Direct answer
Choose based on coverage, access to the services you need, phone compatibility and whether you require a mainland Chinese number. International roaming or a travel eSIM can be convenient; a local SIM may offer local data and a Chinese number but normally requires passport registration.
What to know
- ●Check that your phone is unlocked and supports the exact SIM or eSIM product before purchase.
- ●Ask how internet traffic is routed because access to international services can differ between products.
- ●Keep an offline copy of the activation instructions and do not rely on a newly purchased connection as your only way to reach bookings.
