Kencell=> Celtel=> Zain=> Bharti seems like someone is on a mission to use all the letters of the alphabet in the name of making a name.
The biggest branding mistake this company(for lack of a definate name) made atleast in the Kenyan market its to identify with the rich in its entry stage while their erstwhile competitors went for the bottom end of the pyramid.
That image has proven to be indelible mainly because every Tom Dick and Harry was now in sufferringin-a-coma(safaricom) and it has become difficult to move them away.If Bharti have any hopes of making any profits in Kenya then they push hard for the idea of number portability.
