プリペイドSIM屋さん

Prepaid SIM Shop is a service that allows you to complete everything from purchasing a prepaid SIM card with a phone number usable in Japan to managing it after activation, all through a single app.

Simply choose and purchase the plan you need, and with eSIMs, you can proceed directly to activation. After purchase, you can check your data allowance and expiration date in real time through the app, so you can always keep track of your remaining data and expiration date.

The service also supports extending the usage period; you can manually extend it when needed, or set up automatic extensions via subscription. This reduces worries about expiration and allows for continued, worry-free use.

If you run out of data, you can top up your data allowance through the app. The recharge is reflected immediately, so you can smoothly add data even when you suddenly need more.

Furthermore, you can activate a line with a phone number that can receive SMS messages on the same day, without any troublesome identity verification procedures or credit card registration.

You can also manage account information, purchase history, and various settings within the app.
