1. What is an eSIM?

An eSIM (electronic SIM) is a technology that allows you to use a mobile carrier’s service without inserting a physical SIM card, using a chip embedded in smartphones and tablets. eSIMs are very convenient for travelers as they can be contracted and activated smoothly online.Advantages of eSIMs
- Easy setup: You can contract online and start using it just by scanning a QR code.

4. Points to Note When Using eSIMs in Japan

After purchasing an eSIM, install it by scanning the QR code and activate it from the settings screen. It’s recommended to complete the setup before your trip so you can use the internet immediately upon arrival.

Choose an appropriate data plan based on your travel duration and data usage. For short trips, 1GB or 2GB plans are recommended, while 5GB or unlimited plans are suitable for longer stays.
