Factors influencing consumers’ loyalty in the use of mobile telecommunication services: the case study in Vietnam

Purpose The research aimed to identify factors influencing customer loyalty in the use of mobile telecommunication services in Vietnam, focusing on two dimensions “attitudinal loyalty” and “behavioral loyalty.” Design/methodology/approach Based on survey data collected from 820 in two of Vietnam’s major cities users, Hanoi and Ho Chi Minh City, the data were processed using SPSS and AMOS software. Findings The study identified four factors affecting customer loyalty to mobile telecommunication services, with perceived service quality directly impacting both attitudinal and behavioral loyalty. Corporate image and perceived switching costs influenced attitudinal loyalty, while trust affected behavioral loyalty. Moreover, perceived service quality indirectly influenced attitudinal loyalty through corporate image and perceived switching costs. Research limitations/implications The study only focuses on a limited number of factors influencing mobile telecommunications service user loyalty, its restricted geographical sample from only Hanoi and Ho Chi Minh City, and the simplification of perceived switching costs without considering their various components, such as psychological, financial and procedural costs, which could provide more comprehensive experimental and theoretical insights. Practical implications The study reveals that customer loyalty in Vietnam’s mobile telecommunications sector is linked to the relationship between attitude toward the service provider and continued usage behavior, categorizing customer groups into genuine loyalty, latent loyalty, feigned loyalty and disloyalty. It suggests that service providers should focus on improving service quality and cultivating a positive, transparent corporate image to bolster customer trust, foster stable relationships and remain competitive in the market. Originality/value The research model combines Oliver’s (1999) theory of loyalty with Aydin and Özer’s (2005) research model, focusing on perceived service quality, corporate image, trust and perceived switching costs, examining their relationships with both behavioral and attitudinal loyalty simultaneously.
