What is an eSIM?

Modified on Mon, 20 Nov 2023 at 04:47 AM

eSIM, standing for Embedded Subscriber Identity Module, is a digital Sim card embedded in a mobile device and can connect you to any operator offering eSIM services. You cannot remove it and insert it to another device. 

It is physically connected (soldered) to the motherboard. You could activate it by setting up the “eSIM profile”, a new operator. 

The information on an eSIM is rewritable, so you can switch your network without having to remove your SIM and insert another.

The eSIM function is available on newer models of iPhone, Samsung, and even some laptops like Dell or HP.  You can see the list of eSIM compatible devices here.
