India Unlimited data
3-day plan

1GB a day at full speed, then 5Mbps (video stays smooth)

This is a data-only plan — no phone calls, and no sending or receiving SMS.
The date rolls over around 01:00 Japan time — activating just before that can burn most of day one

Only with eSIM.co.jp

Support you can count on
If a network problem stops you using the plan, we look into what happened and then refund you or send a replacement eSIM.

Your Japanese line stays in the phone. Your number and LINE do not change.
