- 01
Check that your phone supports the plan and it explicitly covers mainland China. Ask the provider about its routing and access to your essential apps.
- 02
Check activation, data, hotspot and SMS rules. Keep your regular number available if it receives payment verification codes.
- 03
Download offline maps and translation packs; save hotel addresses, bookings and key documents offline.
Connection is separate from payment verification
Changing SIM or data provider does not complete identity checks in Alipay, WeChat Pay or TenPayGo. Follow each payment app’s own verification prompts.

If something gets stuck

I have data but no SMS codes.
Many travel plans are data-only. Keep a number that can receive the codes you need.
