Embedded SIMs (eSIM), which refer to SIM cards that are embedded into devices, have been around for well over a decade. The genesis of eSIMs was in response to the complexity of managing physical SIM cards on remote machines and devices which were seldom serviced or inspected once deployed. In many ways eSIMs accelerated the IoT era by simplifying connectivity management for remote devices.  

Thanks to the pervasiveness of IoT applications, the adoption of eSIMs soared across  enterprises and businesses worldwide.
