As of 2026, merely connecting your VPN in China does not guarantee it is functioning properly. Numerous users report experiencing issues such as:
- Connected, yet international websites won't load;
- Google is accessible, but YouTube and ChatGPT are not;
- Browsing speed is extremely slow;
- Applications function, but websites do not;
- WiFi is operational, but mobile data is not—or the other way around.
This guide offers the most effective testing techniques to determine if your VPN is genuinely operational in China.
1. Initial Step: Assess Basic Connectivity
Verify if you can access:
- https://www.google.com
- https://www.youtube.com
- https://chat.openai.com
If these websites won't load:
- Your DNS might be compromised;
- A partial blockage could be affecting the server;
- The protocol may have been flagged.
2. Second Step: Assess DNS Accuracy

- Employ SmartDNS mode.
3. Third Step: Verify Your IP Location
