MILLICOM BUYS OUT THREE MINORITY PARTNERS IN AFRICA

New York and Stockholm - February 1st, 2006 - Millicom International Cellular S.A. ("Millicom") (Nasdaq Stock Market: MICC, Stockholmsbörsen: MIC). Millicom, one of the world's leading cellular operators in emerging markets, today announces that it has completed the buyout of its minority partners in MIC Tanzania Limited and Millicom Sierra Leone Limited. Millicom has also reached agreement to cancel a call option on an equity interest in Millicom Ghana Limited. Following these transactions, Millicom now has 100% ownership in all three operations. These transactions will strengthen Millicom's presence in Africa, where cellular operators continue to see very strong growth. Marc Beuls, Millicom President and Chief Executive Officer said: "These three transactions are consistent with our stated strategy of delivering value to shareholders through increasing our shareholding in our existing operations by buying out minority partners. Africa has once again seen particularly strong growth, and given the relatively low mobile penetration rates in these markets compared to other regions of the world, we have every reason to expect that this will continue in the future." Millicom currently operates in 7 African countries, and also has a significant presence in Latin America and Asia. Millicom has a total population under license of 146 million in Africa, with a weighted average cellular penetration of just 7 per cent in the African countries in which it operates. In December 2005, the company had 2 million subscribers in Africa and this was the fastest growing region for Millicom in 2005, with subscriber growth of 80%. Millicom will disclose details of its operating and financial performance for 2005 when it reports full-year results on February 14th, 2006. Millicom International Cellular S.A. is a global telecommunications investor with cellular operations in Asia, Latin America and Africa.
