STMicroelectronics certifies ST4SIM-300 eSIM for IoT applications

STMicroelectronics has achieved GSMA SGP.32 eSIM IoT specification certification for its ST4SIM-300 embedded SIM (eSIM), enabling interoperability with cellular networks and IoT service platforms globally. The certification supports remote provisioning and network provider switching for IoT devices.
The ST4SIM-300 is one of the first eSIMs certified for SGP.32, designed for IoT devices with limited user interfaces or connectivity, such as those using narrowband communication. SGP.32 features include bulk provisioning for managing large device fleets, SMS-free provisioning, and a lightweight profile template for efficient downloads.
The eSIM targets applications in healthcare, energy management, and logistics, supporting devices like mobile asset trackers, smart meters, and healthcare equipment. It operates in industrial-grade conditions with a temperature range of -40°C to 105°C and can function as a secure element with the GSMA IoT SAFE applet. The ST4SIM-300 is available in multiple form factors, including solderable chip-scale packages and removable cards (2FF, 3FF, 4FF), as well as 6mm x 5mm DFPN8 and WLCSP24 packages.
Built on ST’s ST33K1M5M secure microcontroller with an Arm Cortex M35P core, the eSIM supports advanced RSA and ECC cryptography, complies with Common Criteria EAL6+, and holds GSMA eSA certification based on SGP.25 v2.1 Protection P...
