Account, connection and billing FAQ

No. A username and a password are all it takes — no email address required. Your username is the only credential for signing in and recovering your account, so memorize it or store it somewhere safe. Once registered, sign in to the user panel; your subscription and orders all sit under that one account.

As many as you like. Windows, macOS, iOS, Android and Linux can all sign in to the same account and stay online — there is no need to buy a second subscription for a second device. With many devices, split them by purpose: desktops for long-lived office work and AI tools, mobile for streaming.

No need to buy again. The subscription is tied to your account: sign in to the user panel and open the downloads page to get the client and the subscription link. When you switch clients or devices, just import the same subscription link in the new client; signing out on the old device does not affect the new one.

First check that no characters were dropped when copying the subscription link — it is long, so copy the whole string. Then check that your client version supports the import method shown in the panel. If the client reports a successful subscription update but the list is still empty, tap update subscription once manually in the client, or delete the profile and import it again.

The sign-in page has a recovery entry — follow the on-screen steps to verify and reset your password. Because registration does not collect an email address, self-service recovery may not always work; in that case open a ticket through the support link in the footer and include your username and the date of your most recent order so it can be checked and handled.

Work through it in order: first check whether the client is in rule mode or global mode — in rule mode, domains that match no rule go direct; second, try another site to rule out a problem with that one site; third, switch to another server and reconnect; fourth, restart the client to flush the DNS cache. If all four steps fail, note the server name and the error message and open a ticket.

The usual cause is that the app uses its own network stack or UDP transport, and rule mode does not route it through the proxy. You can add the app to the proxy list in the client, or switch to global mode temporarily to confirm; once you know it is a rule issue, switch back to rule mode so other apps on your local network are not affected.

Check in turn: whether the system clock is accurate — a time offset makes the encrypted handshake fail; whether another proxy or security tool is also taking over the network; try another server or another protocol; on Android, also add the client to the battery optimization allowlist so the system does not kill it in the background. If it still drops after all that, note the time and the server name and open a ticket.

First confirm your local network works — can you open an ordinary website without the proxy? Then try another server. Switching networks, for example from Wi-Fi to mobile data, often gets around handshake problems on the carrier side; on Wi-Fi you can restart the router. If only one server hangs while the others are fine, just switch servers.

That is the normal system flow. iOS and macOS need permission to add a VPN configuration, Android needs VPN permission, and Windows and Linux need permission for the client to create a virtual network adapter. If you decline, the client cannot take over traffic — reopen the client and accept again.

Change the server type first, then the region. A region usually has several servers: dedicated lines are the most stable at peak hours, relayed lines next, and direct lines depend most on local exit quality. If only one app is slow after switching, a video site for example, the bottleneck is the destination site rather than the server — changing region usually helps more than changing server.

Dedicated lines use a private path with the lowest latency and jitter, suited to video calls and long-lived tools; relayed lines forward through an intermediate node, with price and stability in between, suited to everyday browsing and streaming; direct lines land straight on the target region's exit, the shortest path, but are the most sensitive to local network quality. Every server in the list is labeled with its type — pick by purpose.

Choose by purpose, not by how popular a region is. Video calls and remote work go to dedicated lines first, where low jitter matters; streaming goes to servers labeled for that platform; AI tools and code-completion tools go to servers with stable long connections. Once chosen, keep that server fixed rather than switching often — the connection state cached by the client stays steadier.

A speed test only reflects throughput at that moment; real experience is also affected by Wi-Fi signal, local bandwidth, how many devices are online at once and rate limits on the destination site. The more reliable way to judge a server is to compare the same app over the same stretch of time, not to look at a single speed test number.

Plans are billed by data allowance, and monthly plan data resets every month on your activation date. When the allowance runs out you can buy a data add-on in the panel to top up; add-ons last until used and never expire. If things only slow down at certain times, switch servers in the order above first — most cases are server congestion rather than an allowance issue.

Three: ¥9.9/month with 60GB, ¥18/month with 250GB, ¥28/month with 500GB. Data resets monthly on your activation date, not on the calendar month; if you activated on the 12th, it resets on the 12th of each month.

Two options: buy a data add-on — ¥158/300GB, ¥358/1000GB, ¥658/3000GB, valid until used and never expiring — or upgrade your monthly plan to a higher tier in the panel. Upgrades are prorated by the price difference over the remaining days, so you do not have to wait for the next reset date.

The price difference is prorated over the remaining days. After upgrading, the higher tier's data allowance applies immediately, the remaining days in the current period are counted at the new tier, and data already used is not reset. The upgrade entry is in the plan section of the user panel, with the same payment methods as at purchase.

A 60-day no-questions-asked refund is available. Open a ticket in the user panel with your username and order number; the refund goes back to the original payment channel. You can find the order number in the order list in the panel.

Three: Alipay, WeChat and USDT. After ordering, choose the method on the payment page to complete payment; the order status updates in the panel. If payment succeeded but the order has not turned paid, refresh the panel first, and if it still has not updated, open a ticket with the payment receipt.
