How to Reach Us and Never Lose Contact

• QQ group: the only channel that opens directly inside China before any route is connected; anyone with a phone-registered QQ account has it. Mention @海绵宝宝 for the AI to answer; files and screenshots are easy to share. The platform filters content, so never post configuration files or QR codes there.
• Telegram group: first choice for overseas Chinese and students. You can show only a username, messages and files are not filtered, and the AI answers without being mentioned. Inside China, turn on a route (or the web proxy) first, then open it.
• Discord: convenient for overseas users and gamers who already live there; post in the channel and someone answers, no mention needed. As with Telegram, inside China turn on a route first, and the Android package is a split APK — see below.
• If you only want one: inside China join QQ first and add Telegram once the route works; abroad, join Telegram. The AI agent and the humans are the same across all three, so a question never needs repeating.

1. Open the contact page (“Contact” in the navigation). The three cards at the top are the group QR codes — scan on a phone or tap the QR code to join (each card says “Tap the QR code to join”); the SpongeBob in the bottom-right corner of every page also jumps straight here.
2. Without Telegram or Discord installed, the Download center on the contact page serves the installers for Windows, macOS and Android directly from this site (Linux gets a one-click Flathub install of the official package), reachable inside China. The Telegram Android package is the official full APK.
3. Discord for Android is a split package (arm64 phones only) that the system installer cannot open: install the open-source SAI (Split APKs Installer, linked in the Discord item) first, then open the .apks file with SAI.
4. iPhone and iPad can only use the App Store; if the China store does not list Telegram or Discord, you need a non-China Apple ID — the same method as for Hiddify and Tailscale.
5. After joining, try a simple “hello”; the AI agent will respond. In the QQ group remember to mention @海绵宝宝.

SpongeBob is online 24 hours and answers “how do I use the service” questions: troubleshooting a failed connection, which region to pick, which connection method suits your network, claiming the trial, pricing and points, flashing and binding a router, the refund policy. It answers from our knowledge base, and its numbers come from there; when unsure it tells you and asks you to mention the owner.

Ask a human for: processing a refund, a payment that has not arrived, duplicate charges, router shipping and logistics, a banned account or authentication failure, a binding conflict. These need back-office access or handle money and goods, so a human handles them: mention the owner in the group, email support, or use the human support QQ in the second row of the contact page.

Include these four things and most problems are located on the first reply: the connection method (private network / Cisco / OpenVPN / proxy / Hiddify / router), the region, the error text or a screenshot, and the exact time it happened.

• The support email is in the second row of the contact page and every message gets a reply. Suited to anyone who prefers not to join a group, or to private matters involving the account or payments.
• The human support QQ is in the same row and also always answers.
• System emails: a reminder 24 hours before expiry, and after expiry a win-back email with a one-time claim button. The sending domain is ours and the button is safe to click; if nothing arrives, check spam and the promotions tab.

1. Memorise the four domains and their order: leotun.com → 7d24hrs.com → 7x24btc.com → anyfq.com. Identical content, one account; if one fails, try the next. Save them as bookmarks or a note.
2. Join at least one group. When a domain is blocked, the new address appears in the groups first, and group invite links and QR codes do not depend on the site domain. Inside China the QQ group opens without any route — the last-resort fallback.
3. Install and log in to a client now. Route addresses rotate automatically, so a blocked website never stops an already-configured client from connecting; connect first, then open the site.
4. Keep your registered email valid and add the support address to your contacts or allow-list. Expiry reminders, win-back emails and trial codes arrive there, and domain changes are announced by email too.
5. The six public knowledge repos on GitHub (linked at the end of the guides section and inside the articles) carry the current site address and group entry points at the top of each README; GitHub opens on most networks inside China, so it is another route.
6. When recommending us, give www.leotun.com — the domain reserved for introductions. If it gets blocked we switch mirrors and existing users are unaffected.

• The official groups are only the ones on the contact page. Any “LeoTun group” or “support DM” found elsewhere is not us.
• The owner and support staff never DM you asking for passwords, verification codes or payments, and refunds never require your payment password.
• Never post configuration files, QR codes or subscription links in a group — they are your account. In screenshots for support, blur addresses and tokens.
