This article examines measures to extend the service life of devices by implementing a comprehensive preventive maintenance plan. The aim is to ensure the reliability and usability of devices to provide high-quality services to users of mobile communication infrastructure within the "M-Government" environment of mobile communication companies. Additionally, it explores ways to increase customer numbers and support service-providing companies by studying customer relationships based on an analysis of customer satisfaction, retention, loyalty, acquisition, and attrition criteria. The article also emphasizes the importance of providing analytical information to mobile company management about each of the key indicators influencing customer relationships
