How long can I use the Japan eSIM?

Plans are available for 1, 3, 5, 7, 10, 15, 20 or 30 days.

How much data can I get for Japan?

Options include 1GB, 3GB, 5GB, 10GB, 20GB and 50GB, as well as unlimited data.

Japan: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in Japan means finding a shop once you have landed, usually with ID in hand, and it leaves you on a single carrier. An eSimHero eSIM installs before you travel, works the moment you arrive, connects across the networks we carry there, and leaves your usual number active on the same phone.
