Japan eSIM on NTT docomo: questions

Does a NUM Japan eSIM use NTT docomo?

7 of the Japan plans in the shop on 4 Nov 2026 listed NTT docomo; others use KDDI/au or Rakuten Mobile. Each plan lists its networks before you pay.

How much is a Japan eSIM on NTT docomo?

On 4 Nov 2026, from $0.79 (500 MB, valid 7 days). The price on the pay button is the price you pay.

Can I choose NTT docomo over another network?

Pick a plan that lists NTT docomo. Your phone joins NTT docomo when it is in range; with data roaming on, it can also use the plan’s other listed networks.

Will I get a NTT docomo phone number?

No. It’s a data-only eSIM that runs on the network; your home number stays on your phone for calls and codes.

Will it work on my phone?

Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.

When do I install it?

At home, on wifi, before you fly. Then switch it on when you land. Tell us your landing day and we text you the switch-on steps that morning.
