More about us

Questions, answered straight

When do my days start counting?

Not at purchase. Each plan states its rule at checkout: at install, or at first connection in Japan.

Can I hotspot?

Most plans allow it; each plan's own rule is printed at checkout. Hotspot uses the same data.

What if my eSIM does not work?

A faulty eSIM is replaced one for one, and a human answers on chat and email. Most no-signal cases are fixed in two minutes with the rescue card.

Can I get a refund?

Unused plans can be refunded under their package terms. Email your order number to the address in the footer.
