STMicroelectronics simplifies IoT deployment with SoftSIM, SGP.32 in-factory provisioning, and Zephyr support for ST87M01

STMicroelectronics has announced new capability options for users of ST87M01 NB-IoT industrial modules, with Onomondo SoftSIM, support for in-factory SGP.32-compliant SIM profile provisioning, and Zephyr ecosystem compatibility.

The Onomondo SoftSIM is a software-based solution running on the ST87M01 processing subsystem which makes unnecessary the use of a physical SIM device. This dramatically accelerates IoT-device deployment and significantly lowers production costs, reduces power consumption to relieve battery demand, and simplifies device-lifecycle and supply chain management.

At Enlit, ST will also showcase how the ST87M01 module lets equipment manufacturers perform in-factory SIM profile provisioning leveraging the SGP.32 standard, which saves stocking SIMs preconfigured for different operators. Downloading and provisioning mobile network operators’ profiles directly on the production line helps simplify inventory management while providing a consistent approach to both in-factory provisioning and remote profile management in the field, using the same SGP.32 framework.

“The latest software-based connectivity and SIM-management options for ST87M01 further extend the flexibility of this family for innovators to tackle the next generation of IoT applications,” said Massimiliano Brambilla, Multisegment ASIC and Application Specific Division (MSA) Division General Manager, STMicroelectronics. “We have also integrated the ST87M01 with the widely adopted Zephyr framework, which makes this module series accessible within a broad open-source embedded ecosystem for all developers.”

The ST87M01 driver for Zephyr is now available through the Zephyr GitHub. It supports connectivity features including UDP, TCP, HTTP, MQTT, and CoAP, as well as GNSS, Wi-Fi positioning, and RSSI display. For developers working with Zephyr-based systems, this support can help streamline integration of the ST87M01 to take advantage of its connectivity and positioning capabilities.

The ST87M01 NB-IoT module family contains multiple variants, compliant with SGP.32 for secure remote SIM provisioning and presenting flexible options including GSMA-certified embedded SIM, GNSS/A-GNSS, Wireless M-Bus, and Wi-Fi positioning. Meeting LTE Cat NB2 Release 15, and with worldwide regional band coverage, the modules are certified in accordance with GCF, EU RED, RED-DA, FCC/ISED, PTCRB, Anatel, and Icasa. Versatile protocol support and ultra-low-power consumption allow extended maintenance-free operation, and the 12.8mm x 10.6mm LGA package is ideal for space-constrained IoT applications.

Visitors to Enlit Europe can see the ST87M01 SIM-provisioning demonstration at STMicroelectronics’ booth, B.b110, VIECON, the Vienna Congress & Convention Center, November 10-12.

ST will also present the ST87M01 and a selection of IoT solutions at electronica 2026, Messe Műnchen, Munich, November 10-13, Hall C3/booth 101.
