As of 2026, simply having your VPN connected in China does not guarantee it is functioning properly. Numerous users face issues such as:
- Connection established, yet foreign websites are inaccessible;
- Google operates, but YouTube/ChatGPT do not;
- Significantly reduced browsing speed;
- Apps are operational, but websites are not;
- WiFi is functional, though mobile data fails—or the other way around.
