Local SIM basics
A local SIM can be useful for longer trips, local calls, delivery coordination, and stable China mobile data. Expect real-name registration and bring your original passport.
The main operators are China Mobile, China Unicom, and China Telecom. Airport counters, city service offices, or official retail outlets are safer choices than informal sellers.

When roaming is simpler
For a short trip, international roaming or a travel eSIM can be easier because your home number remains reachable for bank checks, wallet verification, and account recovery.
A local SIM does not automatically make blocked foreign services available. Separate the question of mobile data from the question of which apps and sites work on mainland networks.
Before switching numbers
Make sure Alipay, WeChat, banking apps, hotel bookings, and transport apps can still receive verification. Some failures come from losing access to the phone number used during setup.
Save offline documents and key addresses before changing SIMs, so a temporary data or SMS problem does not block your arrival day.
