eSIM works the same way as a traditional SIM card, but you don’t need a physical SIM card. It is pre-installed in the device and you can activate it by installing the “eSIM profile” of a new operator.
The profile is simply installed by scanning an eSIM QR-code which then downloads the eSIM profile to your phone.
Done!

It is an evolution of the physical SIM card.
More and more smartphones, tablets and laptops are equipped with an eSIM card.
