As of 2026, simply connecting your VPN in China does not guarantee that it is operating effectively. Numerous users encounter scenarios such as:
- Connected, yet cannot access foreign websites;
- Google operates, but YouTube/ChatGPT does not;
- Browsing is exceedingly slow;
- Apps function, but websites are unresponsive;
- WiFi is operational, but mobile data fails—or vice versa.
This guide outlines the most effective methods for testing and confirming that your VPN is indeed working in China.
1. Step One: Verify Basic Connectivity
Determine if you can access:

- https://chat.openai.com
If these websites do not load:
- Your DNS could be compromised;
- The server might be blocked to some extent;
- The protocol could be recognized.
