A Genki Mobile Travel Physical SIM card is a small chip you insert into your phone to use mobile data in Japan. Once the SIM is installed and your phone is set up correctly, it connects to a local Japanese network, allowing you to use the internet shortly after landing—without needing a separate Pocket Wi-Fi device.
Genki Mobile’s Travel SIM is a good option for travelers who prefer a simple setup or whose phones don’t support eSIM. It offers a straightforward way to get mobile data in Japan using your own smartphone.
