No. Signing up only takes a username and password — no email address and no extra verification documents. Your username and password are the only credentials for the account, so use a password you don't use anywhere else and keep it safe.

If you forget your password, follow the prompts on the recovery link on the panel login page; if that doesn't work, open a ticket with the username you registered with and the team will verify it manually.

As many as you like. One account works on Windows, macOS, iOS, Android and Linux at the same time — there's no need to buy a second subscription for a second device.

Data is counted per account, so every device draws on the same plan allowance; the more devices you run, the faster it goes. For long-term use across several devices, the ¥18/month plan with 250GB or the ¥28/month plan with 500GB is the better fit.

Sign in to the panel, copy the subscription link from the overview page, then open your client and choose "Import from clipboard" or "Add subscription" and paste it in. The client pulls the route list after import; pull down to refresh to get the latest nodes.

A subscription link works like an account credential, so don't post it in public groups or share it as a screenshot. Example addresses in the guides are always fake, e.g. https://example.com/sub?token=YOUR_TOKEN — don't copy them.

No. Install the client on the new device and import the same subscription link — your remaining data and expiry date stay with the account.

There's no need to back up the client configuration before reinstalling; the subscription link is the thing to keep. If the client on the old device is still running, disconnect it before connecting the new one, so it's easier to tell which side a problem comes from.

Sign in to the panel and reset the subscription address; the old link stops working immediately, then re-import the new link on each device. Every device needs one update after a reset — that's expected.

Don't paste subscription links into public repos, forums or chat groups; when you need to show someone, take a screenshot with the token covered.

Four steps. First, pull down to refresh the subscription in the client and confirm the route list isn't empty. Second, set the system clock to sync automatically — VLESS and Trojan are sensitive to clock drift and a few minutes off can break the handshake. Third, switch to another route to rule out a single bad one. Fourth, turn the proxy off and connect directly to confirm your local network is fine.

If all four check out and it still won't connect, try another protocol or open a ticket.

Usually the routing rules don't cover that app. Add it to the proxy list in the client's rules or per-app proxy settings, or switch to global mode temporarily to test — if it works in global mode, the rules are the problem, not the route.

Apps that need UDP (some voice chat, games, video calls) also need a protocol that supports UDP, such as Hysteria2 or TUIC; on TCP-only protocols those apps won't connect.

Check the system clock first — clock drift is the most common cause of certificate validation failures. Next, confirm the client isn't running both TUN mode and the system proxy at once; the two compete for traffic. Then check whether security software is intercepting HTTPS.

If the error persists after ruling those out, try another route and another protocol once each — that tells you whether the problem is on the route side or on your machine.

Usually the Wi-Fi network itself is restricted: an office or hotel gateway that only allows web ports, or blocks UDP. Switching to a TCP-based protocol often gets through.

If it still fails, test with a phone hotspot — if the hotspot works, the router's policy is the cause, so change networks rather than keep tweaking client settings.

It means traffic is being routed to an overseas exit by the rules. Check whether the client has been switched to global mode; switch back to rule mode, where mainland China addresses go direct by default.

If it only happens on a few sites, those sites probably use an overseas CDN — that's normal, and you can add a direct rule for them without affecting other traffic.

Five: Windows, macOS, iOS, Android and Linux. Sign in to the panel, open the download page, pick the client for your system, then go back to the overview page, copy the subscription link and import it.

Routers, TV boxes and other devices outside those five platforms aren't officially supported — no availability guarantee is made for them, and buying a plan specifically for them isn't recommended.

The order of preference is IEPL dedicated line, relay, then direct. Dedicated lines run on separate capacity and are least affected by congestion on public links at peak hours; relays are optimised on the cross-border segment and offer good value; direct routes cost the least and fluctuate the most when links are congested.

When a region has several routes, switch through them one at a time for a minute or two each, note the stable one and stick with it — less hassle than picking at random every time.

4K bitrates are well above 1080p, so both bandwidth and stability matter more; stuttering is usually jitter and packet loss rather than a lack of peak bandwidth.

Before watching, pick a dedicated line, switch to a protocol with better UDP support and avoid the busiest peak-hour window. If it keeps buffering mid-play, switching to another route in the same region usually helps more than reconnecting over and over.

Cross-border speed depends on three segments: your local network to the ISP exit, the cross-border segment, and the overseas exit to the target site. Changing networks changes the first segment, and ISPs differ in peering quality, so results differ too.

Mobile data and home broadband use different exits, so a clear gap on the same route is normal — judge by the measurements on the network you actually use.

For latency-sensitive work, mostly browsing and office tasks, choose VLESS or Trojan — fast handshakes and low overhead. If you often need UDP, choose Hysteria2 or TUIC. For older devices where compatibility comes first, VMess is the safer pick.

Faster isn't always better: route quality usually matters more than the differences between protocols, so get the route right first, then fine-tune the protocol. More detail is on the technical reference page.

Monthly plan data resets every month on your activation date and comes back automatically at the start of the next cycle. If you use it up early, you can buy a data pack and keep going — packs last until used up and never expire; or upgrade to a higher monthly plan, with the difference prorated by remaining days.

Both balances sit in the same account, and the panel shows each remaining amount separately.

Three tiers: ¥9.9/month with 60GB, ¥18/month with 250GB and ¥28/month with 500GB. Data resets monthly on your activation date, not on the calendar month; if you upgrade mid-cycle, the difference is prorated by remaining days.

Per gigabyte, the ¥28 tier is the best value; for light use — the occasional lookup or file transfer — the ¥9.9 tier is usually enough. See the pricing page for the full comparison.

A monthly plan is billed by the month and its data resets monthly on your activation date, which suits long-term use. A data pack is a one-off purchase that lasts until used up and never expires, which suits short business trips, temporary projects or topping up a monthly allowance.

Three data packs: ¥158/300GB, ¥358/1000GB and ¥658/3000GB. Both share the same account, so there's no separate login.

The difference is prorated by remaining days, and you aren't charged twice for the part of the cycle you've already used. Upgrades are done in the panel; once you pay the difference, the new plan takes effect in the current cycle, and the panel shows the data available for that cycle.

For example, upgrading from the ¥9.9 tier to the ¥18 tier mid-cycle only costs the difference for the remaining days, not another full month.

A 7-day no-questions-asked refund is available. To request one, open a ticket in the panel with your order number and the reason; once it's verified, the money goes back to the original payment method.

No-questions-asked refunds aren't accepted after 7 days; the full terms are on the terms page, and that page is authoritative.

Three: Alipay, WeChat and USDT. Choose one at checkout after placing the order, and the order status appears in the panel once payment completes.

USDT is an on-chain transfer that needs block confirmations, so an order showing as pending during that time is normal; orders left unpaid for a long time may close automatically — just place a new one.
