Questions about eSIMs in Japan

Will my eSIM work in Japan?

Yes. Your eSIM connects to local networks in Japan. Before you buy, check that your phone supports eSIM and isn’t carrier-locked.

When does my Japan plan start?

When your eSIM first connects to a network in Japan, not when you buy or install it. Install it at home on Wi-Fi.

Can I keep my own number?

Yes. The eSIM is data only, so your own SIM stays in your phone for calls and texts. WhatsApp and iMessage keep working over data.

What if I visit more countries after Japan?

Add them to your route. We compare one regional eSIM against separate local plans and show you the cheaper option.

Which networks does the Japan eSIM use?
