As of 2026, simply connecting your VPN within China does NOT guarantee its proper functionality. Numerous users face challenges such as:
- Connected status, yet foreign websites won't load;
- Google is accessible, but YouTube/ChatGPT are not;
- Browsing speeds are significantly reduced;
- Applications work, but websites fail to load;
- Mobile data is unusable while WiFi works—or the other way around.
This guide outlines the most effective testing strategies to confirm whether your VPN genuinely operates in China.
1. Step One: Verify Basic Connectivity
Test 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 recognized.
2. Step Two: Evaluate DNS Integrity
