As per the Nigerian Communications Commission, as of January 2021, the number of third and fourth-generation telecom towers deployed in Nigeria has grown by 73.2%. Also, global tower companies have been expanding their presence in the region, through strategic collaborations, due to the growing number of opportunities presented. In January 2020, American Tower acquired Eaton Towers in a deal that included towers across five African countries. While American Tower already had a presence in Africa, the acquisition was a significant deal, demonstrating the types of investment being made in the region, particularly in the tower market. According to estimates by TowerXchange, there are roughly 25,767 towers in South Africa, serving 97mn SIMs, making it one of Africa's best-covered markets. Five MNOs operate within the South African market, mainly MTN, Vodacom, Telkom, Cell, and C-and Rain. Cell C is in the process of shutting down its network and switching to a roaming agreement with MTN.
