As of 2026, simply connecting your VPN in China does NOT guarantee it is operating properly. Numerous users face issues such as:
- Connection established, yet foreign websites fail to load;
- Google functions, but YouTube/ChatGPT do not;
- Browsing speed is unusually slow;
- Apps are usable, but websites are unresponsive;
- WiFi is operational, but mobile data is not—or the other way around.
