China eSIM guide: networks, access and setup
In mainland China, how your data is routed matters more than speed: a local Chinese SIM goes through the domestic network, where Google, KakaoTalk and Instagram are blocked.

Must-knows
- Roaming-type travel eSIMs route traffic back outside the mainland (often via Hong Kong), so Google, KakaoTalk, Instagram and YouTube usually work. A local Chinese SIM does not.
- iPhones and Galaxy phones sold in mainland China mostly have no eSIM. Korean-bought phones are fine if they support eSIM.
- Alipay, WeChat Pay, Didi and map apps work on any connection; download them and set them up before you go.
Buying a local SIM
Local SIMs are sold at airport counters and operator stores. Real-name registration with your passport is mandatory, and includes live face verification against your passport photo.
Weak-signal areas
Coverage is strong in cities and along high-speed rail. Remote western regions (Tibet, Xinjiang) and mountain scenic areas can be weaker.
