As of 2026, having your VPN set up in China does NOT guarantee it will function properly. Numerous users encounter problems such as:
- Connected, yet foreign websites refuse to load;
- Google operates, but YouTube/ChatGPT do not;
- Browsing is extremely sluggish;
- Apps function, but websites are unresponsive;
- WiFi connects, but mobile data fails—or the other way around.
This guide outlines the most effective testing techniques to confirm if your VPN is genuinely operational in China.
1. First Step: Verify Basic Connectivity
Try accessing:
- 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 could be partially blocked;
- The protocol may be identified.
2. Second Step: Assess DNS Integrity
