According to data published by the telecoms regulator, the National Communications Authority (NCA), Ghana was home to more than 16.779 million registered mobile phone subscriptions at 31 October 2010, up from around 16.031 million in January, vastly outstripping main lines in service which stood at 317,216 at the same date. It must be noted, however, that the figure includes a number of inactive users and the active base is around 400,000 lower than the headline total. The NCA’s data shows that MTN Ghana led the mobile market by a fair margin at the start of November 2010 with 8.489 million customers, a market share of 49.66%, ahead of Millicom Ghana’s Tigo unit which had 3.870 million users. Meanwhile, third placed operator Vodafone (Ghana), the mobile arm of the national fixed line PTO, had amassed 2.582 million mobile users, equivalent to a market share of 15.10%. Airtel Ghana, which launched commercial services in December 2008 under its previous brand Zain, had a 9.36% market share (1.600 million), while Kasapa Telecom – recently rebranded as Expresso – had 236,605 users, compared with a low of 204,238 in June this year.
