VPN beginners often have questions about billing, apps, and server settings. Start by distinguishing your account, plan, subscription link, and connection status; then troubleshoot the specific issue. Here are answers to 10 questions in the order you’re likely to encounter them. VPNJK pricing and policies are explained separately from general information about how VPN apps work.

How do I get the app and connect after creating an account?

VPNJK doesn’t require an email address. Create an account with a username and password. Your account manages your plan, data, and support tickets; it doesn’t mean a device is already connected. The client is software installed on your device, while the subscription link provides server settings to the client. Each step is separate.

VPNJK supports Windows, macOS, iOS, Android, and Linux. Sign in to the dashboard and make sure you have an active plan to access downloads and your subscription. Permission prompts, import options, and background behavior vary by operating system. Don’t look for a button using the name shown on another platform; follow the relevant platform’s setup guide.

  1. Sign in to the dashboard and check your plan status and remaining data, then open the client download page.
  2. Get the client and subscription for your operating system, then import the link using the client’s subscription or configuration option.
  3. Update the subscription, check that the server list appears, then choose a server and connect.
  4. Grant network configuration permissions when prompted, then visit a website to verify the connection. Don’t rely on the toggle changing color as proof that it worked.

A subscription link may contain access credentials, so protect it like a password. Don’t post the full link in public forums when asking for help, and never include your account password alongside the subscription in a screenshot.

Can I use a computer and other devices at the same time?

Yes. VPNJK doesn’t limit the number of devices you can use at once. That doesn’t mean data is unlimited or that each device gets a separate data allowance. Devices on the same account share the data included with its plan, so consider your overall usage across devices when deciding whether it’s enough.

You still need to install the client, import the subscription, and connect on each device. Connecting successfully on a computer won’t connect your other devices automatically. Proxy modes, system permissions, and routing rules can also vary between devices. If the same subscription works differently on different devices, check the local settings before assuming there’s an account problem.

To make troubleshooting easier, connect and test access on one device before setting up the others. Don’t treat “no device limit” as permission to share your account publicly; shared credentials make data use, configuration changes, and account management harder to track.

How is data used, and when does it reset?

Web browsing, video, file transfers, and background app requests can all use data. A page that appears idle doesn’t mean an app has stopped connecting; cloud sync, preloading, and background updates may continue to transfer data. Whether a request goes through this service depends on the client mode, routing rules, and system settings.

VPNJK monthly plan data resets each month on the day you activated the plan, not at the start of each calendar month. Check your plan details in the dashboard for your remaining data and reset date. The client’s local usage counter and the service’s usage records may differ in what they measure or when they update, so don’t assume they’ll match exactly.

Data bundles remain valid until used up and never expire; their allowance doesn’t refresh monthly. If data use seems higher than expected, temporarily turn off unnecessary background transfers, check which apps are running, and review the dashboard records. The available information doesn’t specify how uploads, downloads, or other usage are measured, so ask support about specific discrepancies rather than assuming how the calculation works.

How do I choose between a monthly plan and a data bundle?

First consider how regularly you use the service and whether your usage is concentrated. If you frequently visit international websites, work online, or stream video, compare your needs with the monthly plan allowances. For occasional use, or if you don’t want unused data to reset periodically, consider a data bundle that never expires. Choose based on how you use it, not on which plan name sounds bigger.

Monthly plan and data bundle pricing and allowances
Billing option Price and data Allowance rules How to choose
Monthly plan ¥9.9/month includes 60GB
¥18/month includes 250GB
¥28/month includes 500GB
Resets monthly on the activation date For regular use; choose an allowance based on your monthly needs
Data bundle ¥158/300GB
¥358/1000GB
¥658/3000GB
Valid until used; never expires For occasional use; choose an allowance based on your total needs

If you upgrade a monthly plan partway through its billing period, the price difference is prorated for the remaining days. Don’t assume an upgrade starts a new, full billing period; check the order details in your dashboard first. Also, don’t assume which plan is charged first if you have both a data bundle and a monthly plan. Check the dashboard or ask support for the applicable rules.

Does the client need to stay connected all the time?

You don’t need to stay connected to keep your account or plan active. Apps that need the VPN connection may stop working when you disconnect or switch back to your device’s regular network. Whether to stay connected depends on what you’re doing and how your apps behave.

Also distinguish between closing a window, quitting the client, and disconnecting. A desktop client may keep running in the background after its window closes, and network settings on mobile devices may remain active. When you’re done, check the connection status in the client rather than just looking for an open window.

Running the client continuously may use more battery, depending on your operating system and app activity. If you use split tunneling, staying connected doesn’t mean all your traffic goes through the server. Disconnect when you’re done. For tasks that need a consistent network location, avoid repeatedly connecting, disconnecting, or switching servers mid-session.

How do I switch servers, and what’s the difference between locations and server types?

In the client, choose a server from the server list or proxy group, then try connecting again. Existing connections may not move to the new server immediately; you may need to close and reopen the app you’re using. If the server list is empty or missing an expected option, update the subscription and make sure the client isn’t still using an older configuration.

A server location determines where your traffic exits; the server type describes its network path. IEPL uses a dedicated link. A relay server forwards traffic through an intermediary server, while a direct connection typically connects from your local network to an international entry point. Performance also depends on your local ISP, the entry and exit points, and the destination website. A server type alone doesn’t guarantee a particular speed.

VPNJK covers 100+ countries and offers 220+ routes. When reviewing the server guide, consider both your destination and the server type rather than choosing based only on the number of listings. For apps that are sensitive to location, keep your exit location consistent and follow the platform’s rules. Changing locations doesn’t guarantee access eligibility.

What’s the difference between rule mode, global mode, and TUN?

Rule mode uses domain names, addresses, or other matching criteria to decide whether requests connect directly, use a proxy, or are blocked. It’s useful for routing different kinds of traffic separately. Global mode generally sends requests handled by the client through the selected proxy; it doesn’t automatically cover every app on your device. This is a common point of confusion for beginners.

System proxy settings affect apps that follow them, but some apps use their own network settings. TUN mode routes traffic through a virtual network interface and usually covers more traffic, but its scope still depends on the client, routing, exclusion rules, and system permissions. Don’t assume that turning on TUN means everything is configured correctly.

Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols or implementations, not alternative names for these modes. The subscription format, protocol support, and required settings must match the client. Use the configuration provided in the VPNJK dashboard; don’t change the transport method or credentials based on a protocol name alone.

What is a DNS leak, and how can I check for one?

DNS translates domain names into network addresses. A DNS leak generally means a lookup that was expected to use a particular route instead went to a different DNS service or used another network path. Seeing the expected exit IP on a website isn’t enough to confirm that DNS requests followed the same route.

Check the client’s DNS settings, your browser’s Secure DNS setting, system network settings, and routing rules together. A browser may use its own DNS service, and some rules may intentionally send certain domains directly. If a test shows a local resolver, don’t draw conclusions without considering your current mode and settings.

If your configuration came from the dashboard, keep its associated settings and check them against the setup guide first. After making changes, test the destination website again and confirm that local websites still work. Encryption, DNS routing, and how a website identifies your account are separate issues; checking one doesn’t replace checking the others.

Connected, but websites won’t load. What should I do?

“Connected” may only mean that the client is running or a system network interface has been established. It doesn’t necessarily mean the selected server can communicate with the destination website. Start by checking how widespread the issue is: if all websites fail, check your local network and client first; if only one site fails, check the routing rules, server location, and the site’s restrictions.

  • ✅ Disconnect and confirm your device’s regular network can still access everyday websites, ruling out a local internet outage.
  • ✅ Check your plan status and remaining data in the dashboard, then update the subscription and confirm that the configuration loaded successfully.
  • ✅ Check the selected server and routing group. The connection may be on while requests to the destination are still going direct.
  • ✅ Check whether other proxy tools or network-routing apps are running and overriding the settings.
  • ✅ Switch to a server suited to the destination’s location and test again. Keep any error messages to help support diagnose the issue.

Change one setting at a time and record the results before and after. Don’t reinstall the client, change DNS, and switch modes all at once; even if access returns, you won’t know what fixed it. Logs may contain subscription links, account identifiers, or credentials, so redact sensitive details before sharing them.

How do I request a refund, and what should I include when asking for help?

VPNJK offers a 14-day no-questions-asked refund. The policy allows a full refund on request within 14 days of your first payment. Before applying, read the support information and check the date of your first payment. The client installation date or your most recent connection date doesn’t start the refund period.

Sign in to the dashboard and use the support ticket page to explain your refund request and provide the relevant order details. VPNJK supports Alipay, WeChat Pay, and USDT. Ask support to confirm refund processing details and status; don’t assume how long different payment methods take to settle.

If you’d like help troubleshooting first, include your operating system, client name, selected server, error message, and steps you’ve already tried. Describing which websites work and which don’t is more helpful than simply saying “it won’t connect.” A refund request and a technical support request are separate issues, so state clearly which one you need help with.

VPN basics: Check that your plan is active, import the subscription, and verify access to your destination. If you share data across devices, keep an eye on overall usage. Compare monthly plans and data bundles based on whether you use the service regularly or occasionally. For connection issues, check your local network, plan, configuration, server, and destination site in that order instead of changing settings at random.
