Проверьте перед действием
Check the current screen, the conditions that may change and the fallback before making a critical decision.
Choose by the service you need
Compare home-number roaming, a travel eSIM and a mainland SIM by data, calls, SMS, tethering, device compatibility and access to account-recovery codes.
Keep two independent paths when possible
A travel eSIM is often data-only and may not provide a +86 number. Keep the home line available for critical codes and test the selected data route after arrival. See the current SIM and eSIM guide for device and account branches.
