Heads up: DTI SIM's official application and support are in Japanese only, as far as we could confirm. You (or someone helping you) will likely need to read Japanese to sign up.

Frequently asked questions

Does DTI SIM accept applicants with a residence card and no Japanese credit history?

Yes — DTI SIM accepts residence-card holders (per official pages). A residence card is accepted as ID. That's a separate question from credit screening for the line contract itself: screening terms exist; see official page.

Can I pay DTI SIM without a Japanese credit card?

Not stated clearly either way on the official pages we checked.

Is eSIM available from DTI SIM?

No — the DTI SIM plans we track are physical-SIM only.
