STMicroelectronics adds SoftSIM, SGP.32 provisioning and Zephyr support to ST87M01

STMicroelectronics is expanding its ST87M01 NB-IoT module family with Onomondo SoftSIM, in-factory SIM profile provisioning based on SGP.32 and Zephyr support. The updates are aimed at cutting deployment friction, simplifying inventory and giving developers more connectivity options for industrial IoT devices.

Why it matters: - STMicroelectronics is trying to remove three common IoT deployment bottlenecks at once: physical SIM handling, operator-profile provisioning and software integration. - The changes are designed to lower production complexity, reduce power use and make the ST87M01 easier to adopt in industrial and space-constrained devices.

What happened: - STMicroelectronics announced new capability options for ST87M01 NB-IoT industrial modules. - The additions include Onomondo SoftSIM, support for direct in-factory SGP.32-compliant SIM profile provisioning and compatibility with the Zephyr ecosystem. - The company will demonstrate SIM-profile provisioning at Enlit Europe 2026.

The details: - Onomondo SoftSIM runs as software on the ST87M01 processing subsystem and removes the need for a physical SIM device. - STMicroelectronics says the software-based approach can accelerate IoT-device deployment, lower production costs, reduce power consumption and simplify device-lifecycle and supply-chain management. - STMicroelectronics will show how equipment manufacturers can provision SIM profiles in factory using the SGP.32 standard. - The SGP.32 approach lets manufacturers download and provision mobile network operator profiles directly on the production line. - The same SGP.32 framework supports both in-factory provisioning and remote profile management in the field. - The ST87M01 driver for Zephyr is available through the Zephyr GitHub. - The Zephyr driver supports UDP, TCP, HTTP, MQTT and CoAP, plus GNSS, Wi-Fi positioning and RSSI display. - The ST87M01 NB-IoT module family includes multiple variants compliant with SGP.32 for secure remote SIM provisioning. - The family also offers GSMA-certified embedded SIM, GNSS/A-GNSS, Wireless M-Bus and Wi-Fi positioning options. - The modules meet LTE Cat NB2 Release 15 and offer worldwide regional band coverage. - Certifications listed for the module family include GCF, EU RED, RED-DA, FCC/ISED, PTCRB, Anatel and Icasa. - The modules use a 12.8mm x 10.6mm LGA package for space-constrained IoT applications.

Between the lines: - The announcement shows STMicroelectronics is bundling connectivity, provisioning and software support into one module family instead of forcing developers to stitch together separate solutions. - Support for both factory provisioning and remote management suggests a push toward a more unified SIM lifecycle across manufacturing and deployment. - Zephyr support broadens the module's appeal among developers using open-source embedded systems.

What's next: - Visitors to Enlit Europe 2026 can see the ST87M01 SIM-provisioning demonstration at STMicroelectronics’ booth B.b110 at VIECON, the Vienna Congress & Convention Center, from November 10-12. - STMicroelectronics will also present the ST87M01 and other IoT solutions at electronica 2026 in Munich from November 10-13 at Hall C3, booth 101. - More information is available at STMicroelectronics' NB-IoT page.

The bottom line: - STMicroelectronics is positioning the ST87M01 as a more complete NB-IoT platform for manufacturers that want simpler SIM management, easier software integration and lower deployment overhead.
