The embedded Universal Integrated Circuit Card (eUICC) is the software component of an embedded SIM (eSIM). eUICC uses a global GSMA-sponsored standard universally held by mobile operators. This standard is what makes eSIM technology so versatile.

Moreover, eUICC reduces the manual processes associated with continuously swapping out SIMs as one goes from network to network. It improves connectivity management of IoT deployments at scale.

eUICC is a central IoT platform technology. IoT device connectivity managers can provision and manage their device’s mobile connection details over the air (OTA). Nevertheless, eUICC implementation can be complex, depending on the use case. There are several critical considerations businesses should have in mind when approaching their next project.
