Excellent Coverage, Even in Rural Areas
Japan boasts some of the best mobile networks in the world. Our eSIMs rely on national networks, including the Shinkansen and most rural tourist areas.
Subway stations and commercial basements are covered, which is not always the case across Asia.
eSIM or Wi-Fi Pocket?
A Wi-Fi pocket remains a good option for multiple users since it can be shared. However, it needs to be removed, charged daily, and returned before departure.
For one or two travelers, eSIM is simpler: nothing to retrieve, nothing to return, and each phone stays independent if you separate during the day.
Settings to Adjust Before Your Flight
Install the eSIM over Wi-Fi before you leave, download an offline map of Tokyo, and ensure that data roaming is enabled only on the eSIM line.
Keep your home line active for bank validation SMS: overseas card payments often trigger these.
