What is SGP.32

Quick definition

SGP.32 is the GSMA Remote SIM Provisioning standard built specifically for IoT, published in 2023. It supersedes SGP.02 (M2M) and removes the dependency on SGP.22 (Consumer) for headless devices. It introduces the IPA (IoT Profile Assistant) and a Pull model where the device requests profiles by country or event.

What changes versus SGP.22

SGP.22 assumes the user scans a QR or types an activation code. Impossible on IoT (no screen on a sensor). SGP.32 introduces the eIM (eSIM IoT Manager), a server that points the device at the right SM-DP+, and the IPA inside the module that runs the download with no human in the loop.

When it lands in silicon

SGP.32-certified modules started shipping in late 2024 (Quectel, Telit, u-blox). By 2026 it is the default expectation for any new IoT deployment. Legacy devices will keep running SGP.02 for years.

FAQ

Do I have to migrate my SGP.22 eUICCs to SGP.32?+

No, not forcibly. Deployed SGP.22 keeps working. For new designs from 2025 onward, SGP.32 is the right choice.

What infrastructure does SGP.32 need?+

An eIM (eSIM IoT Manager), a compatible SM-DP+, and modules with IPA. The benefit: provisioning no longer requires human interaction.
