Japan eSIM quick answers
How do I get a Japan eSIM?
Buy online and your QR code arrives by email - scan it to install. eSIM only, nothing is posted.
Should I install it before I fly?
Yes - install it at home over Wi-Fi, so the setup is already done when you land.
How much data do I need for one or two weeks?
The daily plans give 2GB at high speed every day, so a short trip needs no gigabytes counting. We also have 1-year and regional plans if your trip is longer.
Does it come with a phone number, calls or SMS?
No - the plan is data only. Keep your own SIM in the phone for calls and messages.
Can I share the connection with a hotspot?
Yes - hotspot sharing is included, so a second device can ride the same plan.
Is a Japan eSIM better than renting a pocket WiFi?
An eSIM lives in your own phone - nothing to collect, charge or return. Pocket WiFi suits larger groups.
Which networks does it use, and how fast is it?
KDDI and SoftBank on 4G and 5G. Unlimited daily plans give 2GB at high speed each day, then unlimited at 5Mbps until the 00:00 Japan time reset.
Does my phone support eSIM?
Dial *#06# - an EID beside the IMEI means it is eSIM-ready, and the phone must be carrier-unlocked.
