The IoT market has entered a new phase: Giesecke+Devrient Mobile Security (G+D) is introducing its market-ready Integrated SIM (iSIM) solution for the IoT, based on a module from Telit Cinterion. With a state-of-the-art iSIM operating system for a chipset from Sony Semiconductor Israel (Sony), G+D offers a solution that has been specifically developed and optimized for use in NB-IoT (Narrowband IoT) applications.

The iSIM is central to improving the connectivity, security, and sustainability of next-generation IoT devices. To accelerate iSIM innovation, G+D has now partnered with Telit Cinterion, a global leader in IoT enablement products, services, and solutions, to develop a new solution for NB-IoT use cases such as smart metering, smart agriculture, asset tracking, and many more.

A key component of the solution is the iSIM (integrated SIM) or iUICC (integrated universal integrated circuit card), which, unlike insertable SIM cards or permanently soldered eSIMs, is a tamper-resistant element (TRE) within a system-on-a-chip (SoC). This means that the iSIM is an isolated hardware component that is combined with a baseband chipset to form a single connectivity module. This design gives the iSIM numerous advantages in areas such as energy consumption, costs, sustainability, and security. The small space requirement enables the production of small, light, and therefore cost-effective devices. In addition, iSIMs also meet high sustainability requirements.

A high level of security is provided by the isolated hardware in combination with G+D’s secure and certified iSIM operating system. Through cooperation with a leading global mobile network operator, G+D has now successfully qualified the iSIM operating system OS on the Cinterion NE310L2 NB-IoT module, which is based on Sony’s Altair ALT1255 chipset. This system can now be offered to OEMs. This makes G+D Mobile Security one of the first providers of an operating system for Sony’s energy-saving and cost-optimized Altair chipset that is specifically tailored to NB-IoT use cases—an important milestone for G+D.

G+D’s secure iSIM OS is platform-independent and ensures optimal functionality on a variety of iSIM-enabled chipsets, including Sony’s next-generation LTE-M and NB-IoT chipsets and Altair’s ALT1250, ALT1255, and ALT1350 models. This compatibility underlines G+D’s commitment to developing solutions that can be used for a wide range of IoT applications and devices.

“G+D is investing heavily in the research and development of iSIM technology. In close cooperation with industry partners, we want to continue to drive iSIM innovation. The successful development and qualification of an optimized iSIM OS for a cost-effective and commercially available NB-IoT product is an outstanding example of practical implementation,” emphasizes BeeGek Lim, Global Vice President, Head of Business Line Digital Offerings at G+D. “In general, one of our main concerns is to provide secure solutions for a wide range of IoT applications and devices so that users can exploit the full potential of the IoT with flexible and cost-optimized connectivity.”

“We are proud to be part of the collaboration between G+D and Sony Semiconductor Israel in this innovative technological development,” says Jose Sanchez, Senior Director Product Management, IoT Connectivity & Services at Telit Cinterion. “We look forward to working with our partners to remain at the forefront of iSIM technology for the Internet of Things in the years to come.”

“We are also pleased to work with Telit Cinterion and G+D to integrate iSIM into our LPWA products. The ALT1255 is the first NB-IoT chipset on the market to support iSIM,” affirms Dima Feldman, VP of Product Management and Marketing at Sony Semiconductor Israel. “iSIM enables connectivity without additional physical hardware, which simplifies the solution, eases the logistical onboarding process and makes it more cost-effective—a key advantage for the industrial IoT market.”
