As of 2026, simply connecting your VPN in China does NOT guarantee its proper functionality. Numerous users face challenges such as:
- Connected, yet unable to access foreign websites;
- Google is operational, but YouTube/ChatGPT is unavailable;
- Low browsing speeds;
- Applications are accessible, but webpages aren’t;
- WiFi is functional, but mobile data fails—or the other way around.
This guide outlines the most effective testing procedures to check if your VPN is genuinely working in China.
1. Step One: Verify Basic Connectivity
Test if you can access:

If these sites don’t load:
- Your DNS might be corrupted;
- The server could be partially restricted;
- The protocol may be recognized.
2. Step Two: Verify DNS Correctness
