What is an eSIM and how does it work when you travel
An eSIM is a SIM card you never insert. You download it with a QR code, and a couple of minutes later your phone has a second line for mobile data.

How it differs from a regular SIM
Your phone has a built-in chip that stores the carrier profile. No plastic, no SIM tray, nothing to lose.
A phone can store several eSIMs, and usually two lines work at the same time: your own SIM and a travel eSIM, for example.
Why it helps on a trip
- Data works as soon as you land, with no carrier kiosk at the airport.
- You know the price up front and pay once per package, with no monthly fee.
- Your own number stays in the phone, so calls and texts, including bank codes, keep arriving if your carrier allows roaming.
How to buy and install it
- Pick a country or region and a plan by data and validity.
- Pay. The QR code shows up on screen and in your inbox.
- Install the eSIM at home on Wi-Fi: installing needs an internet connection.
- When you land, set the eSIM for mobile data and turn on data roaming for it.
Does your phone support eSIM
Dial *#06#. If you see an EID, your phone works with eSIM. It also has to be carrier-unlocked. More on the phones with eSIM page.
Good to know
- A travel eSIM is usually data only, with no phone number. Messaging apps cover calls.
- An eSIM profile installs once. If you delete it from the phone, it can't be restored and you'd need a new eSIM.
- Until you install it, you can cancel the eSIM in your account and get your money back.
