📱 Can I use the same account on multiple devices?
Yes, you can log into multiple devices using the same account.
Note:
Each online device will occupy one connection slot.
If you want to use the VPN on multiple devices simultaneously, you need to purchase additional connections.
🌍 How to choose the best server node?
We recommend selecting nodes marked with "China Transit Line" or "Dedicated Line" — these are high-speed, stable channels optimized for users in China.
Simply choose the server node based on your needs (e.g., Japan, USA, Hong Kong, etc.).
❌ VPN not connecting? Try the following steps:
-
Restart the VPN client
-
Switch to a different server node
-
Restart your Wi-Fi router

🌐 Web Proxy Mode vs. Client Mode
🔹 Web Proxy Mode:
-
Only works with Google Chrome
-
Proxy only applies to websites opened in Chrome
-
Other browsers and apps won’t use the VPN
🔹 Client Mode:
-
Routes all apps and browsers (Chrome, Edge, Safari, etc.) through the VPN
-
More comprehensive and secure
🌐 Global Mode vs. Partial Mode
🔹 Global Mode:
-
All network traffic goes through the VPN
-
Best for maximum privacy protection
-
You can manually exclude certain IPs or regions (e.g., local apps or websites)
🔹 Partial Mode:
-
By default, traffic does NOT go through VPN
-
Only specific websites or IP ranges you set will use the VPN
-
Ideal for accessing specific overseas content (e.g., streaming services)
🐢 Why is my internet slow after connecting to VPN? How to improve speed?
-
Check the server list, and select a node with low latency and high speed
-
If you're in mainland China, enable:
-
Global Mode + Local Bypass
-
This will let local websites skip the VPN, improving overall speed
