Vodacom Group Limited (Vodacom) is an African mobile communications company, providing voice, messaging, data and converged services to over 55 million customers. From its roots in South Africa, Vodacom has grown its operations to include networks in Tanzania, the Democratic Republic of Congo, Mozambique, and Lesotho and provides business services to customers in over 40 African countries such as Nigeria, Zambia, Angola, Kenya, Ghana, Côte d'Ivoire, and Cameroon. It was owned on a 50:50 basis by the South African telecommunications group Telkom and the British mobile phone operator Vodafone. On 6 November 2008 Vodafone announced that it had agreed to increase its stake to 65%, and Telkom said that it would spin off its remaining holding by listing it on the Johannesburg Stock Exchange. On April 1, 2011, Vodacom officially unveiled its new change in branding from blue to red, using the same style as its parent company, Vodafone.
