FAQ & Troubleshooting

No. VPNDQ only asks for a username and password — that is all it takes to register, with no email verification step. Store both in a password manager, and avoid reusing a combination you have used on other sites.

Simultaneous devices are unlimited. Your home desktop, phone and tablet can sign in to the same account at once — no separate purchase per device, and they will not kick each other offline. Clients cover five platforms (Windows / macOS / iOS / Android / Linux), and the same subscription can be imported on each of them.

Day-to-day route switching does not need a re-import — just pick another node in the client. Only re-copy the subscription when your plan itself changes, such as a renewal refreshing your data allowance or an upgrade to a higher tier. At that point, go back to the user panel, copy the new subscription link once, and run Update Subscription in the client. Most clients can refresh on a schedule, so setting the interval to a few hours removes the manual step.

The format looks like https://example.com/sub?token=YOUR_TOKEN. Copy your real link only from the user panel after signing in, and never use a link from a third-party source.

No. A plan is tied to your account, not to a device. Install the client for that platform on the new device, sign in, import the subscription and you are set — existing devices are unaffected. Simultaneous devices on one account are unlimited, so switching or adding devices never costs extra.

No. Simultaneous devices are unlimited, so several people in one household can share a single account. One thing to keep in mind: every device draws from the same data allowance, so several people streaming HD video at once will use it up faster. If your household uses a lot of data, go straight for the ¥18/month plan with 250GB or the ¥28/month plan with 500GB.

Check four things in order. First, whether the client's system proxy switch is on — some clients connect successfully but only take over traffic once you enable it manually. Second, switch to another route, for example from a direct connection to an IEPL line in Tokyo or Hong Kong. Third, disconnect the VPN and confirm your local network can reach the internet on its own. Fourth, quit the client completely, reopen it and connect again. If only one app fails to load, it is most likely not going through the proxy — see the next answer.

There are three common causes. The app uses its own network stack or forces a direct connection — some banking and payment apps deliberately bypass the system proxy. The client has per-app routing enabled and the app is not on the proxy list. Or the app has cached an old network connection.

Work through it in this order: add the app to the proxy list in the client's per-app routing, force-quit the app and reopen it; if that does not help, try another route. You can also do the reverse and put apps you do not want routed onto the direct list.

This is usually a routing-mode issue. Open the client's per-app routing and add mainland China sites and online-banking apps to the direct list; or switch to rule-based (split) mode, where the client decides by domain which traffic goes through the route and which goes direct. In global mode all traffic passes through the route, which makes verification prompts and slow loading more likely on services inside mainland China.

Start by checking your account: sign in to the user panel and confirm the plan is still active and data remains. Then run Update Subscription manually in the client to rule out an expired subscription. Next, switch routes — Asian routes such as Tokyo and Hong Kong are usually the most stable. Finally, check whether a local firewall or security suite is blocking the client process. If other devices on the same network also cannot connect, try a different network to quickly tell whether the problem is your local network or the client.

Yes. The Windows and macOS clients both have a launch-at-startup switch; when it is on, the client starts with the system and keeps running in the background. Note that launch at startup and auto-connect are two separate switches: the first only starts the program, the second connects to your last used route once it starts. Turn on both and you are online as soon as the system boots. On iOS and Android, allow the client to run in the background in system settings.

Peak hours (roughly 20:00–23:00) are when international links are most congested. Work through it in this order: switch to an IEPL line first (Tokyo, Hong Kong) — dedicated channels avoid the congested nodes of the public internet and hold up better than relay or direct routes at peak times; avoid running large downloads on several devices at once; if you are only watching video, dropping one quality level usually fixes it immediately. Still buffering? Try a node in another city — upstream congestion differs from city to city.

IEPL runs over a point-to-point dedicated channel: low latency and the most stable at peak hours, which suits video calls, live streams and AI tools where stability matters. Relay routes send traffic to a relay node before it goes international — cheaper, and good enough for everyday browsing and video. Direct routes connect straight to overseas nodes; the path is shortest, but performance depends most on the quality of your local connection. For daily use, make IEPL your first choice and keep relay or direct as a backup.

4K sources have a noticeably higher bitrate than 1080p and demand a more stable connection, so leave some headroom on your home broadband and prefer an IEPL line. On data: 4K burns far more per hour than 1080p, so if you mostly watch on a TV or computer, start with the ¥18/month plan with 250GB and only move to the ¥28/month plan with 500GB if your usage is especially heavy. Monthly plan data resets every month on your activation date, and the price difference when you upgrade mid-cycle is prorated over the remaining days.

Work from the biggest factor down. Start with the route — different cities and route types vary a lot at any given moment, so try an IEPL line in Tokyo or Hong Kong first. Then check your local network: are other devices on the same Wi-Fi also slow? Compare against a wired connection. Next, look at device load — background downloads, system updates and heavy tasks on other devices all eat bandwidth. Finally, consider the time of day: peak hours are congested overall, and off-peak is usually noticeably faster. Ruling these out one by one usually pinpoints the bottleneck.

Coverage currently spans 120+ countries / 240+ routes, grouped into Asia, North America, Europe and more. Asian routes (Tokyo, Hong Kong, Seoul, Singapore) are physically closest — first choice for everyday browsing, video calls and AI tools. North American routes (Los Angeles, Toronto) suit US-region streaming and services. European routes (Frankfurt, London) cover European content. The same city often offers both IEPL and relay types, distinguished in the client by route-type labels.

Three: Alipay, WeChat Pay and USDT. After placing an order, pick the channel on the payment page and pay; once payment succeeds the order status updates automatically and the plan takes effect right away — no manual confirmation.

VPNDQ offers a 7-day money-back guarantee. Submit a refund request through a ticket in the user panel and include your order number; once processed, the money goes back to the original payment method. After that window, no-reason refunds are no longer available; if you are hitting a service-quality issue such as a route failure, you can still report it by ticket and support will help.

Monthly plan data resets every month on your activation date. Sign up on the 15th, for example, and your allowance is topped back up on the 15th of every month — unused data does not roll over. If you upgrade to a higher tier mid-cycle, the price difference is prorated over the remaining days and the new plan's allowance applies.

A monthly plan gives you a fixed amount of data each month (¥9.9/month for 60GB, ¥18/month for 250GB, ¥28/month for 500GB) and resets on your activation date — best for steady, long-term use. A data pack is a one-off allowance that lasts until it runs out and never expires (¥158/300GB, ¥358/1000GB, ¥658/3000GB) — best when your usage varies or you only need a lot of data at certain times. For long-term use a monthly plan works out better; for occasional heavy months, a data pack covers it.

When a monthly plan expires the client disconnects, but your account, order history and any unused data packs are kept. After renewing, go back to the user panel, copy the subscription once more and update it in the client to get back online.
