Japan eSIM Store

The companion app for eSIMs bought at the Japan eSIM Store.

■ See what is left at a glance
Your remaining data and expiry date are on the home screen. If you hold several lines, they sit side by side so you can keep an eye on all of them.

■ Buy a new line without leaving the app
Pick the days and the data, and pay. The new eSIM is added to the app automatically, and the QR code is emailed to you as well.

■ Top up in two taps
Running low? Add data straight from the app. It lands in your balance right after payment.

■ Know before you run out
We let you know when your data is running low, and when the expiry date is coming up, so you are not cut off without warning.

■ No account needed
Register a line with the QR code from your purchase email, or by typing its activation code. There is no email address or password to set up.
