5G Unlimited Travel eSIM
The day your device connects to the network in Japan will be counted as the first day of the rental period (regardless of the date selected at checkout). You may install it prior to your departure in your home country.
Once you have arrived and connected in Japan, your eSIM will be active according to the duration you purchased, with the day you first connect counting as day 1.
For example, if you buy an unlimited 5G eSIM for your 10-day Japan trip (from January 1st to January 10th):
・If you install it before you arrive in Japan, your usage will start once you connect in Japan.
・If you install it after you arrive in Japan, your usage will start immediately once it is installed.
*e.g. Connecting with the eSIM anytime on January 1 means you can use the eSIM until 23:59 (11:59 PM) on January 10; you can use it until the very end of January 10th.
**e.g. Connecting with the eSIM at 23:59 (11:59 PM) on January 1 means you can use the eSIM until 23:59 (11:59 PM) on January 10. - Even if you only have a few minutes on your 1st day (January 1st), it is still counted as Day 1 of your eSIM usage period.
Please note that extension is not possible with our 5G eSIM, so if you wish for more days, you will need to purchase a new eSIM.
4G Unlimited Travel eSIM
The day you install the 4G Travel eSIM (add it to your device) will be counted as the first day of the rental period.
For example, if you buy an unlimited 4G eSIM for your 10-day Japan trip (from January 1st to January 10th):
・If you purchase it before you arrive in Japan, we recommend you install the eSIM on the day of your arrival in Japan, as this will be the 1st day of the 10-day eSIM.
*Our eSIM data connection is only available for use within Japan. You can install it before arriving in Japan; however, please note that the usage period will begin immediately upon installation.
This means that if you install the eSIM while outside Japan, your 10-day usage period will already have started, and you will not have the full 10-day period remaining upon your arrival in Japan.
・If you purchase it after you are in Japan, you can install it anytime depending on your needs, and that day will be the 1st day of the entire 10 days.
*e.g. Installing the eSIM anytime on January 1 means you can use the eSIM until 23:59 (11:59 PM) on January 10; you can use it until the very end of January 10th.
**e.g. Installing the eSIM at 23:59 (11:59 PM) on January 1 means you can use the eSIM until 23:59 (11:59 PM) on January 10. - Even if you only have a few minutes on your 1st day (January 1st), it is still counted as Day 1 of your eSIM usage period.
