For small scale deployments, it is a very simple task to physically swap out your SIM cards. However, most large-scale connectivity deployments aren’t as accessible. SIMs are often embedded in devices and scattered across many different remote or hard to reach locations, spanning multiple countries or continents. eSIM removes the necessity for site visits when SIMs need to be swapped, enabling your entire M2M SIM estate to be reprogrammed Over-The-Air (OTA). So if you need to change tariffs or take advantage of a different MNO’s coverage, you won’t have to physically touch your hardware; it can all be achieved remotely.
