As of 2026, having your VPN connected in China does NOT guarantee that it functions correctly. Numerous users face issues such as:
- Connected, yet unable to access foreign websites;
- Google loads, but YouTube/ChatGPT does not;
- Browsing speeds are very sluggish;
- Apps operate, but web pages do not;
- Wi-Fi connects while mobile data fails— or the other way around.
This guide outlines effective methods for testing to ensure that your VPN is truly operational in China.
1. Step One: Verify Basic Connectivity
See if you can access:

If these websites do not load:
