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.

eSIM vs roaming

Same trip. No bill shock.

A travel eSIM replaces the airport SIM queue and the overage text with a QR code you scan before you leave home.

Typical install

  • Instant QR delivery

    The code appears the moment payment clears, and lands in your inbox as well.

  • Keep your own number

    The eSIM runs alongside your usual SIM, so calls and messages carry on as normal.

  • Local 4G and 5G

    Every plan rides a national operator in the country you're visiting — no throttled fallback.

  • No contract, no surprises

    You pay once for a set amount of data and days. Nothing renews on its own.

FAQ

Questions, answered.

Help centre

Everything worth knowing before you fly. If something is missing, the support desk answers in minutes, in any time zone.

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.
