The aim of this study is to examine the factors that influence customer loyalty in the telecommunication industry of Zimbabwe. Increased competition in the telecommunication industry has motivated the service providers to review the quality of their services and to build customer loyalty platforms for the purpose of customer retention. Service quality is the most important determinant of customer loyalty. Strong interpersonal relationships between service providers and customers are the way to build customer loyalty, even when competitors try to win them over with lower prices. The study uses the structured questionnaire to collect data from a sample of 200 customers of the mobile telecommunication industry. Purposive sampling techniques were employed in the study. A conceptual framework was constructed in order to provide a platform for the creation of relevant hypothesis. Thus several hypotheses were generated and tested using one-way ANOVA, and multiple regression analysis. The dependent variable was customer loyalty, whereas the independent variables were, service quality, customer satisfaction, trust, corporate image and switching cost. The results of the study revealed that service quality, customer satisfaction, trust and corporate image have some degree of relationship with customer loyalty whereas switching cost did not have any significant degree of relationship with customer loyalty.
