Here’s the short answer to these VPN FAQs for beginners: VPNVZ has no device limit, but all devices share the plan’s data allowance. Monthly plans reset each month on the activation date, while data add-ons never expire. As for speed limits, device count, data allowance, and actual connection speed are separate things. We’ll cover each one below.
In this guide, “client” means the software on your device that connects to the service. A “subscription” is how server configurations are delivered to the client. Your plan determines the features available, while the client determines how those configurations work. Knowing the difference can save you from switching plans or reinstalling software when something goes wrong.
Can I use a VPN on multiple devices at once, and how is data counted?
VPNVZ has no device limit. You can configure it on Windows, macOS, iOS, Android, and Linux. Clients and supported configuration formats can vary by platform, so follow the setup guide for your device.
No device limit doesn’t mean each device gets its own data allowance. All devices on the same plan share the same data. Watching a video on your computer while another device syncs files can use data at the same time. Check activity across your devices, not just the one you’re currently using to browse.
The number of devices isn’t a speed guarantee, either. Multiple devices transferring large files at once can compete for bandwidth on your local network. If your connection slows down, pause downloads or cloud backups on other devices before deciding there’s a route issue. Keep subscription links only on trusted devices, and never share the full link to get help troubleshooting.
How is VPN data counted? Does it get used while connected but idle?
Data usage measures how much information is transferred, not how long you’re online. Browsing, streaming video, uploading attachments, and downloading files can all use data. Background activity—such as autoplay, app updates, and cloud sync—can keep transferring data even when you aren’t actively using your device.
The cumulative data shown in your client may not match the amount deducted from your plan. The client’s figure may include direct traffic, data from a different reporting period, or connection overhead. The service may also use its own billing method. Check the dashboard and plan details to see how uploads and downloads are counted and whether any specific multiplier applies. Don’t infer this from the client’s display alone.
Even with a connection established and no active traffic, small amounts of data may be used for connection maintenance. So “I haven’t opened a webpage” doesn’t necessarily mean your data usage stays the same. If usage seems unusually high, check background activity and split-tunneling logs first. Avoid relying on unverified estimates like how much data a movie uses.
When does a monthly plan reset? Do data add-ons expire?
VPNVZ monthly plan data resets each month on the activation date, not at the start of the calendar month. Check your dashboard for the end date of the current cycle. Don’t use the calendar month to guess when your data will reset, and remember that a data reset doesn’t mean you need to reconfigure every device.
| Type | Price and data | Data terms |
|---|---|---|
| Monthly plan | ¥9.9/month includes 60GB; ¥18/month includes 250GB; ¥28/month includes 500GB | Resets monthly on the activation date |
| Data add-on | ¥158/300GB；¥358/1000GB；¥658/3000GB | Use it until it’s gone; it never expires |
If you upgrade a monthly plan mid-cycle, the price difference is prorated based on the remaining days. Check the dashboard for the exact result; don’t assume the upgrade starts a new full cycle. Check the dashboard details to confirm whether unused monthly data carries over, whether products can be combined, and which balance is used first. The “never expires” rule applies to data add-ons.
Are there speed limits? Why does the same route sometimes feel faster or slower?
The available plan details don’t specify a speed cap or guaranteed bandwidth. So we can’t promise there are no speed limits, or assume a fixed limit applies. A data allowance determines how much you can transfer; bandwidth affects how fast you can transfer it. They aren’t interchangeable.
Your experience depends on factors such as local Wi-Fi, your broadband connection, route congestion, network paths, and the destination website. Lower latency often helps with responsiveness, but doesn’t guarantee faster downloads over time. Video buffering may also be caused by the streaming platform or your local network, rather than an intentional restriction by the service.
To compare routes, keep your device, network, and destination website the same and switch only the route. Pause background downloads, then check whether the same content loads better. A single speed test reflects conditions at that moment. If several routes have trouble reaching the same site, test another site too so you don’t mistake a website issue for a route problem.
Do I need to stay connected? How do rule-based and global modes differ?
You don’t need to stay connected just to keep the service “active.” Connect only when you need it to reduce unnecessary background data use. If your daily work relies on international websites, you can leave the client running, but check your split-tunneling rules and connection status after your device wakes from sleep.
Rule-based mode uses criteria such as domains and addresses to decide whether traffic goes through the proxy or connects directly. It works well when you use both local and international services. Global mode usually sends traffic the client can handle through the selected proxy, but it doesn’t necessarily cover every program on your device. System proxy and virtual network interface modes cover traffic differently, and client permissions can also affect what gets routed.
A client showing “Global” doesn’t mean it has taken over traffic from every app. To check how a specific app is routed, review its connection logs and matching rules instead of relying on the mode name.
If you’re new to the service, start with the rule configuration in the guide. If an app can’t connect, check whether it matched a direct or proxy rule before changing anything. Avoid routing all traffic the same way long-term just to fix access to one website.
How do I import a subscription link, and why won’t some clients recognize it?
A subscription link retrieves route configurations; it isn’t an installer. VPNVZ doesn’t require an email address. Open your dashboard, then use the client page and setup guide to find a compatible configuration. You need to log in to access your subscription; check your dashboard to see which clients are supported.
- Check your operating system and client name, then follow the matching guide. Don’t use import instructions for a different app.
- Copy the correct subscription link from your dashboard. Keep the full link intact; don’t remove or edit any parameters.
- In your client, choose the option to import a subscription or configuration. Once it’s imported, update the configuration and check that the routes appear.
- Choose a route and connect, then test it with a website you need to access.
Shadowsocks, VMess, Trojan, and VLESS are names of different protocols or protocol families, not speed rankings. Make sure your client supports the protocol, configuration format, and subscription conversion method you’re using. If parsing fails, first check whether the format is supported, then make sure you copied the full link. Don’t submit private subscription links to unknown conversion websites.
Which region should I choose? Is a dedicated line always better than a direct connection?
Start with what you need to do, then choose a region. For everyday browsing, prioritize routes that perform reliably on your local network. For streaming or AI services, also check the platform’s regional availability and account rules. A server’s location doesn’t guarantee that a specific catalog or feature will always be available.
A direct connection usually means connecting straight to a server outside your region. A relay adds a forwarding point along the route. An IEPL dedicated line describes one type of dedicated Ethernet connection. These terms describe the network path; they don’t guarantee that the exit IP meets a platform’s requirements or that the transport protocol itself is more secure.
A dedicated line may improve stability on a particular route, but your local network and the load at both the entry and exit points still affect performance. VPNVZ offers coverage in 100+ countries and 170+ routes, but those figures don’t replace choosing the right route for your needs. See the server guide, choose a suitable region, then compare performance under the same conditions.
Connected but can’t open websites? What should I check first?
“Connected” usually means one part of the connection has been established. It doesn’t confirm that your subscription, routing rules, DNS, and destination website are all working. Narrowing down the issue is more useful than repeatedly reinstalling the client.
- ✅ Disconnect and confirm your local network can still reach websites that normally connect directly.
- ✅ Check your dashboard for your plan status, remaining data, and subscription update status.
- ✅ Check the selected route and proxy toggle. Make sure the app you’re testing isn’t bypassing the client.
- ✅ Test the same website on another route, then try other websites on your current route.
- ✅ Check whether other proxy or network tools are running; they may conflict with your routing or DNS settings.
If only domain names fail to load, check DNS. If websites work but one app doesn’t, check whether it follows the system proxy and whether it needs the traffic-routing method specified in the guide. If the issue persists, contact support with your operating system, client version, error message, and the circumstances in which the problem occurs. Hide subscription links and credentials in screenshots.
What does “no logs” mean? Should I worry about DNS leaks?
VPNVZ’s privacy policy is “no logs.” That’s a service policy; it doesn’t mean websites, browsers, payment providers, and devices stop keeping records. A website can still identify your account after you log in, and enabling a network connection won’t clear your browser history.
DNS translates domain names into addresses. A DNS leak generally means a query wasn’t routed through the path you expected and was handled by another resolver, such as one on your local network. This may reveal the domains you looked up, but it doesn’t mean the full contents of webpages are visible.
Set up DNS according to your client’s guide, and check that your browser’s encrypted DNS settings don’t conflict with your routing setup. Treat test results as clues, not proof based solely on the resolver’s location. On public Wi-Fi, check website addresses and encryption indicators. Don’t ignore certificate warnings, and don’t treat a VPN as a replacement for protection against phishing or malware.
How should beginners choose a plan, and what if it’s not a good fit?
If you use the service regularly, stream video often, or work with online files, compare the monthly plans. If you use it occasionally and want unused data to remain available, consider a data add-on. Base your choice on how much you use and how often—not on the number of devices or simply which plan has the largest data allowance.
VPNVZ accepts Alipay, WeChat Pay, and USDT, and offers a 7-day no-questions-asked refund. Check the terms and your dashboard for eligibility and instructions. Keep your order details and submit your request through a support channel. Don’t use a higher-tier plan as a fix for connection problems before confirming that your client is compatible.
For beginners: First confirm that your device can import the configuration. Then check that the websites you need work. Finally, choose a monthly plan or data add-on based on your actual usage.
No device limit addresses how many devices you can use; your data allowance determines how much you can use; your route determines how your traffic travels. Check these separately to figure out whether to adjust your client, switch routes, or choose a different plan.
