🇯🇵 eSIM for Japan
Japan is one of the hardest places to arrive without data. Ticket machines, station names and restaurant menus lean heavily on apps, pocket-wifi rental counters mean a queue and a deposit, and free public wi-fi is patchy once you leave the big stations.

Practical notes for Japan
- Coverage is strong nationwide, including on most Shinkansen routes and in rural areas.
- Install before you fly — Japanese airport wi-fi works, but you will want data the moment you reach the platform, not after.
- Daily plans suit two-week trips with heavy map and translation use; fixed bundles are cheaper for short city breaks.
How to get connected
- Download Num and pick Japan.
- Choose a plan and pay with Apple Pay.
- Scan the QR code the app gives you — Settings → Cellular → Add eSIM.
- Turn on data roaming for the Num line when you land.
Questions about Japan
How much does an eSIM for Japan cost?
Plans start at $1.14. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a Japan eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
