If you've bought a smartphone recently, you've probably noticed that a plastic SIM card is no longer required to use the mobile network. Instead, users simply activate their device using a QR code. The technology behind this is called eSIM, and it's already being used as a successor to the classic SIM card.

Whereas in the past, users simply swapped out their SIM cards when switching carriers, eSIM requires a different approach. Users download a digital profile, typically by scanning a QR code. Activation takes just a few minutes.

What exactly is an eSIM?

An eSIM is a small chip that manufacturers permanently embed in a smartphone. The letter "e" comes from the word embedded, which means "integrated." Unlike a plastic SIM card, this chip cannot be physically removed or replaced. All important data, such as the phone number and contract information, is stored digitally on that chip, writes Fenix ​​magazine.
