New York and Luxembourg -- July 9, 2003 -- Millicom  International Cellular S.A.
(MIC) (Nasdaq  Stock  Market:  MICC),  the global  telecommunications  investor,
announced  today that in the second quarter of 2003 its worldwide  operations in
Asia,  Latin  America*  and Africa added  223,121 net new cellular  subscribers,
resulting in an increase of over 5% from the total subscribers recorded at March
31 2003. On a proportional basis, 121,352 subscribers were added.

At June 30, 2003, MIC's worldwide cellular  subscriber base* increased by 28% to
4,471,835 cellular subscribers from 3,483,573 as at June 30, 2002.  Particularly

subscribers in the quarter, whilst MIC Africa recorded its best quarterly result
for 2 years, adding 20,955 subscribers. Subscriber numbers for MIC Latin America

increase of 25% from the 2,472,960 proportional subscribers reported at June 30,
