Mobile networks have developed rapidly in recent years in areas previously unserved Africa. Alongside the European Orange, Vodafone and Tigo (Millicom), there is South Africa's MTN and Zain and Moov from Middle East. Their strategy aims at reducing prices to increase market share, even though investment in the development of networks is slowing under the impact of the financial crisis. A factor key to the communications revolution in Africa lies in the reduction of roaming charges - which is to apply a local rate to a user even if abroad. Regional integration will increase as these strategies propagate to other operators and ultimately eliminate the price differences from one country to another.
