Currently, almost every nation struggles with the idea of smart cities to adopt city management. Several previous studies have produced many models to measure the quality of ISS. In previous studies, service quality and experience in smart city applications were measured and assessed. However, a few works still examine the service quality of the Smart District model, which varies quite strongly from the overall smart city concept. This research aims to assess the service quality of mobile-based smart regions or districts. The model and approach used are the E-Government Adoption Model (GAM). This model is a development of the previous model, such as technology adoption model (TAM), diffusion of innovation theory (DOI), and theory of prohibited behavior (TPB). Two hundred eighty-three participants interviewed succeeded in collecting data collection using online and offline survey methods, data processing using AMOS 24.0 software. Research findings show that the variables in the GAM model reflect a positive relationship and are significant in terms of quality measures for intelligent district services. This study contributes to explain the effective use of intelligent regional mobile devices. This research shows that governments and policymakers focus more on important issues affecting the quality of smart cellular service.
