In 2026, connecting your VPN in China does NOT necessarily mean it is fully working. Many users experience situations like:
- Connected, but foreign sites won’t load;
- Google works, but YouTube/ChatGPT fail;
- Very slow browsing speed;
- Apps work, but websites don’t;
- WiFi works, mobile data doesn’t—or vice versa.
This guide provides the most practical testing methods to verify whether your VPN is actually functional in China.
1. Step One: Test Basic Connectivity
Check if you can open:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these sites fail to load:
- Your DNS may be polluted;
- The server may be partially blocked;
- The protocol may be detected.
2. Step Two: Test DNS Accuracy
DNS pollution is one of the most common causes of failure in China.
