As of 2026, having your VPN set up in China does NOT guarantee it operates properly. Numerous users encounter problems such as:
- Successful connection, yet foreign websites won’t load;
- Access to Google, but issues with YouTube/ChatGPT;
- Browsing is very sluggish;
- Applications function, but sites do not;
- WiFi is operational, but mobile data fails—or the other way around.
This guide outlines practical testing techniques to confirm whether your VPN is genuinely working in China.
1. Step One: Verify Basic Connectivity
Test if you can access:

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