Telkom connects the people that keep Kenya on the move.
It does this by providing integrated telecommunications solutions to individuals, Small and
Medium-sized Enterprises (SMEs), Government and large corporates in Kenya, drawing from a
diverse solutions suite that includes voice, data, mobile money as well as network services.
Powered by its vast fibre optic infrastructure, it is also a major provider of wholesale, carrier-to-
carrier traffic within the country and the region.
Telkom is building on a strong, consumer-centric ethos that is committed to providing innovative,
accessible and refreshingly simple communications solutions that suit customers’ everyday
communication needs.
Established as a telecommunications operator in April 1999, Telkom is 60 per cent owned by
Helios Investment Partners, with the remaining stake held by Kenyans through the Government
of Kenya.
