Japan eSIM – 1GB, 7 Days
Plan your data before you travel
Your data budget
143MBPlanning average per daySharing 1GB across 7 days gives a planning average of about 143MB per day. This is not a daily limit: you can use the total allowance unevenly before it expires.
- Internet breakout
- Japan
Compare this budget with your recent phone usage. Video, work calls, tethering and cloud backups can use substantially more than maps or messaging. Download large files and offline maps over Wi-Fi when practical.

Questions about this plan
How much data does the 1GB Japan eSIM include?
It includes 1GB of data to use over 7 days in Japan. Top-ups are available if you need more.
When does the 7-day validity start?
Validity starts when the eSIM first connects to a supported network, so you can install it before you travel. If unused, activate it within 180 days of purchase.
Which mobile network does it use in Japan?
It connects through NTT docomo (5G). Coverage and speed depend on local availability.
Does it include a phone number, calls or texts?

Will it work on my phone?

Can I get a refund?
You can request a full refund within 14 days of purchase if the eSIM has not been installed or activated.
