Personalised eSIMs for mobiles and connected devices

It has been announced by STMicroelectronics that they are accelerating progress towards a more convenient and secure connected world, as they become accredited by the GSMA for loading eSIM chips with connection credentials such as certificates and operator profiles before shipping.

The eSIMs, customised with connection credentials, enable smaller form factors, greater security, and increased flexibility. Chip-scale, permanently embedded, and electronically reprogrammable, eSIMs save space inside smartphones for extra features or battery capacity. They also enable different types of connected devices in tiny form factors for an expanding range of markets and applications, such as smart watches and Internet of Things (IoT) devices including smart meters, remote sensors, or gateways.

Building on existing accreditation to manufacture eSIM chips that meet the GSMA's specifications for security and reliability, ST is gaining accreditation for securely applying eSIM personalisation data, according to the GSMA's Secure Accreditation Scheme for UICC Production (GSMA SAS-UP). 

ST can now deliver personalised eSIMs, built around the 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.

Jean-Christophe Tisseuil, GSMA's Head of SIM and eSIM, said: "The SAS-UP accreditation of ST's Rousset (France) production site for the personalisation of WLCSP SIMs and eSIMs is a significant move in driving widespread adoption of trusted eSIM devices by enabling consumer and IoT device manufacturers to implement eSIM in very small form factors. SAS-UP is a first and essential step towards a secure and trusted eSIM market deployment."

Marie-France Florentin, Group Vice President and General Manager of the Secure Microcontroller Division at STMicroelectronics, stated: "The eSIM is an important technological advance that makes it possible to build the connected world of the future, safely. The GSMA's certification scheme governing production and personalisation is critical for its success. Now that ST is accredited to produce and personalise eSIMs before shipping, our customers can benefit from greater efficiency and security throughout the entire supply chain, with all the safeguards and assurances provided by the GSMA's ecosystem."
