As of 2026, simply having your VPN connected in China does not guarantee it is functioning properly. Numerous users face issues such as:
- Connection established, yet foreign websites won’t open;
- Google is accessible, but YouTube/ChatGPT are not;
- Browsing is sluggish;
- Applications operate, but web pages do not;
- WiFi functions, whereas mobile data fails—or the other way around.
This guide offers the most effective testing techniques to determine if your VPN is genuinely operational in China.
1. First Step: Verify Basic Connectivity
Confirm if you can access:

If these websites don’t load:
- Your DNS might be compromised;
- The server could be partially restricted;
- The protocol might be recognized.
2. Second Step: Assess DNS Precision
