Usually no. Sanmao VPN provides one-tap apps. If you already use v2rayN, Shadowrocket or v2rayNG, you can also follow the guide and import subscription details.

Device limits depend on the plan. Starter plans fit personal phone-and-desktop use, while higher plans are better for families, tablets and work devices.

Sanmao VPN combines apps, route recommendations, subscriptions and support into one service. It is tuned for China VPN scenarios, while tools such as LVCHA VPN or generic proxy apps may require more manual adjustment.

Refresh the subscription, switch to a recommended route and confirm your device time is correct. If the issue remains, contact support with your device, network and error details.

Yes. Overseas users can select routes for domestic or international services, including study, work, entertainment and temporary research needs.

Click 'Forgot Password' on the login page and verify your registered email to reset the password.

Yes. Campus networks, libraries, cafes and hotels can have access limits or security risks. Sanmao VPN encrypts traffic and helps protect logins on shared networks.

Your ISP should not see the specific pages, accounts or content inside the encrypted connection. It may only see that encrypted traffic is being transmitted.

No. We do not build long-term browsing histories, download records or real-IP behavior profiles. Necessary operational data is limited to service security and troubleshooting.

No VPN Provider can honestly promise permanent access under every condition. Sanmao VPN uses obfuscation and dedicated routing to improve resilience, and support can recommend alternate routes during disruptions.

The apps use modern encrypted protocols and secure routing controls to reduce exposure on public Wi-Fi, mobile data and shared networks.

After a normal connection, websites should see the Sanmao VPN exit node rather than your local network IP. You can verify this with an IP checker.

Yes. Kill Switch behavior helps prevent traffic from falling back to an unencrypted network if the VPN connection unexpectedly drops.

DNS requests are routed through the encrypted channel whenever possible, reducing hijacking, pollution and forced redirect issues.

Some routes support P2P use. Check node notes before use and follow local laws and platform rules.

Free routes can be affected by simultaneous demand. VIP dedicated routes have higher priority and are better for scheduled meetings, HD streaming and large file transfer.

Split tunneling lets local apps use the direct network while global services use the VPN route. WeChat or local payments stay local, while Google, YouTube and ChatGPT use encrypted routing.

Some routes include basic filtering rules to reduce pop-ups and malicious redirects, but they do not replace browser security extensions or device protection.

Yes. Connection failures, app installation, subscriptions and route selection can be handled through tickets or Telegram support.

Airport services often focus on cheap nodes and manual subscriptions. Sanmao VPN is VPN-first, with apps, privacy language, account management and support built into the product.

Free airport nodes can be useful for quick tests, but stability and responsibility are often unclear. Sanmao VPN is designed for users who need repeatable access and support.
