A question about a plan, an installation or an order? Send an email. A person reads it, and there is no phone menu in front of it.

Write in any of the languages this site is published in; the answer comes back in the language you used.
Response time
We reply within one business day and usually much sooner. We work on European hours, which sit behind Japan's clock — a message sent in the Japanese evening is normally answered before you wake up.
Faster in the app
Once the eSIM is installed, write from inside the app: your plan details ride along with the message, which saves a round of questions.
