MIC Subscriber Review


BERTRANGE, Luxembourg, March 24, 2004 (PRIMEZONE) -- Millicom International Cellular S.A. (Nasdaq:MICC) ("MIC"), the global telecommunications investor, announces the completion of a review of its subscriber base. This review was undertaken to ensure that MIC was consistent in the way it accounted for subscribers on a global basis, so tightening MIC's strict subscriber definition. The effect of the review is that some 243,000 subscribers have been churned out bringing the total subscriber number to 5,748,508 and the proportonial subscribers number to 4,011,465 today, still slightly ahead of the year end 2003 reported subscriber numbers.

This review has minimal revenue impact and MIC's revenue growth for the first quarter of 2004 is expected to be higher than the revenue growth for the fourth quarter of 2003. The results will be reported on April 20.

The largest impact came from the regulatory authority in Paraguay introducing a new ruling on 15th November 2003 that instructs operators to remind customers that leaving a voicemail has a cost to the caller. As a result, in March 2004 MIC has seen an increasingly significant churn from low revenue generating subscribers. MIC anticipates the subscriber base in Paraguay being reduced by approximately 150,000 and this will result in a revenue loss of approximately $200,000 per month.

Following these adjustments in Paraguay MIC undertook a review for all other markets to ensure compliance with the stricter definition used for subscriber reporting, leading to another 93,000 subscribers being churned. This subsequent review will not impact revenues.
