Internally Displaced People (IDP) have received less attention in ICT4D research. This study examines how IDP in Africa use mobile phones to enhance their social inclusion. We employed Sen's Capability Approach as the theoretical lens and a qualitative case study as a methodology. Qualitative data obtained from 21 conflict-induced IDP in Nigeria suggests that mobile phones serve not only as a self-help commodity to overcome disconnection from their communities but also a means to enhance their individual and collective capabilities, which in turn fosters their social inclusion. However, generating these capabilities depend on the personal, social, and environmental experiences of IDP. With these findings, the study offers contributions to theory, research, and practice.
