perceptions and experiences of customers, to find the linkage between mobile telecommunication service quality attributes, customer satisfaction and customer loyalty in mobile telecommunication service sector Based on the mobile telecommunication service quality model suggested by Lee, Lee and Freick (2001), six main dimensions (call quality, pricing structure, mobile devices, value-added services, convenience in procedures and customer support) were used to find out the relationship among mobile telecommunication service quality, customer satisfaction, and customer loyalty All the data were collected through questionnaires; the sample size of 350 mobile customers was drawn from different mobile carriers in Ho Chi Minh City Descriptive statistical approach, multiple linear regression, Anova were then used to describe and analyze these six dimensions and take them into the involvement with customer satisfaction and loyalty The results show that six dimensions above are positively related to customer satisfaction and customer satisfaction is positive related to customer loyalty Customer support demonstrates the highest positive correlation with customer satisfaction while pricing structure demonstrates the lowest positive correlation with customer satisfaction Keywords: Mobile, Service quality, Customer satisfaction, Customer loyalty, Call quality, Pricing
