You notice that some of those companies including those you listed have their own consumer niche.
Also note that the market is just too enormous for one player to dominate.
Safcom can succeed on ubiquitous infrastructure but will flop on pricing if I take the current example of 'zambaza bundles' and 'post paid tarrifs'
Safcom will likely sell internet bundles while some players have flat monthly charges.
Price wars will definitely hurt all players.
My prediction is whoever takes the Citizen model to provide local content of acceptable quality plus offer a VAS in the form of internet could stand to be counted
