What is the difference between SGP.22 and SGP.32?
SGP.22 is the GSMA standard for consumer devices (smartphones, tablets) with user interaction via QR codes or carrier apps. SGP.32 is designed for IoT devices that are UI-constrained or network-constrained, enabling automated provisioning at scale without human interaction.

What is an eIM in eSIM IoT?
eIM (eSIM IoT Remote Manager) is a SGP.31/32 component enabling remote profile management for IoT fleets. It works with IPA to manage eSIMs without user interaction.
Is SGP.32 backward compatible with SGP.02 (M2M)?
No, SGP.32 is not backward compatible with SGP.02. However, SGP.32 reuses SM-DP+ infrastructure from SGP.22, simplifying adoption for operators with consumer eSIM support.
