Japan eSIM questions

Which network will my eSIM use in Japan?

Your eSIM connects automatically to Discover and its roaming partners in Japan, selecting the strongest available signal. There is no manual network setup.

Will the Japan eSIM work as soon as I land?

Yes. Install the profile before you fly, switch data roaming on for the eSIM line after landing in Japan, and it registers on the local network within a minute or two.

Do I need an ID or local address to buy a Japan eSIM?

No. Unlike buying a physical local SIM in Japan, there is no registration, no passport check and no queue at an airport kiosk.

How much data do I need for a trip to Japan?

For maps, messaging and light browsing, 1GB per week is usually enough. If you stream, video call or work remotely, plan for 1GB per day. You can always top up mid-trip.
