Why this check matters
Check the complete path, not one setup step.
Mobile data alone does not guarantee access to bank messages or account recovery. Check how your travel SIM and original line will work together.
Travel SIM or eSIM
Separate mobile-data coverage from voice and incoming SMS capability.
Dual-SIM settings
Test which line handles data and which can receive verification messages without being disabled.
Account recovery
Keep bank-app approval and another payment route if an SMS code never arrives.

Before you start the check.
Will a China travel eSIM receive SMS?
Many travel eSIMs are data-only. Check the provider plan rather than assuming it includes a phone number or incoming messages.
Can I keep my original SIM active in China?
Often yes if roaming and the device configuration support it. Confirm charges, incoming message access and dual-SIM behavior with your carrier.
Why does my phone setup affect Alipay or WeChat Pay?
Banks or apps may challenge a transaction or login and require the registered number or another approval method.
