SIMs & embedded SIMs solutions to secure your cellular connectivity
SIM and embedded SIM (eSIM) solutions provide secure cellular connectivity and ensure its seamless deployment, thus improving day-to-day user experience. From consumer, M2M and industrial applications including asset tracking and smart metering to automotive solutions such as in-vehicle emergency calls (eCall), SIMs and eSIMs simplify device monitoring and contribute to the digital transformation of a wide range of markets. With more than 1.5 billion of ST33 deployed today, ST positions itself as the industry leader for eSIM solutions.

STMicroelectronics Becomes First Chip Maker Accredited by the GSMA to Personalize eSIMs for Mobiles and Connected IoT Devices
Building on existing accreditation to manufacture eSIM chips that meet the GSMA’s specifications for security and reliability, ST is speeding ahead of other chip makers by gaining further accreditation for securely applying eSIM personalization data, according to the GSMA’s Secure Accreditation Scheme for UICC Production (GSMA SAS-UP).
ST can now deliver personalized eSIMs, built around the proven ST33 secure microcontroller, directly to customers’ production facilities, ready to use with no further programming required. Equipment OEMs, mobile network operators, and SIM operating-system (OS) vendors can thus enjoy greater convenience, economy, and business efficiency by streamlining the eSIM supply chain to save handling overheads and reduce time to market. The eSIMs, customized with connection credentials, enable smaller form factors, greater security, and increased flexibility.
