What's eSIM?
eSIM is a smartphone with embedded SIM otherwise known as Digital SIM.
If you have an eSIM compatible smartphone, you can sign up the mobile service without newly inserting the physical SIM or replacing the SIM with the existing one. If the device has DSDS: dual SIM dual stand by function, you can even use two different carrier mobile services on one device.
Advantages of eSIM
You can have 2 numbers on 1 device.
Therefore, you can keep your US number while having a Japanese number as well!
You can customize your physical and eSIM! Calls and texts can be set to your US number while data can be set to the Y!mobile eSIM.
