STMicroelectronics ST4SIM-300 eSIM for IoT connectivity

STMicroelectronics has introduced the ST4SIM-300, an embedded SIM that meets the incoming GSMA standard for eSIM IoT deployment. Also known as SGP.32, the standard introduces special features to facilitate managing IoT devices connected to cellular networks. Unlike existing eSIM machine-to-machine (M2M) and eSIM Consumer specifications, it has been created for the needs of today’s IoT deployments.

The eSIM supports features including 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. It 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.

Featuring an EAL6+ certified ST secure microcontroller, the eSIM is built for security from the ground up. Compatible with the GSMA IoT SAFE applet, it facilitates adding secure element features for end-to-end communication and supports scalable security by design for creators of IoT devices.

The eSIM is designed to enhance flexibility, ease network provider switching and simplify the management of large numbers of connected devices. In a more connected and secured world, it will help seamlessly track assets across the globe, connect smart devices to the cloud and securely handle data from billions of devices. ST is sampling the product 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.
