Vodacom provides coverage to Mount Kilimanjaro, which was the highest point in the world to be covered by GSM, until Axiata (through its subsidiary Ncell) provided coverage at the top of Mount Everest, the highest point in the world. Vodacom was aided by its optimistic advertisements at the early stages of the democratic South Africa, including the yebo gogo campaign which is still in effect today in Africa. Vodacom is the leading cellular network in South Africa with an estimated market share of 58% and more than 103 million customers across Africa.
