Abstract— Narrowband Internet of Things (NB-IoT) has emerged as a key enabler of massive machine-type communication (mMTC) within the 3GPP family of cellular technologies. Its ability to provide wide-area coverage, deep penetration, and ultra-low power consumption makes it ideally suited for smart metering, smart cities, agriculture, healthcare, and logistics. This article provides a comprehensive overview of NB-IoT technology, its modulation schemes, frequency operation, and comparative advantages over other LPWAN technologies. A detailed discussion of the STMicroelectronics ST87M01 NB-IoT device is provided, highlighting its architecture, security capabilities, and optimized performance for embedded IoT systems. Furthermore, the article introduces the STEVAL-874SIMCB evaluation board, which integrates the ST87M01 with both embedded eSIM (ST4SIM-300) and external SIM support, offering developers a versatile platform for rapid prototyping. By examining technical strengths, use cases, and deployment scenarios, this work demonstrates how NB-IoT and eSI...
