To overcome this challenge, Hildebrand partnered with 1NCE, for Narrowband-IoT (NB-IoT) connectivity solution. Right now, the company utilizes 5500+ industrial-grade SIM and eSIM chips provided by 1NCE. NB-IoT's signal penetration capabilities enabled Hildebrand's smart devices to function optimally even in the underground stations, traditionally known as connectivity dead zones. Additionally, 1NCE's user-friendly portal provided Hildebrand with the ability to remotely monitor and troubleshoot the system, ensuring minimal downtime and continued reliability of their metering services. This resulted in a significant improvement in operational efficiency, with a notable 75% reduction in eSIM/SIM related fees.
