The 2Africa project is part of a joint enterprise by China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone, and the West Indian Ocean Cable Company (WIOCC).

The 37,000km-long 2Africa cable will feature around 21 landing points in 16 African countries and will carry three times the total network capacity of all the submarine cables currently serving the continent.
