How to Use a VPN: Common Questions for First-Time Users

Getting Started: How Do the Client and Subscription Link Work Together?

The dashboard manages your account, plan, and configuration; the client establishes a connection on your device. They are not the same thing: signing in to the dashboard does not mean a proxy is active on your device, and installing a client does not mean it already has a working route. VPNZS does not require an email address; you can register with a username and password. Once in the dashboard, follow the instructions for your device.

A subscription link is usually how a client retrieves node configuration, not a regular webpage to browse directly. Clients that support subscription imports read the link and create a route list. To update it later, retrieve the list again. Do not share the link in public forums or post screenshots that show the full link in public help threads; it may contain account-specific credentials.

1. Choose the version for your operating system from the client download page in the dashboard, then read the instructions for your platform.
2. Get the configuration as directed in the dashboard. If you are asked to import a subscription, look for “Subscription,” “Configuration,” or “Import” in the client; labels vary between apps.
3. After importing, check that a route list appears. If it is empty, first check that the link is complete and the subscription updated successfully. Do not repeatedly click Connect.
4. Choose a route and connect. Allow any necessary network permissions requested by your operating system, then visit the sites or tools you need.
5. Confirm that the target service works, check that your usual local sites still work, and then review your data records in the dashboard.

If an import fails, first check that the client supports the protocols and formats in the configuration. Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols; similar names do not mean their configurations are interchangeable. These are general examples, not a claim that VPNZS offers all of them. Check the dashboard for the protocols and clients currently supported.

“Subscription” commonly has two meanings: a monthly subscription is a billing method, while a subscription link retrieves configuration. Updating a configuration link does not renew your plan or restart its billing cycle.

Can You Use Multiple Devices at the Same Time?

VPNZS has no device limit, so you can configure and use it on your own devices. Supported platforms include Windows, macOS, iOS, Android, and Linux. But “no device limit” does not mean each device gets its own separate data allowance: check the total data records for your account in the dashboard rather than treating device count as a way to multiply your data.

Connection options and permission prompts vary by platform. Windows and macOS commonly offer system proxy and virtual network interface modes. Mobile operating systems usually use system VPN permissions to manage network traffic. Linux steps depend on the specific client and desktop environment. Seeing a VPN icon in the system tray does not mean the connection necessarily uses the same traditional VPN protocol in every case.

If a browser works but other apps do not, those apps may not follow the system proxy settings. Clients with TUN mode can handle more traffic through a virtual network interface, but may need additional permissions and can conflict with other network tools. Check the current client documentation first, and do not turn on multiple proxy or VPN tools at once to “stack” acceleration.

When troubleshooting across devices, first connect only the device that has the problem. If another device works on the same network and route, focus on the affected device’s permissions, rules, and configuration. If both have problems, check the local network and selected route. This makes it easier to identify the cause than changing settings on every device at once.

How Is Data Measured, and Which Plan Should You Choose?

Data allowance is not connection time. Staying connected without transferring data uses a different amount from continuously streaming video. Video, file downloads, and cloud storage sync usually use more data than text browsing. Check the dashboard for how uploads, downloads, and protocol overhead are counted; do not estimate final usage from a downloaded file’s size alone.

Monthly data resets on your activation date, not at the start of each calendar month. If you upgrade a monthly subscription mid-cycle, the price difference is prorated by the remaining days; check the dashboard for the exact calculation. “Never expires” refers to the validity of unused data, not a promise that every site or route will always be available.

If you are unsure how much data you need, review your actual usage before changing plans. Pay particular attention to background sync, app updates, and autoplay video; closing a browser tab does not necessarily stop apps running in the background from transferring data. Check the plans page for full pricing. Payment methods include Alipay, WeChat Pay, and USDT.

Will Your Speed Be Limited? Do More Routes Always Mean Faster Connections?

Data allowance alone cannot tell you whether your speed is limited. An allowance describes how much data you can use; speed also depends on your local network, route load, transmission path, and target service. No fixed speed or speed-limit threshold is specified, so “no device limit” should not be read as unlimited speed, and route names are not speed guarantees.

VPNZS covers 120+ countries and offers 250+ routes. These figures describe the range of choices, not how every route will perform for every user. A nearby region can be a useful starting point, but distance is only one factor. The path from your local carrier to a node and the path from the node’s exit to the target site also matter.

What Is the Difference Between IEPL, Relay, and Direct Connections?

IEPL usually refers to an international Ethernet private line service provided by a carrier. However, a “dedicated line” label in a product should be understood in the context of its actual routing description; it does not automatically mean there is a dedicated line all the way from your device to the target site. A relay usually forwards traffic from an entry node to an exit node, while a direct connection usually connects your device straight to a node outside China. Different routing structures do not mean one option will always be faster.

When evaluating a route, testing your actual tasks is more useful than looking at latency alone. For meetings, check for audio dropouts and frozen video; for webpages, check that they load fully; for file transfers, check that they continue steadily. Compare routes one at a time on the same network and with the same target service. Keep your existing rules unchanged while switching, so you do not mix several changes together. Check the current dashboard list for the specific route types available.

Do You Need to Stay Connected? Start with Routing Rules

You do not have to stay connected just to “keep things working.” Connecting only when you use an app that needs the route is perfectly normal. If you need long sessions for collaboration or continuous transfers, you can stay connected. Battery use on mobile devices depends on the client, signal, and background traffic; no client can guarantee that staying connected will have no effect on battery life.

Rule-based mode usually decides whether traffic goes through a proxy or connects directly based on domains, addresses, or app conditions. It can be useful when you need both international sites and local services. Global mode usually routes all traffic the client can handle through the proxy, but may not cover every process on your device. Direct mode usually bypasses the proxy; the exact meaning of these labels varies by client, so check its documentation.

Global mode can help determine whether a problem comes from routing rules, but it is not a good long-term fix for every issue. If an app fails in rule-based mode but works in global mode, check the relevant domain or app rule. If both modes fail, continue checking the route, target site, or local network.

Before accessing payment services, company systems, or region-sensitive services, confirm the exit region and relevant requirements. Avoid changing regions during an important active session; a change of exit may prompt the platform to verify your login again.

Connected but Nothing Loads: How to Troubleshoot

“Connected” usually means the client has established some form of connection; it does not guarantee that the target site, DNS resolution, or app proxy is working properly. First identify whether all sites fail, only one site fails, or only one app fails. The scope of the issue points to different troubleshooting steps.

• ✅ Pause the proxy and check that your local network works. If the underlying connection is down, troubleshoot your Wi-Fi or carrier connection first.
• ✅ Check your plan status, remaining data, and configuration update results to make sure you are not using an outdated or invalid configuration.
• ✅ Try another route with the same target and check whether only the original route has a problem. Avoid changing several settings at once.
• ✅ Check system proxy or TUN permissions, and see whether other network tools are still handling traffic.
• ✅ Compare rule-based and global modes to find out whether the target request is being routed incorrectly.
• ✅ If the issue persists, note your operating system, client, route name, and error message, then submit a ticket through the dashboard. Hide your subscription link and account credentials before sharing screenshots.

DNS converts domain names into addresses, and resolution problems can make some sites fail to load. A DNS leak occurs when queries expected to use a particular resolution path take an unintended route—for example, when they are still handled by your local network. It does not mean all browsing content has been exposed, and a page loading successfully is not enough to confirm there is no issue.

To troubleshoot DNS, first check whether the client offers the relevant DNS handling setting and whether it is enabled. A browser’s encrypted DNS feature can also change the resolution path. Follow the client documentation rather than blindly copying DNS addresses from online sources. VPNZS describes its security approach as quantum encryption, but this does not replace device updates, account protection, or correct routing settings.

First Time Using a VPN: How Can You Tell If It’s a Good Fit?

Do not test just one webpage. Try your usual collaboration tools, video services, and local sites. Check for interruptions during your normal usage hours, then see whether the data consumed in the dashboard matches your expectations. The target platform’s regional policies, account permissions, and service issues can also affect results; a working connection does not mean every platform will make all content available.

If you run into a service issue, contact support through dashboard tickets and describe the checks you have already tried. For client instructions, continue with the getting started guide or help center. Avoid reporting only “it doesn’t work” without including steps to reproduce the issue.

VPNZS offers a 60-day no-questions-asked refund: “A full refund may be requested within 60 days of the first payment.” This is a refund policy, not a guarantee of connection performance. To request a refund, submit a ticket through the dashboard. The request period after the first payment does not restart with each renewal.
