VPNBasicsFAQ: 10 Common Questions Answered
Can you use one VPN on multiple devices? How is data counted? Could speeds be limited? Should it stay on? Get answers to 10 common beginner questions.
VPN beginners often have questions beyond “Where’s the button?” After connecting, which apps use the VPN, how does data usage change, and what should you check if things slow down? Understand the difference between a subscription, a client, and your network path, then troubleshoot based on what you observe instead of reinstalling software at the first sign of trouble. Here’s a practical, step-by-step guide.
1. Can I use the same subscription on multiple devices at once?
VPNOU has no limit on the number of devices connected at once. Install a compatible client on each computer, tablet, or other device, then import the subscription provided for your account. Keep in mind that unlimited devices doesn’t mean each device gets its own data allowance: all usage on the account draws from the same plan, and each device is also affected by its local network.
Before adding a device, check that its client supports the protocols and configuration formats in your subscription. A subscription link is a credential for retrieving connection settings, not a regular software download link. Don’t post it in public chats or submit it to an unfamiliar conversion site. If it’s exposed, reset the link if your account panel allows it, then update your devices.
If you use several devices, give each configuration a clear local name in the client. To investigate unexpected data usage, pause connections one device at a time and check how the account usage changes. That’s more useful than assuming the number of devices caused a speed limit.
2. How is data usage calculated, and should I choose a monthly plan or a data package?
Browsing, video streaming, downloads, cloud sync, and background app requests can all use data if they pass through the subscription route. The client’s usage display may show only the current session or traffic on that device, so it may not match the service’s billing records. Check the account panel to see whether uploads are included and whether any routes have a usage multiplier. Don’t infer billing from a generic client’s counter.
| Billing option | Available allowances and prices | How the allowance works |
|---|---|---|
| Monthly subscription | ¥9.9 / 60GB;¥18 / 250GB;¥28 / 500GB | Data resets monthly on the activation date |
| Data package | ¥158 / 300GB;¥358 / 1000GB;¥658 / 3000GB | Never expires; use it until it runs out |
If you use the service regularly and your monthly needs are fairly consistent, compare monthly subscriptions. If you use it less often and want an allowance based on actual consumption, consider a data package. Don’t estimate usage based only on the number of devices: high-resolution video, automatic backups, and large file syncs can use far more data than ordinary browsing. See the plan details for the full terms.
3. Does a slow connection mean my speed is being limited?
A single slow download isn’t enough to draw that conclusion. Weak Wi-Fi, broadband congestion, background uploads, route load, or limits imposed by the destination site can all be bottlenecks. Latency measures how long a request takes round trip; download speed reflects transfer capacity; jitter and packet loss affect real-time interactions. These metrics measure different things.
For a fair comparison, keep the device, network, destination, and client mode the same. Pause background downloads, make sure your regular connection is working, then try another route. A speed test shows performance to that test server—not the speed of every website—and it can’t by itself prove that the service is limiting speeds.
4. Do I need to keep the VPN on? What happens if I quit the client?
Whether to leave it on depends on what you’re doing and how the client is configured. If you regularly visit sites that use the VPN route, keeping the client running with suitable split-tunneling rules can save effort. Disconnect it when you don’t need it. An active connection doesn’t necessarily use a lot of data, although background apps may still send requests.
Know the difference between closing a window, quitting the app, and stopping the proxy. Some desktop clients keep running in the background after you close the window. If the app quits while your system proxy still points to a local listening address, your browser may be unable to load pages. Reopen the client to reconnect, or use its controls to turn off the system proxy properly rather than changing system network settings at random.
Tunnel mode may cover more apps, but its actual reach depends on platform permissions and routing settings. If the client offers a kill switch, understand what it does and test it first: it may block internet access when the connection drops, but that doesn’t mean your network itself is faulty.
5. How should I choose a route? Should I always pick the lowest latency?
Choose a region based on what you need first, then compare real-world performance. Web browsing and interactive tasks may benefit from quick response times; video and downloads depend more on sustained throughput. If an account expects you to connect from a particular region, check whether the exit region changes. Frequent changes of country or region may trigger account security checks on the destination site.
A latency test in the client may check only whether a node is reachable or measure performance to a probe address. A low reading doesn’t guarantee smooth video playback. After switching routes, reload the site and, if needed, close existing connections—already established connections may not immediately use the new route.
IEPL dedicated lines, relays, and direct connections describe different ways of routing traffic. A dedicated line may be used for some of the provider’s cross-region traffic; a relay forwards traffic through an additional entry point; direct connection usually means the client connects straight to the destination node. These labels don’t prove that the entire route is exclusively yours, and they don’t replace testing your current network and destination. See the route list and your client for available options.
6. Subscription import failed. What should I check first?
First identify whether the failure occurs while downloading the subscription, parsing its configuration, or connecting to a node. A download failure may be caused by an expired link, an incomplete copy, or network access. A parsing error is more likely to involve the format or client compatibility. If nodes appear but won’t connect, check the subscription status, selected node, and connection logs.
- Sign in to the account panel, check that the subscription is active, and copy the full link again. Make sure it doesn’t include extra spaces or line breaks.
- Add the link through the client’s subscription or configuration manager. Don’t paste it into the browser’s proxy server address field.
- Check the import format. Not every client supports automatic detection. If you see a compatibility warning, return to the account panel and choose a suitable configuration.
- After updating the subscription, make sure the node list appears, then select a route and enable the proxy mode you need.
- If the problem persists, keep the error message. Before submitting a support ticket, redact the subscription URL, account credentials, and any authentication details in the configuration.
Don’t submit your subscription URL to an unfamiliar online conversion tool. If your client needs a specific format, use the format provided in the account panel and follow the setup guides. Don’t publish your full configuration just to troubleshoot an import issue.
7. Are the setup steps the same on Windows, macOS, Android, and iOS?
The basic steps are similar: get the configuration, import it, choose a route, connect, and test the app you want to use. The differences are mainly in client features, system proxy support, and tunnel permissions. On Windows and macOS, not every app follows the system proxy. Android and iOS often use the system’s VPN interface to create a local tunnel, but per-app exclusions and other routing differences may still apply.
Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different protocols or protocol families. Not every client supports them all, and support for a protocol with the same name doesn’t guarantee every setting is compatible. They aren’t speed modes that you need to try one by one, and their names don’t mean VPNOU offers every protocol.
Choose a client based on the compatibility guidance in the account panel. VPNOU installers are available only to users with an active subscription through the account panel. Sign in there to get your subscription and client. Don’t assume an app is the right one just because its name looks similar to the recommended software.
8. What’s the difference between split tunneling and global mode? Why don’t some apps change?
Rule-based routing uses domains, addresses, apps, or other matching criteria to decide whether requests connect directly, go through a proxy, or get blocked. Global mode usually sends traffic already handled by the client through the selected proxy, but it doesn’t mean every app on the device is covered. System proxies, tunnel modes, and browser extensions have different scopes.
If your browser works but another app behaves the same, check whether that app follows the system proxy and whether a direct-connection rule applies. You can temporarily switch to global mode for comparison. If nothing changes, check whether the app’s traffic is reaching the client rather than repeatedly updating the subscription. Once you find the cause, restore rules that suit your regular use so large downloads that could connect directly don’t consume subscription data unnecessarily.
Some rules rely on domain lookup results. DNS settings that don’t match the rules may cause them to fail or send traffic along the wrong route. Don’t combine rule sets, DNS settings, and existing configurations you found online without checking compatibility.
9. Does connecting mean I’m protected from DNS leaks?
Not necessarily. DNS translates domain names into network addresses. Even when web traffic goes through a proxy, DNS requests may still be handled by your local network’s resolver. Whether that counts as a leak depends on your expected route, the client’s DNS policy, and where the requests actually go—not just whether the status bar says you’re connected.
Encrypted DNS in your browser, the system resolver, the client’s built-in resolver, and IPv6 routing can all affect the results. A detection page showing an unfamiliar resolver doesn’t prove there’s a problem. Likewise, a changed exit address doesn’t prove that every DNS request went through the tunnel. Check the client logs and supported configuration together.
Connecting through a service won’t remove identifying information from website accounts, cookies, or your browser. For privacy, also pay attention to signed-in accounts, site permissions, and device security updates. An encrypted connection doesn’t replace these everyday precautions.
10. First time using a VPN? How can I check that it’s set up correctly?
Don’t rely on the connection button changing color. Confirm the configuration imported successfully, then check your exit address, access to the destination, and the app you’re actually using. Finally, see what happens after reconnecting. Use this checklist as a starting point for future troubleshooting.
- ✅ The subscription is active in the account panel, the client has loaded the nodes, and the selected route is clearly identified.
- ✅ Check your current browser exit address with My IP. Keep in mind that it only reflects the route used for this web request.
- ✅ Open the websites and apps you actually plan to use and check that routing works as expected—not just that a speed test runs.
- ✅ After switching networks or reconnecting, check that the system proxy, tunnel permissions, and node status are back to normal.
- ✅ Close background tasks that use a lot of data if you don’t need them, then check usage in the account panel to understand your typical pattern.
- ❌ Don’t assume a successful connection covers every app, and never send your full subscription link to someone else.
If you need help, include your device’s operating system, client name, selected route, affected app, and any error message. Describe what happened first, then list the checks you’ve already tried; that’s usually more helpful than simply saying “it doesn’t work.” No email address is required to open an account. For help while using the service, submit a support ticket through the account panel, or see the FAQs for general guidance.
