VPN beginners often have questions about using multiple devices, data usage, and speed limits. Check your plan, client settings, and network conditions before troubleshooting; this is usually more effective than repeatedly switching servers. Here are answers to 10 common questions, from first-time setup to everyday troubleshooting. Details on VPN37 pricing, refunds, and device limits reflect its published terms.
Can I connect multiple devices at once?
VPN37 has no limit on the number of devices connected at the same time. You can set up computers, tablets, and other mobile devices using the instructions for each platform without choosing a separate plan for every device. But unlimited devices does not mean unlimited data, or a separate full data allowance for each device.
Check usage across devices in your account dashboard; don’t multiply your plan’s allowance by the number of devices. Multiple devices streaming video, downloading files, or syncing cloud storage also share your local network and the bandwidth of the selected route. If one device slows down, pause large transfers on other devices first, then check whether the route is the cause.
Device limits and account-sharing rules are separate matters. “Unlimited devices” does not mean you can publicly distribute your account or subscription link. Check the terms of service for any restrictions on sharing.
How is data usage counted, and why does it run out faster than expected?
Data is the total amount transferred; bandwidth describes how much data can be transferred over time. They are different measures. Video quality, video calls, system updates, and cloud syncing all affect usage. Even a web page can load images, video, and background resources behind the scenes.
Traffic figures from your client, operating system, and the service may differ because they are measured in different places and updated at different times. There’s no verifiable information here about how VPN37 counts uploads and downloads or whether specific routes use a different multiplier, so we won’t speculate. Check the dashboard’s explanation of your allowance or contact support if needed.
To find what’s using your data, pause background downloads, note your remaining balance, and run only the app you want to check. In rule mode, direct connections generally don’t pass through the proxy server, but whether they count toward your service usage depends on the actual routing and billing terms. Don’t assume based on the mode name alone.
How do I choose between a monthly plan and a data package?
If you use the service regularly and your monthly needs are fairly consistent, compare monthly plans. If you use it occasionally or your usage varies, consider a data package. VPN37 data packages remain available until used and never expire. Monthly plan data resets each month on the day you activate the plan, not at the start of the calendar month.
| Type | Price | Data | Billing period |
|---|---|---|---|
| Monthly plan | ¥9.9/month | 60GB | Resets monthly on your activation date |
| Monthly plan | ¥18/month | 250GB | Resets monthly on your activation date |
| Monthly plan | ¥28/month | 500GB | Resets monthly on your activation date |
| Data package | ¥158 | 300GB | Use it whenever you like; it never expires |
| Data package | ¥358 | 1000GB | Use it whenever you like; it never expires |
| Data package | ¥658 | 3000GB | Use it whenever you like; it never expires |
Don’t choose based on data allowance alone. First consider whether you’ll use the service regularly, then compare your budget and remaining data. If you upgrade a monthly plan mid-cycle, the price difference is converted into days remaining. Don’t assume an upgrade starts a new full billing cycle. Check the dashboard for the exact effective terms before proceeding. See the plans and pricing page for details.
Does a slow connection mean I’m being speed-limited?
Not necessarily. Speed depends on your local Wi-Fi, your provider’s routing, route congestion, the destination website, and client settings. Your plan’s data allowance isn’t a speed cap: having data left only means you can still use the service, not that your current route is uncongested.
VPN37’s published information doesn’t specify a universal speed limit, so there’s no basis for promising a particular download speed or attributing a slow connection to an account limit. Troubleshoot in the order below, changing one thing at a time so you can tell what helped.
- Pause background updates and large file transfers. Check whether regular websites load normally on your local network.
- Keep the current route and try another website to see whether the issue affects just one service.
- Keep the same website and try another route in the same region. Compare page loads and sustained transfers.
- Check client error messages, your account balance, and system proxy settings. Then send support the steps needed to reproduce the issue.
Low latency doesn’t always mean faster downloads, and a good short speed test doesn’t guarantee a stable long connection. Judge video by sustained playback, developer tools by session continuity, and file transfers by sustained throughput.
How do I import a subscription link, and what if it fails?
Subscription links are usually used to retrieve a list of servers or configurations; they’re not regular web pages or client installers. Open the download section in your account dashboard, follow the client setup guide to choose an app for your operating system, then import the subscription in the supported format.
Clients differ in the protocols, subscription formats, and configuration syntax they support. An “import subscription” option doesn’t mean every link works with every client. If parsing fails, check the client name and version and the import format offered in your dashboard. A missing character, extra spaces, an incorrect system clock, or an unreachable subscription URL can also cause errors.
If no servers appear after import, check the update result and error message instead of repeatedly adding the same configuration. If the subscription imports successfully but you can’t connect, troubleshoot the connection or routing rather than focusing on the import format.
Subscription links may contain account credentials. Before sharing a screenshot or support ticket, hide the full link, access token, and password. If you need help, provide the client name and a redacted error message.
Do I need to stay connected? How do I choose between rule and global mode?
You don’t need to stay connected just to keep your account active. Whether to leave the connection on depends on the apps you’re using and your network. Meetings, remote sessions, and development tasks may reconnect if the connection drops. When you’re done, disconnect if you like.
Rule mode routes, connects directly, or blocks requests according to your configuration. Global mode generally sends requests handled by the client through the selected proxy. What the client handles matters: enabling the system proxy alone doesn’t guarantee that every app uses it. A virtual network interface mode usually covers more traffic, but routing and exclusions still apply.
For everyday use, start with a well-maintained rule configuration. If an app has issues, check whether the expected rule applies instead of assuming global mode will fix it. If your network behaves oddly after closing the client, check that the system proxy has been restored and that apps aren’t still pointing to a stopped local proxy port.
What’s the difference between dedicated routes, relay routes, and direct connections?
These terms mainly describe the connection path, not the encryption protocol. A direct connection usually means the client connects straight to an overseas entry point. A relay route adds a forwarding node along the way. An IEPL dedicated line uses dedicated Ethernet capacity provided by a carrier. The actual experience still depends on your access network, resource allocation, and onward routing.
A “dedicated line” doesn’t mean every website will be faster, and a “direct connection” doesn’t mean there’s no encryption. Shadowsocks, VMess, Trojan, and VLESS are different proxy protocols or protocol implementations; they aren’t interchangeable with route types. Security also depends on the transport layer and the actual configuration.
When choosing a route, first make sure it meets the destination service’s regional requirements, then compare how stable it is over time. Account region, payment region, and platform rules may all apply; changing your exit location doesn’t guarantee content will be available. See the server locations page for route regions and types. Check platform availability for yourself.
Should I check DNS and privacy after connecting?
Yes. DNS translates domain names into addresses. If DNS requests don’t follow the configured route as expected and instead go to your local network’s resolver, the domains you look up may be exposed. This is separate from whether a website uses HTTPS.
Encrypted DNS in your browser, client DNS settings, the system resolver, and routing rules can interact. Start by checking the client’s recommended configuration, then see whether your browser has its own DNS settings enabled. An unfamiliar resolver alone doesn’t prove a leak, and a changed exit address doesn’t prove that every request is being routed through the client.
Test tools show only some aspects of network behavior at the time of the test. A proxy doesn’t automatically clear website sign-ins, browser identifiers, or account activity. Assess privacy using the service’s published policies, client settings, and your own usage habits; a connection indicator is not a guarantee of anonymity.
Can I use the same client settings on different platforms?
It’s best not to copy settings across platforms without checking. Desktop and mobile operating systems differ in network permissions, background operation, and how proxies handle traffic. Even clients with similar names may offer different features. If a guide doesn’t match what you see, check its platform and version before trying similar-looking settings at random.
On desktop, check for conflicts between the system proxy and virtual network interface. On mobile, look at network permissions, background restrictions, and reconnection when switching between Wi-Fi and mobile data. If something goes wrong after waking the device from sleep, check the connection status before assuming the server is down.
- ✅ Open the client download section in your account dashboard and check the system requirements and instructions.
- ✅ After importing, check the subscription update result and test an actual connection.
- ✅ Keep your current configuration and note your network conditions and error messages before troubleshooting.
- ❌ Don’t run multiple proxy configurations that take over system traffic at the same time; they may conflict on routing and DNS.
What should I know about creating an account, paying, and refunds?
VPN37 doesn’t require an email address to create an account; just choose a username and password. Keep your login details safe, and don’t reuse a password from an important account just because setup is quick. Supported payment methods are Alipay, WeChat Pay, and USDT. Before paying, check the plan type, amount, and activation terms shown in the dashboard.
VPN37 offers a 30-day no-questions-asked refund policy. The exact terms are: you can request a full refund for any reason within 30 days of your first payment. This doesn’t mean each renewal comes with a new refund period. Check the applicable terms or contact support for instructions and processing details.
For help, check the support page or submit an account-related request through the support ticket system. Include your operating system, client, server region, what you were doing, and a redacted error message. This makes it easier to diagnose than simply saying “it doesn’t work.”
