Your eSIM can only be used in one device. To make sure your eSIM can be used in your chosen device, we use your device’s EID to link it to your eSIM.
That means it’s important that when you activate, you enter the EID of the specific device that you want to install your eSIM onto.
Find out how to find your device’s EID here.
If your eSIM is deleted, it’s not recoverable, but you do have some options in order to keep your Japanese phone number – find out more here.
