5G Unlimited eSIM

You may install the eSIM before you arrive in Japan, however you will not be able to activate it until after you are in Japan. We generally recommend installing after or just before coming to Japan to prevent any issues.

If you install the eSIM, then the eSIM will activate immediately when you are in Japan, regardless of the date entered for the order, so please only install it on the day you wish to start using it.

4G Unlimited eSIM

Please install the eSIM profile after you arrive in Japan.
We sometimes see occasional errors when the eSIM is installed outside of Japan.
Also, please note that the day you install our eSIM will be the day that rental period starts.

For example, in the case of a 10-day eSIM:
・If you purchase the eSIM before you arrive in Japan, then we will recommend you to install the eSIM on the day of arrival, as this will be the 1st day of the 10 days period.
・If you purchase the eSIM when you are in Japan, you can install it anytime depending on your needs, and that day will be the 1st day of the 10 days period.
※ e.g. Installing the eSIM at 00:00 on January 1 means you can use the eSIM until 23:59 on January 10.
※ e.g. Installing the eSIM at 23:59 on January 1 means you can use the eSIM until 23:59 on January 10.
