01
Before buying any plan, identify the exact phone model and the country where it was sold.
Check its eSIM capability and carrier lock. Use the model shown in device settings rather than relying only on a familiar product name.
02
Ask your existing carrier for its mainland-China roaming offer.
Compare that option with a travel eSIM’s data allowance, validity, hotspot permission and supported countries. Choose the route that supports the services you need at a cost you understand.
03
If choosing another carrier’s eSIM, confirm device compatibility before payment and install it according to the provider’s instructions.
Keep a working internet connection for setup and save the activation and support information outside the provider app.
