CN China Entry Guide Arrival Toolkit eSIM Airport Arrival China phone number guide A local phone number can help with some apps and services, but many short-term tourists can use eSIM or roaming plus payment apps.
Decide whether you need a China number.
Short trips may only need data; longer stays may need SMS verification and local services.
If buying a local SIM, prepare passport registration and check airport or carrier store availability.
Ask whether the plan includes data, calls, SMS, validity period, cancellation rules, and English support.
Keep your original phone number active if your bank or payment apps need security messages.
Test SMS, data, maps, and payment apps before leaving the airport area.
