This document discusses the various ways that cell phones and text messaging are being used across Africa to improve government, healthcare, banking, education, commerce, and social connections. Key uses include e-government services, anonymous medical consultations, branchless banking like M-PESA, distance education via blogs and messages, and improving literacy. Cell phone ownership has grown enormously, from 5% to 60% of populations having access since 1999. Projects in some villages have doubled agriculture yields, reduced child mortality by 30%, and more than tripled cell phone ownership over 5 years.
