Frequently asked questions
How much data do I need for Japan?
Maps and messaging use far less than streaming or hotspotting. Pick the size from how you’ll use your phone, then match the days to your trip.
Where do the Ubigi prices come from?
From Ubigi’s own Japan page, read on 2026-09-29. Each row links to the exact page.
Do prices stay the same?
Not always. Operators change plans and prices, so each row shows the date we last checked it. Our own prices update live.
