Kigen outlines SGP.22 v2.7, SGP.32 v1.3 and LITE4

TL;DR: Kigen said GSMA published SGP.22 v2.7 for consumer eSIMs in April 2026 and SGP.32 v1.3 for IoT eSIMs in May 2026, and said GSMA's LITE4 interoperability event for SGP.32 will run from 26 to 30 October 2026 in La Ciotat, France, hosted by Thales.

Kigen said GSMA's current eSIM standards are grouped into M2M, consumer and IoT families, with SGP.01/02 covering M2M, SGP.21/22 covering consumer devices, and SGP.31/32 covering IoT. Kigen said SGP.32 builds on SGP.22 and adds an eSIM IoT Manager, or eIM, and an IoT Profile Assistant, or IPA, for devices with limited user interaction or limited bandwidth.

Kigen said the latest published versions are SGP.22 v2.7 for consumer devices and SGP.32 v1.3 for IoT devices. Kigen said its latest GSMA eSA-certified eSIMs support both versions, and that its portfolio on Infineon's TEGRION SLx22 family includes SLC22 for consumer devices, SLM22 for industrial IoT and SLI22 for automotive.

Kigen said recent standards changes include stronger isolation between third-party applets on the eUICC, tighter controls on test profiles, restrictions on applet installation in test profiles, and coverage for eUICC OS updates. Kigen said SGP.32 also keeps fallback, rollback and emergency profiles from M2M deployments and standardizes retrieval of connectivity settings such as the APN from the active profile.

Kigen said GSMA is standardizing in-factory profile provisioning as SGP.42, expected in 2027. Kigen said LITE4 will test whether independently developed SGP.32 implementations interoperate in practice, and said OEMs should review the named eUICCs, eIMs, devices, SM-DP+ platforms, specification versions, tested profile operations, download path support, IPA location, and recovery behavior behind any interoperability claim.
