As of 2026, simply connecting your VPN in China does not guarantee it is fully operational. Numerous users encounter issues such as:
- Connection established, yet foreign websites are inaccessible;
- Google functions, but YouTube/ChatGPT do not;
- Browsing speed is exceedingly slow;
- Applications operate, but websites are unresponsive;
- WiFi is available, but mobile data fails—or the opposite.

Should these websites not load:
