As of 2026, simply establishing a connection for your VPN within China does NOT guarantee its complete functionality. Numerous users encounter problems such as:
- Connected, yet unable to access foreign sites;
- Google functions, but YouTube/ChatGPT do not;
- Browsing speed is extremely sluggish;
- Applications work, while websites do not;
- WiFi may function, but mobile data fails—or the other way around.
This guide outlines the most effective testing procedures to check if your VPN is genuinely operational within China.
1. Initial Step: Verify Basic Connectivity
Confirm if you can access:

If these websites do not load:
