No surprise fees or roaming chargesAn eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.
Dig into tasty food, check out iconic landmarks like the Imperial Palace, Tokyo Skytree, or the Senso-ji Temple, and get a real feel for the traditions that make Tokyo a must-see place to visit.

You won’t pay a penny in roaming charges!
Install your Tokyo eSIM while you have a strong internet connection (either at home, or while already travelling), and then activate your prepaid Tokyo data package when you’re ready to use it.
To avoid roaming charges on your primary SIM, please make sure you’ve turned off Data Roaming on your primary SIM to prevent your home carrier from adding roaming charges to your next bill.
Most newer phones, tablets, and computers are already eSIM-compatible, so use our eSIM device checker to make sure you have a device that can accept an eSIM.
