eSIM for Japan
Mobile data from the moment you land, without swapping SIM cards or hunting for wifi. You buy it online before the trip and activate it when you arrive.
Our pick for Japan: the Airalo eSIM.

Buy it before you leave
Choose the days and data you need and install it at home following the instructions, usually with a QR code.
Turn it on when you land
When you arrive in Japan, switch on the eSIM's data and you're online. Your usual SIM can stay in your phone.
