As of 2026, simply connecting your VPN in China does not guarantee that it is functioning properly. Numerous users encounter issues such as:
- Connected, yet foreign websites fail to load;
- Google operates, but YouTube/ChatGPT do not;
- Browsing speeds are exceedingly slow;
- Applications work, but web pages do not;
- WiFi works, but mobile data does not—and vice versa.
This guide outlines the most effective testing techniques to determine if your VPN is truly operational in China.
1. Step One: Verify Basic Connectivity
Make sure you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites cannot be accessed:
- Your DNS might be compromised;
- A portion of the server may be restricted;
- The protocol could be identified.
2. Step Two: Assess DNS Integrity
