Organizing principles, exchange relationships, and technology affordance of underserved communities in emerging markets are different from privileged communities. This paper investigates knowledge sharing and the use of mobile ICT in a rural farming community in India. Our qualitative field study reveals that value creating and claiming norms are key enablers of knowledge sharing in underserved communities. The findings also identify the importance and challenges of mobile ICT innovations that foster knowledge sharing among dispersed underserved communities. We discuss the implications for theory and suggest a practical guide to enhance knowledge sharing throught mobile ICT innovations in underserved communities.
