How it works

From checkout to connected in one minute.

No plastic SIM, no store queue. Here's the whole journey — and exactly how to install the eSIM on any phone.

How it works

Three steps, about a minute.

No shipping, no shop, no passport scan at a kiosk. The whole purchase happens on your phone, including the part where the data starts working.

Pads light as the profile installs — you see it happen on the success screen.

  1. 01

    Choose your destination

    Search a country or region and pick the plan that matches the trip — data, days, done.

  2. 02

    Scan the QR

    One page of checkout. The QR appears immediately and lands in your inbox — nothing ships, nothing waits.

  3. 03

    You're connected

    Follow the steps for your handset and step off the plane already online. It takes about a minute.

Install guide

Scan and connect.

Follow the steps for your device. You can install before you fly — data only starts once you connect at your destination.

  1. 01Open Settings → Mobile Service → Add eSIM.
  2. 02Tap “Use QR Code” and scan the code from your confirmation.
  3. 03Label the plan (e.g. “Kirosim Japan”) and continue.
  4. 04Turn on Data Roaming for the Kirosim line — this uses the local network, not your home carrier.
  5. 05Set Kirosim as your Mobile Data line and you're online.

An eSIM is a digital SIM built into your phone. Instead of a plastic card, you install a mobile plan by scanning a QR code — no swapping, no store visit.
