How much data do I need?
Put in your trip and what you actually do on your phone. The numbers each control counts with are next to it, so you can check them.
Drag each bar to the hours a day you would spend, and the number moves as you go. The MB per hour each one counts with is right there.

Frequent questions
FAQWhat if I run out?
You top up from My Ozu without changing eSIM, and the new data is there in seconds. Nothing to reinstall.
Does hotel Wi-Fi count?
No. What you do on Wi-Fi does not touch the eSIM, so a trip with Wi-Fi at the hotel every night needs a good deal less than this says.
Do leftover gigabytes carry over?
They stay usable until the plan expires, and the days are shown next to each plan. After that they are gone.
