Many of the poorer countries in the region have vast swathes of their land not covered by GSM or any other connectivity. Sierra Leone, to pick one random example, has no coverage except in and around its capital, Freetown. It is wise not to expect coverage when travelling outside major urban centres, even to some large towns.

Having said that, some vast areas have been covered by pioneering operators who cannot rely on the sort of infrastructure taken for granted in much of the rest of the world - a reliable national electricity grid to power base stations, for example.

South Africa, Swaziland and Tunisia are among the most covered countries geographically, again by GSM. South Africa is the only major country to have launched W-CDMA.

There's no surprise that Tunisia comes among the best networks in Africa as the competition between Tunisiana and Tunisie Telecom was based in three major facts: prices, services and network coverage. i have been traveling the country all around for years in my former job and the cover was always excellent even in the most far places.
