Mobile phones have become ubiquitous in Sub-Saharan Africa and are having a significant developmental impact. They are bringing people together through communication networks and playing a crucial role in every socio-economic sector. Mobile phones have equipped millions of people with the means to connect digitally and be less isolated. Their presence is affecting key socio-economic development activities and they should be seen as an essential tool for development. The design of mobile phones and services for African communities should prioritize meeting needs over profits to maximize their developmental impact.
