Does Notion Work in China?
Accessible, but subject to throttling or auth traps.
Bypasses the Great Firewall via overseas telecom gateways.
On Wi-Fi: Apps sync fine, but Google OAuth login dies. Fully works on foreign eSIM.
The Real Deal & Hidden Nuances
Both apps aren't directly blocked on Wi-Fi if you are already logged in. The trap triggers on the Web or new devices when you click "Sign in with Google"—the accounts.google.com OAuth popup will 100% hang and fail on hotel Wi-Fi. On a foreign eSIM, Google login works normally.
Recommended Action & Workaround
Set an email/password login or magic-link login BEFORE flying to China, and stay logged into your native apps.
