How it works
Three steps, no app and no account. Your eSIM arrives by email as a QR code.
Pick your destination and compare data, validity and price on one screen. Pay by card or with PayPal.
Scan the QR code we email you within seconds of payment. Install it on Wi-Fi before you fly, then turn on data roaming for the eSIM when you land.

No contracts, no store visits, no waiting. Just data that works where you are going.
Questions
An eSIM is a digital SIM built into your phone. It downloads a mobile data plan by QR code, so you can use local networks in Japan without buying or inserting a physical SIM card.
Install it the day before you travel or just before departure, while you still have Wi-Fi at home. The plan's validity does not start until your phone connects to a supported network in Japan.
Your plan starts when your phone first connects at your destination. Running low? Top up the same eSIM in a minute.
Regional and worldwide plans cover whole continents on a single profile, so a multi-country trip does not mean multiple purchases.
Your QR code is emailed the moment payment clears — not hours later, and not once you have already landed.
Install at home on Wi-Fi and the plan waits. Validity begins at your destination, not at the checkout.
