Japan eSIM questions
Which networks does Roamy use in Japan?
Roamy plans for Japan run on NTT docomo, Rakuten Mobile, KDDI/au and SoftBank, with speeds up to 5G where the network offers it.
How much data do I need for a week in Japan?
About 1 GB a day covers maps, photos and the odd video call. For a week we recommend 10 GB for 30 days at $16.00.
When does my Japan plan start?
The validity period starts when the eSIM connects to a supported network. Install it before you fly; it waits until you land.
Is there a plan for Japan and other countries?
Yes. Asia and Global plans include Japan along with other countries. Each plan lists exactly which countries it covers.
Can I add more data later?
Yes, on most plans. Add data in the Roamy app and it goes onto the eSIM you already have, with nothing new to install.
