As of 2026, being connected to your VPN in China does not guarantee that it is functioning properly. Users frequently encounter issues such as:
- Connected, yet foreign websites fail to load;
- Google is accessible, but YouTube/ChatGPT are not;
- Browsing speed is very sluggish;
- Apps function, but websites do not;
- WiFi works, whereas mobile data does not—or the other way around.
This guide outlines effective testing methods to confirm whether your VPN is truly operational in China.
1. First Step: Verify Basic Connectivity
Determine if you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites do not load:
- Your DNS might be compromised;
- The server may be partially restricted;
- The protocol could be recognized.
2. Second Step: Assess DNS Integrity
