Purpose: The study examined the influence of corporate reputation, customer trust, and perceived service credibility on consumer purchase intention in Kenya’s telecommunications industry. It aimed to understand how these factors shape consumer decisions in a competitive market.

Methodology/Design: A quantitative research design guided by the positivist philosophy was employed. Primary data were collected from 500 active mobile subscribers using a structured questionnaire. Simple random sampling was applied, and the measurement instruments were validated using factor analysis. Structural Equation Modeling (SEM) was used to test the hypothesized relationships.

Findings: The results indicated that corporate reputation significantly influenced consumer purchase intention. Customer trust was found to mediate the relationship between corporate reputation and purchase intention, while perceived service credibility also had a positive effect on consumer behavior. All three hypotheses were supported, demonstrating that reputation, trust, and credibility are critical drivers of purchase intention in Kenya’s telecom sector.

Implications: The findings highlight the importance for telecom firms to build a strong reputation, enhance customer trust, and ensure credible service delivery. Managers can use these insights to design strategies that strengthen consumer confidence, loyalty, and long-term engagement. Policymakers can also develop regulations promoting transparency, ethical conduct, and service reliability.
