refund, make an explicit refund request; submitting a technical support ticket doesn't count as completing one. Share account information only through the appropriate support channel.
