Which apps are blocked, which VPNs still work reliably, and the eSIM setup that takes friction out of the first afternoon.
Before arrival
Install VPNs, maps, translators, and backup messaging apps before landing. Some app stores and websites are harder to reach once you are already in China.
eSIM or local SIM
An international eSIM is the fastest start. A local number unlocks deeper domestic services, but it takes more setup.
Daily reliability
Keep at least two connection options: hotel Wi-Fi plus mobile data, or a primary VPN plus a backup app.
