How to connect in Japan

  1. Choose a data plan and pay — no shop, no passport, no local contract.
  2. Install the eSIM from the email or the app: one tap, or scan the QR code.
  3. Land in Japan, turn on data roaming for the Letisim profile, and you are online.

Check before you buy

  • Confirm that your exact phone supports eSIM and is carrier-unlocked.
  • Plan availability, price, data and validity can change; the live catalog is authoritative.
  • Network and local coverage are not guaranteed unless they are shown and confirmed for the selected plan.

Questions about eSIM in Japan

Can I buy a Japan eSIM online before I fly?

Yes. You buy and install it before departure, so data works the moment you land. Nothing needs to be collected in Japan.

Does a travel eSIM in Japan give me a phone number?

A data plan gives you mobile internet, not a local number. Your own number stays active in the phone for calls and SMS codes.

Is there unlimited data for Japan?

Unlimited plans appear in the list above when they are published for Japan. Check the plan card for its fair-use terms before buying.

Will my phone work with an eSIM in Japan?

Your phone must support eSIM and be carrier-unlocked. Model support alone is not enough — the exact regional version matters too.
