As of 2026, having your VPN connected in China does NOT guarantee it’s working properly. A variety of users encounter issues such as:
- Connection established, but international websites won’t load;
- Google is accessible, but YouTube/ChatGPT are not;
- Browsing is exceedingly slow;
- Applications function, yet websites do not;
- WiFi is operational, while mobile data is not—or the other way around.
This guide aims to provide effective testing techniques to determine whether your VPN is truly operational in China.

If these websites do not load:
- DNS might be compromised;
- The server could be partially restricted;
