Why eUICC SIM OS?

An eUICC OS adds eUICC functionality to a chip, to enable remote SIM provisioning of a cellular device. This means that switching settings or changing carriers on this device can be done remotely, eliminating the need to change the physical SIM. Using an OS that does not support eUICCs will result in a device that is tethered to a single network with a subscription plan that cannot be changed.
