As of 2026, having your VPN operational in China does NOT guarantee that it’s functioning properly. Numerous users encounter issues such as:
- Connection established, yet international websites won’t open;
- Google is accessible, but YouTube/ChatGPT is not;
- Browsing speed is significantly reduced;
- Applications function, but websites do not;
- Mobile data functions while WiFi does not—or the other way around.
This guide outlines the most effective testing techniques to determine if your VPN is genuinely working within China.
1. Step One: Assess Basic Connectivity
Verify 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 could be partially restricted;
- The protocol might be detected.
2. Step Two: Verify DNS Integrity
