TOKYO - April 3, 2025 - Internet Initiative Japan Inc. (TSE Prime: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced that the highly functional, power-efficient nRF9151 communication module from Nordic Semiconductor (hereinafter, “Nordic”), a market leader in the field of IoT-related wireless semiconductors, now supports IIJ’s SoftSIM. The nRF9151 communication module is a successor to the earlier nRF9160, offering the same functionality in a 20 percent smaller package and reducing peak power consumption by up to 45 percent. It is ideal for IoT devices such as wearable devices and smart sensors, with board area constraints and the need for low power consumption.

SoftSIM stores a communication profile in the communication module, enabling connection to a mobile network without a physical SIM. Eliminating the need for a SIM card slot or socket makes it possible to create smaller communication devices with lower failure rates and improved durability, while doing away with concerns about SIM card theft. Not having to equip a device with a SIM card or chip SIM reduces the burden of parts management and operation, and enables cost reductions.

IIJ has been providing SoftSIM solutions since 2019 and is the only SoftSIM provider in Japan. The collaboration with Nordic began in 2024.(*)
Expanding the SoftSIM support lineup with nRF9151, featuring a more compact size and lower power demands than the nRF9160 module, broadens the options available to IoT device developers and manufacturers.

The module will be showcased at IIJ's booth during the Kansai Robot World 2025, held from June 5 to 6, 2025.
