Before you enquire

What you need to provide

  • An active Japanese SIM with a number

    Including voice and the SMS services you need.

  • A suitable location in Japan

    With permission to install the equipment and coverage from your operator.

  • Reliable internet and power

    To keep the adapter connected.

  • A compatible plan and device

    We check the model, applicable requirements and the operator's permitted use.

  • Someone available locally

    To connect the equipment or help with physical checks.

  • Your service requirements

    Tell us which calls and SMS you need to receive.

A data-only travel SIM is insufficient for this setup. Service depends on the technical review and operator conditions. A Japanese telephone number does not establish a Japanese office or registered business address.

First, we review your setup

Tell us what you need to connect.

We review your operator, SIM, location, equipment and required services before proposing an installation.

Request a compatibility review

Equipment, configuration and service are quoted for your setup. Your mobile plan, local internet and electricity remain separate.

Questions about Japan SIM Hosting

Can I buy a Japan National +81 50 number here?

No. This service connects your own Japanese mobile SIM; it does not sell or replace a National +81 50 number.

What if I do not have a Japanese SIM yet?

You arrange your own SIM through an authorised operator and meet its registration requirements. Check the intended plan and equipment with us before committing.

Where does the adapter stay?

At the location you provide in Japan. You maintain the local internet and power; we configure the agreed service.

Will every call, SMS or bank verification code work?

Support depends on the operator, plan, equipment and sender. Bank codes, OTP delivery and third-party platform acceptance are not guaranteed.
