Millicom International Cellular (MIC) has changed the brand names of its Ghanaian subsidiary Millicom Ghana to Tigo, in line with its strategy of having a single brand name for all its global operations. Previously the GSM operator offered its services as Mobitel/Buzz GSM. The evolution is being billed as more than a simple name change. MIC plans to offer a much improved service offering MMS, GPRS, international calls at local rates and other value added services. Ghana is the third MIC operation in Africa after Senegal and Chad to launch Tigo.
