A check-process guide for phone compatibility, SIM lock, purchase region, OS, and provider setup requirements.
This page does not promise that a specific phone will work with a specific provider or plan. It explains what to check before choosing a Japan eSIM, physical SIM, or another option.
A phone may have different capabilities depending on model, region, carrier, and software. Check the device settings, manufacturer information, carrier information, and provider setup instructions before you choose.
A carrier-locked phone may not be able to use a travel eSIM or physical SIM in the way a traveler expects. Confirm lock status before relying on a SIM-based option.
