In recent years, research has revealed the importance of Corporate Social Responsibility (CSR) and its significant impact on organizational performance. Also, scholars have recognized that consumers’ attitudes and behaviors towards products and organizations are greatly influenced by organizational CSR programs and strategies. Consumers are generally recognized as one of the primary stakeholders of organizations in the marketing exchange process hence their perceptions of CSR are important since stakeholders’ perceptions influence organizations' CSR practices. Given the vibrant nature of service industry in general and its telecommunication sector in particular, this study applied the Analytic Hierarchy Process (AHP) Model to determine consumers’ perceptions of the CSR activities and strategy for organizations in the Nigerian Global System for Mobile (GSM) telecommunication industry. To achieve these aims, a sample of 600 consumers of the four major operators in the Nigerian GSM telecommunication industry (MTN/AIRTEL/GLO/ETISALAT) were drawn from tertiary institutions using the convenience sampling technique. The data obtained was analyzed using descriptive statistics and the Expert Choice software. Findings show that the CSR activities consumers feel organizations in the Nigerian GSM telecommunications industry should place high priority on are: Organizing or participating in public welfare activities, Encouraging employee’s voluntary welfare programs, Improving employee welfare (facilities and benefits), Active contribution of tax to government and Contribution to cultural and literacy programs.
