What is eSIM?
Most people know what a SIM card is, they are a small card that sits in the phone and is used to help the phone connect to a specific wireless carrier and use the plan.
Now, eSIM is here and more and more smartphones, tablets and laptops are equipped with eSIM cards. It is a SIM card embedded in your mobile device that connects you to any operator that offers eSIM services. You don’t need a physical SIM card to use it, it exists in your device and you just need to activate it to use it, or even simply switch to a different operator just in the phone settings.
What’s the difference between an eSim vs a physical SIM card?
An eSIM is a digital version of a traditional physical SIM card – a device that is identified and provided with services in the network. It is usually installed in a smartphone by technical means. This greatly improves the experience for people, for example when you change your phone or wireless operator, which you can do with a simple action from anywhere.
