As of 2026, setting up your VPN in China doesn't guarantee complete functionality. Users often encounter issues such as:
- Successfully connected, yet unable to access foreign websites;
- Google functions, but services like YouTube/ChatGPT do not;
- Significantly reduced browsing speed;
- Applications operate while websites do not;
- WiFi connects, while mobile data fails—or the other way around.
This guide outlines the most effective methods to test if your VPN is genuinely operational in China.
1. Initial Step: Verify Basic Connectivity
Determine if you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites do not load:
- Your DNS might be compromised;
- The server could be partially obstructed;
- The protocol may be detectable.
2. Second Step: Assess DNS Accuracy
