What is a Japan eSIM?

A Japan eSIM is a digital SIM you install on your phone before you travel — no plastic card, no swapping. Buy online, scan a QR code, and land in Japan already connected to a local network. You keep your home number for calls and messaging apps while your travel data runs on the eSIM.

Frequently asked questions

When does my plan start?+

Validity begins the moment your eSIM connects to a network in your destination — not when you buy it — so you can install it in advance.

Will I keep my phone number?+

Yes. The eSIM carries your travel data while your regular SIM keeps your number for calls and texts.

Is my device compatible?+

Most phones from the last few years support eSIM. Check our device compatibility page if you're unsure.

What if I run out of data?+

On top-up-ready plans you can add more data instantly from your dashboard — no need to reinstall.
