SGP.42 (SIM Alliance Specification for Remote SIM Provisioning – IoT) is a specification from the GSMA designed for Remote SIM Provisioning in IoT devices. It defines the architecture and processes that allow eSIM profiles to be securely downloaded, updated, or deleted over-the-air. This makes it possible to change mobile network operators without replacing the SIM card physically.
The standard focuses on the needs of IoT deployments. It supports devices with limited user interfaces, low data rates, and long lifespans. SGP.42 enables remote connectivity management for sensors, trackers, meters, and industrial equipment deployed in hard-to-reach areas.
SGP.42 works by setting clear rules for communication between three key components:
By using SGP.42, organizations can simplify logistics, reduce operational costs, and extend device lifecycles. They can also respond faster to changes in network availability or business requirements.
SGP.42 makes large-scale IoT connectivity more flexible, secure, and efficient through standardized remote SIM provisioning.
