ST4SIM-300: Flexible Embedded SIM to Support Bulk IoT Device Management


STMicroelectronics has introduced the ST4SIM-300, the first embedded SIM in the industry to meet the incoming GSMA standard for eSIM IoT deployment. Also known as SGP.32, the new standard introduces special features to facilitate managing IoT devices connected to cellular networks. The new eSIM conforms to the latest 5G standard and facilitates deploying devices that have a limited user interface and deploying low-power wide-area network (LPWAN) devices. ST is sampling ST4SIM-300 eSIMs in various form factors, including wafer-level chip-scale packages (WLCSP) suitable for smart meters, GPS trackers, asset monitors, remote sensors, medical wearables, and similar devices.

Unlike existing eSIM machine-to-machine (M2M) and eSIM Consumer specifications, eSIM for IoT (SGP.32) is created for the needs of today’s IoT deployments. ST’s ST4SIM-300 supports features including greater automation of remote SIM provisioning (RSP), easily managing SIM profiles for large fleets of devices, and remote switching between network providers that eliminates physical SIM card swaps. Built with an EAL6+ certified ST secure microcontroller, the ST4SIM-300 is architected for security from the ground up. Compatible with GSMA IoT SAFE applet the eSIM facilitates adding secure element features for end-to-end communication and supports scalable security by design for creators of IoT devices.
