If you're new to VPNs, start by understanding the difference between an account, a subscription link and a client. Your account manages your plan; the subscription link sends route settings to your client; and the client determines which requests use international routes. These 10 answers cover setup, connection, billing and troubleshooting—and explain why a “connected” indicator doesn't mean every app is using the proxy.
Why do I need to configure a client after setting up an account?
Your account is where you manage the service; it doesn't automatically change your device's network route. The client receives your configuration, connects to an exit and applies routing rules. Being able to open the web dashboard doesn't mean other apps on your device are using international routes.
VPNTU accounts can be created with a username and password—no email address required. Sign in to the dashboard to get the client and subscription. For setup steps, see the getting started guide. Avoid downloading apps with the same name from unverified sites, and don't disable all of your device's security checks just to finish setup.
Everyday use of “VPN” and subscription-based proxy services isn't quite the same thing. A system VPN tunnel can carry forwarded traffic, while a proxy client may only handle apps that follow the system proxy settings. To see what is covered, check whether you're using the system proxy, an in-app proxy or a virtual network adapter mode—not just the product name.
How do I import a subscription link, and can I share it for help?
A subscription link usually provides a set of nodes and related settings; it isn't a public webpage address. Some links contain an account access token, which could let anyone who obtains it view route settings or use your account's data. Treat the link like a credential, even if it doesn't include a plain-text password.
- Sign in to the dashboard and choose a client and configuration format for your operating system in the downloads or subscriptions section.
- Copy the relevant subscription link and add it in your client's subscription manager. If you use one-click import from the dashboard, check that it opens the app you intended to use.
- Refresh the subscription, make sure the node list appears, then choose a node and connect.
- Open the site you actually need to use and check the client's connection logs to confirm which rules and exit are being used for its requests.
When asking for help, share the error text, operating system and client version. Hide subscription links, tokens and account details in screenshots. If a link has already been exposed, use the dashboard's available options or contact support to replace the credential.
If importing fails, first check that the full link was copied and that its format is supported. Shadowsocks, VMess, Trojan, VLESS, Hysteria2 and TUIC are different proxy protocols, and client support varies. This list does not claim that VPNTU supports these protocols; use the configuration provided in your dashboard. Renaming a link for one protocol won't make it work as another.
Can I use the service on my computer and other devices at the same time?
VPNTU has no device limit, so you can configure it on multiple devices. That doesn't mean each device gets a separate data allowance or that your home internet has unlimited bandwidth. All devices on the same account share the plan's total data, while your local connection is also shared by downloads, video and sync tasks running at the same time.
Windows and macOS clients may offer system proxy or virtual network adapter modes, depending on the software and permissions. Android and iOS clients typically use the system VPN interface to handle network traffic, but background operation, per-app routing and configuration support vary. On Linux, use a compatible client or core; the steps for other platforms may not apply.
On each device, check that the subscription is up to date and confirm the selected node and routing mode. If a site works on your computer but not another device, compare those settings before assuming the entire route is down. Sharing an account also increases the risk of credential exposure; being allowed to use multiple devices doesn't mean you should share your subscription publicly.
How is data measured, and what's the difference between a monthly plan and a data package?
Data usage is the total amount of data transferred, not how long you're connected. Staying connected uses a different amount from streaming video continuously. Downloads, uploads, cloud sync and background app updates can all use data. Check the dashboard for your measured usage; a downloaded file's size isn't necessarily the same as the amount billed.
| Plan type | Price and data allowance | Allowance period | Best for |
|---|---|---|---|
| Monthly plan | ¥9.9/month · 60GB ¥18/month · 250GB ¥28/month · 500GB |
Data resets monthly on your activation date | Regular use with an estimate of monthly data needs |
| Data package | ¥158 · 300GB ¥358 · 1000GB ¥658 · 3000GB |
Never expires; use it until it's gone | Occasional use, with tasks planned around the remaining allowance |
Data resets on your activation date, not at the start of each calendar month. Don't assume unused data carries over to the next month. If you upgrade mid-cycle, the price difference is prorated for the remaining days. Review the change details shown in the dashboard before proceeding. See the plans page for current options and details.
Does slower performance mean my speed is being throttled?
A slow-loading page alone isn't enough to tell whether your connection is being throttled. Speed depends on your local internet connection, Wi-Fi signal, congestion on international routes, the exit and the destination site's response. Latency measures round-trip delay; throughput measures sustained data transfer. Low latency doesn't guarantee fast large-file downloads.
This page has no evidence of a fixed speed cap for any plan, so we can't promise there is no throttling or blame every speed fluctuation on the service. To troubleshoot, pause data-heavy tasks on other devices, then compare routes on the same network and with the same destination site. Change one thing at a time so the results are useful.
If things lag during the evening peak, check sustained playback or long-lived connections at the time you actually use them—not just a single speed test during the day. If switching routes improves performance to the same destination, the path may be a factor. If local sites are slow too, check your internet connection first.
How do IEPL, relayed and direct routes compare?
A direct route typically connects the client straight to an overseas entry point. A relay route adds an intermediate forwarding hop. IEPL refers to a dedicated transmission path, unlike forwarding over the public internet. These terms describe the route; they don't guarantee a particular speed or eliminate the effects of your local network or destination site.
During evening peak hours, compare how consistently Japan IEPL and Hong Kong IEPL perform over time; for everyday browsing, you can also compare a Singapore relay. If a site requires an exit in a specific region, choose a suitable route such as US IEPL, UK direct or Canada direct. Options depend on what's available in your dashboard, and a route name alone can't guarantee that a site will accept its exit.
VPNTU offers 110+ countries and 180+ routes, giving you options—but not every location will suit every use. For AI tools, check the exit region, account eligibility and platform rules. For streaming, verify the available catalog and playback after connecting. Learn more in our AI Tools guide and Streaming guide.
What's the difference between rule-based and global mode?
Rule-based mode uses conditions such as domains, addresses or apps to decide whether traffic connects directly, uses a proxy or gets blocked. It's useful for handling local services and international sites separately. Global mode usually sends requests handled by the client through the selected proxy, but it doesn't necessarily cover all system traffic: apps that ignore the system proxy may still use another route.
Virtual network adapter mode can cover more traffic, but its behavior still depends on routing, DNS settings and the software implementation. If you're new to this, start with a suitable default configuration. If a specific site has problems, check which rule applies. Changing rules, DNS and nodes all at once makes it difficult to find the cause.
- ✅ If a local service stops working, check whether its traffic was mistakenly routed internationally.
- ✅ If an international site won't open, check whether its domain was inadvertently matched by a direct-connection rule.
- ✅ If an app ignores the system proxy, check whether the client offers a compatible way to handle its traffic.
- ❌ Don't assume “global” mode automatically protects every app and every DNS request.
Do I need to keep it on all the time? What happens when I disconnect?
You don't need to stay connected just to keep your account active. Connect when accessing international sites, using relevant apps or protecting traffic on public networks. If you're only using local services, decide whether to stay connected based on your routing settings and experience.
After disconnecting, traffic that used the proxy may go direct again, or you may lose internet access if proxy settings remain in place. The result depends on how you exit the client. Disconnect in the app before quitting; if the network stops working afterward, check whether the system proxy still points to a local service that has stopped.
Downloads, meetings and AI chats in progress may be interrupted when your exit changes. Switch nodes or close the client between tasks when possible. After changing networks or waking a device from sleep, check the connection status again instead of relying on an icon you saw earlier.
What are the limits of privacy protection when connected?
An encrypted connection mainly protects data in transit along the routes it covers. It can't replace a website's own authentication or stop you from voluntarily submitting information. VPNTU's primary trust message is quantum encryption, but that label doesn't mean every app is covered or replace checks of client settings, HTTPS and credential security.
A DNS leak occurs when domain lookup requests don't follow the expected route—for example, when a page loads through a proxy but its DNS queries go to your local network's DNS service. To assess whether a leak is happening, check the client's DNS policy, system settings and your browser's encrypted DNS configuration. The exit address shown by a website isn't enough on its own.
On public Wi-Fi, verify that you're on the right network, watch for certificate warnings and avoid entering account credentials on unfamiliar sign-in pages. Claims about no logs or not recording browsing activity describe a service's privacy policy; read the policy itself. They don't mean websites, browsers or your device keep no records.
If you see a certificate error, don't disable certificate checks as a routine fix. Check your device's clock, the destination address and the network first, then contact support for help.
Connected but can't open a site? Here's how to troubleshoot
“Connected” may only mean that the local proxy has started or that part of the connection process has completed. It doesn't guarantee that the destination site is reachable. Follow these checks in order to avoid configuration problems caused by repeatedly reinstalling the app.
- Check your account. Review your plan status, remaining data and dashboard notices, and confirm that the subscription updated successfully.
- Check traffic handling. Confirm that the system proxy or virtual network adapter is active, and close other proxy apps that might conflict.
- Check the destination. Try other sites. If only one site fails, check its regional requirements, account eligibility and service status.
- Check the route. Try another route in the same region, then compare other regions for your use case. Avoid switching locations repeatedly, as this can trigger extra account verification.
- Check DNS and rules. Look for DNS or rule errors in the connection logs. Keep a copy of the original configuration before making changes based on the guide.
- Get help. Look for relevant instructions in the Help Center. If the issue persists, send customer support error details with sensitive information removed.
If the client connects but a site explicitly says your region isn't supported, reinstalling the client is unlikely to help. Check the platform's supported regions and account requirements. VPNTU offers a 60-day money-back guarantee; still, make sure the service fits your needs before choosing a plan.
