What are embedded SIMs (eSIMs)?

The traditional SIM card “SIM” stands for Subscriber Identity Module. It is an integrated circuit are containing data to identify and authenticate subscribers of mobile phone plans. Traditionally, SIMs came in the form of little cards (SIM cards) that had to be changed when switching the mobile provider. Their size decreased over time from basically a credit card format to the “nano-SIM card of 12.3 mm × 8.8 mm × 0.67 mm (0.484 in × 0.346 in × 0.026 in). Embedded SIMs (eSIMs) “eSIM” stands for “embedded SIM”. Here, the circuit is programmable and already physically embedded in the device itself. The concept was introduced to consumers in 2016 with the Samsung Gear S2 smart watch. It’s the digital version of a SIM card that is embedded directly onto the phone. The great thing about it, with the eSIM, you would no longer be required to keep a physical SIM on the device at all times. You can change your operator at any moment, by simply initiating a remote network switch. And since there’s no physical SIM card, it is all handled electronically. To state that eSIMs are a gamechanger in the field of telecommunications, would be overstating the obvious.
