Overview of eSIM
An eSIM card – or virtual SIM card – is a SIM card that is embedded in a mobile device. An eSIM works the same way as a traditional SIM, but you don’t need any physical SIM card anymore. The eSIM is welded in your device and activated over the air. The eSIM is also sometimes called by its technical name, eUICC (Embedded Universal Circuit Card).So, with an eSIM-enabled device you can easily buy a mobile data plan when you need it, on the go. More and more smartphones, tablets and laptops are equipped with eSIM.
