My eSIM Japan worked well throughout my trip. Easy setup and reliable data made it a great eSIM for Japan travel.

It's a lifetime eSIM, so I just keep topping up wherever I travel.

Your 7 days starts at your first connection abroad, not when you pay — and it runs as a rolling window. Connect at 01:00 and it lasts until 01:00 on day 8, not to midnight.
Does your phone support an eSIM?
Dial *#06# on your keypad. If the panel that opens lists an EID, your phone is eSIM-ready. It works on iPhone and Android, takes about ten seconds, and nothing leaves your device.
- Open the Phone appThe normal dialler — the one you make calls from.
- Type *#06#No need to press call — the panel opens on its own.
- Look for EIDA 32-digit number under the IMEIs. If it is there, you are eSIM-ready.
No EID? The phone takes a physical SIM only, and a travel eSIM will not work on it. If the EID is there but your handset came from a carrier, check it is not network-locked before you buy.
Installed before you board
Your QR arrives by email the moment payment clears. Install on the sofa, land in Tokyo connected.
Choose unlimited, fixed data, or data with calls. The price you see is the price you pay.
It lands in your inbox instantly. Install the profile at home over Wi-Fi and leave it dormant.
The plan activates the moment you connect in Japan — validity starts then, not at purchase.
Your eSIM never expires
Only a plan has a validity. The eSIM stays on your phone, so whenever you need data again you add a new plan to the same eSIM.
- No new QR codeA top-up goes onto the eSIM you already installed. Nothing to scan, nothing to reinstall.
- Top up for your next tripMost eSIMs take plans for other destinations too, so one eSIM can travel with you.
- Plan expired? Add anotherWhen a plan runs out, the eSIM stays. Add a new plan and carry on with the same profile.
