As of 2026, simply connecting your VPN in China doesn’t guarantee full functionality. Numerous users face challenges such as:
- Connected, yet foreign websites fail to load;
- Google is accessible, but YouTube/ChatGPT are not;
- Browsing speeds are significantly slow;
- Applications function well, but websites do not;
- WiFi operates, but mobile data fails—or the other way around.
This guide outlines effective testing methods to confirm if your VPN is operational in China.
1. Step One: Verify Basic Connectivity
Determine if you can access:

In case these websites do not load:
- Your DNS might be compromised;
- The server could be partially restricted;
- The protocol may be detected.
