Where does Japan eSIM work?

Open “Plan details” to see where your chosen plan works. Coverage can vary between plans, so check every stop on your route. Your connection also depends on the local network and your phone.

A few things before you go

1. Check your phone. It must support eSIM and be carrier-unlocked. See the iPhone or Android setup guide.
2. Check when validity begins. The plan details show whether the clock starts after purchase, at installation or on the first network connection. Do not assume every offer starts on arrival.
3. Choose enough data and days. Daily data and total data work differently. See how to estimate travel data.
4. Set up the included VPN separately. Stellar VPN is included for the plan’s validity. Follow your order’s access instructions; buying an eSIM does not switch the VPN on automatically.
5. Buy in the app. Confirm current coverage and pricing, then follow the installation instructions and monitor your usage in Stellar eSIM.
