SIM Lock Release

You can use eSIM if your device is SIM-free. If it is not SIM-free, a SIM lock release is required.
For instructions on how to release the lock, please check the website of your current mobile carrier.
Internet Environment

Downloading the eSIM is done by connecting to a network such as Wi-Fi.
Customers traveling to Japan can download the eSIM before leaving their country to be able to use the internet immediately upon arrival in Japan.

*This product is for use exclusively within Japan. Also, as it is for data communication only, it cannot be used for calls or SMS.

About Recharging

You can easily recharge your Sophia eSIM’s data from the site below and continue using it as is!
