What is eSIM?
eSIM is an “Embedded SIM” that it’s designed to be built in a wide range of devices including consumer smartphones. eSIM allows you to activate multiple operator data plans on a device and switch between them without using a physical SIM card. As long as your phone is compatible with eSIM, you can enjoy the convenience it brings to our lives (eSIM Compatible Devices Checklist).
Precautions of using eSIM
The first thing is to confirm whether your phone is unlocked. If your mobile phone is purchased from a major carrier, they can unlock eSIM for your phone under certain conditions. And it really depends on whether your phone is paid in full or in installment.
