What is an eIM in eSIM IoT?
eIM (eSIM IoT Remote Manager) is a component introduced in SGP.31/32 that enables remote profile state management for IoT device fleets. It works with the IPA (IoT Profile Assistant) to manage eSIM profiles without requiring user interaction.

What is the difference between SGP.22 and SGP.32?
SGP.22 is the GSMA consumer eSIM standard using QR codes and apps. SGP.32 is designed for IoT devices, enabling automated provisioning at scale 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.
