Installation of the trans-Indian Ocean backbone cable (SEACOM) in 2009 has, in theory, made Internet access much more readily available in Dar es Salaam in particular and in East Africa in general. However, roll-out to end-users is currently slow. Telephone-line coverage provided by the Tanzania Telecommunications Company Limited is limited, prices are high, and long contracts are required for purchase of bandwidth for small Internet service providers. The expressed aim of the SEACOM cable is to enable East Africa to develop economically through increased online trading.
