How an eSIM QR code works, and how to use yours safely

The QR code tells your phone how to download the eSIM profile for the order. It isn't the plan itself and it isn't a public ticket to share, so keep it with the private setup email until you're ready to install after landing.

What happens when you scan it

The code carries the activation details the phone needs to reach the provisioning service and request the profile. The phone then downloads it over an internet connection, after which the data-line and order-specific settings still need to be completed.

Scanning a code is therefore part of setup, rather than a harmless way to preview the plan. It also doesn’t prove that the active service period has started: the selected offer’s billing-start rule and start-by deadline decide that.

If the QR is on the phone you're installing on

On iPhone with iOS 17.4 or later, touching and holding a supported QR in a default email app or browser can offer Add eSIM. If that method isn’t offered, display the code on another trusted screen or use the manual details supplied in the email. Android routes vary, so use our device guide for the handset you’re using.

Buy and save the email before departure, then wait until after landing on Wi-Fi that can load a normal webpage. Airport Wi-Fi is one option; if its sign-in or connection fails, use hotel Wi-Fi or another steady trusted connection instead.

If the phone says the code is used or invalid

Keep any installed profile in place and tell the Travel Desk the order number, phone model, installation method and exact error as text. A code may be limited to one installation, so repeated attempts or trying another phone can make the order harder to recover.

Don’t post the QR, quick-install link or activation string in a review or public message. If support needs an image, we’ll ask for a cropped, redacted one; there’s no need to send the whole setup email with the first enquiry.
