Mobile telephony forges the future. In many African countries, the number of smartphones has increased rapidly over the past few years. Already 15 years ago, many countries bypassed the expensive and time-consuming expansion of the landline network to focus on upgrading mobile technology. This technology jump is vital for local and regional economic development. Today eight of ten people have a mobile phone contract and even most of the rural areas are connected to the mobile phone network. DEG has made a vital contribution to this expansion, e.g. by financing mobile operators. But also the number of new apps is on the rise. Particularly Kenya’s capital, Nairobi, is home to a vibrant and growing app programmer scene.
