Millicom International Cellular S.A. Announces Results for the Quarter Ended March 31, 2004

NEW YORK, LONDON, STOCKHOLM, Sweden, BERTRANGE, Luxembourg, April 20, 2004 (PRIMEZONE) -- Millicom International Cellular SA, the global telecommunications investor, today announces results for the quarter ended March 31, 2004.

Marc Beuls, MIC's President and Chief Executive Officer stated:

"We have changed our financial reporting to reflect the five operational clusters in the group which are South East Asia, South Asia, Africa, Central America and South America. Countries within a cluster have historically shown similar developments and breaking down the numbers in this way provides greater transparency and enables our shareholders, bondholders and analysts to gain a better understanding of the trends we see in certain parts of the company."

"MIC has had a buoyant start in 2004, building on the growth seen last quarter, by producing increases in revenues and EBITDA of 54% and 55% respectively over the first quarter of 2003. Our African operations in particular continued to show very impressive growth with revenues up 76% and EBITDA up 92% year on year, fuelled by annual total subscriber growth of 81%. Asia continued to perform well and we are encouraged by definite signs of recovery in South America. Our priority for 2004 is to accelerate the growth of our existing operations, whilst seeking opportunities in adjacent markets. Our current licence renewals are progressing well. We signed a Memorandum of Understanding in Vietnam and, in Pakistan, our licence extension has been confirmed and negotiations continue with the Ministry of Telecoms regarding final terms."
