About HD Telecom
HD Telecom provides SIM cards, mobile data and Wi-Fi services, mainly for international residents living in Japan. Our goal is telecom service that is easy to understand and safe to use, tailored to each customer's needs.
How we work
In the customer’s language
Website, setup guides and support in five languages. Nobody should have to guess at the meaning of a telecoms contract.
Terms stated plainly
If a plan has no voice calls, we say so. Speed limits, device compatibility and renewal fees are stated up front, not buried in footnotes.
From lived experience
We were once new arrivals ourselves — no Japanese, lost in paperwork. The service is built backwards from those difficulties.
