The study was conducted in Harare as regards Zimbabwe’s mobile telecommunications sector, examining the influence of a selected factors on consumers’ awareness of corporate social responsibility (CSR) and the effects that CSR awareness has on consumers. The practice of CSR influences a number of business aspects including firm financials, corporate image, corporate reputation and market share. This study has been ignited by the fact that little evidence exist in studies covering the precursors and effects of CSR awareness from the consumers’ perspective. More so, that Zimbabwe’s mobile telecommunications sector is currently the fastest growing sector accompanied with numerous CSR activities. The present study therefore sought to answer the questions which includes; (i) does ethical consumerism, consumer rights awareness, socio-environmental awareness and consumer generosity culture influence consumer awareness of CSR in the mobile telecommunications sector? (ii) what is the effect of age, gender and level of education on consumer awareness of CSR in the mobile telecommunications sector? (iii) what is the influence of consumer awareness of CSR on corporate image, consumer attitude, purchase intention and actual purchase behaviour in the mobile telecommunications sector? (iv) what is the effect of corporate image on consumer attitude in the mobile telecommunications sector? (v) what is the effect of consumer attitude on purchase intention in the mobile telecommunications sector? (vi) what is the effect of purchase intention on actual purchase behaviour in the mobile telecommunications sector? A mixed research study was carried out using a self-administered questionnaire on 1,100 mobile telecommunications sector consumers in Harare, Zimbabwe. Quantitative data was analysed using SPSS with AMOS while qualitative data was analysed using NVIVO. The study results indicate that ethical consumerism, consumer rights awareness, socio-environmental awareness and consumer generosity positively influence consumer CSR awareness while age, gender and level of education do not influence consumer CSR awareness. CSR awareness proves to have a direct influence on corporate image, consumer attitude, purchase intention and not on actual purchase behaviour. The study findings show a direct positive relationship among corporate image, consumer attitude, purchase intention and actual purchase behaviour. The study recognized that respondents are aware of CSR in the form of firm donations, assistance towards social causes, improving the environment, building or renovating facilities, good services, affordable prices and promotional programs. Study results points out that respondents are aware of CSR through platforms such as advertising, sending text messages, firms’ ethical or professional conduct, campaigns and exhibitions. / Business Management / D.
