An eSIM is a digital SIM that works like a physical SIM card. eSIM stands for “embedded SIM.” Unlike the traditional plastic SIM card, an eSIM does not need to be inserted into your device. Instead, it can be downloaded directly onto your phone and provides the same cellular connection.

Similar to a physical SIM card, the eSIM stores the data that enables your device to connect to cellular service and use your plan on the network.
