SGP.32 (eSIM IoT specification)
Updated
SGP.32 is the GSMA technical specification for remote SIM provisioning on IoT devices, built on the requirements of SGP.31. It adds an eSIM IoT remote Manager (eIM), which manages profiles for a whole fleet, and an IoT Profile Assistant (IPA) in the device or in the eUICC, so that devices without a screen or a user can download and switch profiles.
In practice
SGP.32 lets the owner of a fleet choose and change the operator profile of devices remotely, without the operator-driven model of SGP.02 and without the user interaction of SGP.22.
