MILLICOM INSTITUTES INTERNATIONAL ARBITRATION PROCEEDINGS REGARDING SENEGAL
LICENSE

New York and Stockholm - 11 November, 2008 - Millicom International Cellular
S.A. (Millicom) (Nasdaq Stock Market: MICC and Stockholmsbörsen: MIC), the
global telecommunications company, today announces that its subsidiaries
Millicom International Operations, B.V. (MIO B.V.) and Sentel GSM S.A (Sentel),
have instituted arbitration proceedings with the International Center for the
Settlement of Investment Disputes (ICSID) against the Republic of Senegal under
provisions of Sentel's license and international law.  MIO B.V. and Sentel seek
compensation for the purported expropriation of the Senegal license and monetary
damages for breach of the license.

Also today, the Republic of Senegal instituted court proceedings in Senegal
against Millicom and Sentel.  In that proceeding, the government alleges that it
has cancelled Sentel's license and seeks damages against Sentel and Millicom
under various theories. Millicom believes that the action filed by the Republic
of Senegal is baseless and ignores the agreement between Sentel and the Republic
of Senegal to submit any dispute concerning the license to an international
arbitration forum.

Millicom's commitment to its business in Senegal remains strong and MIO B.V. and
Sentel intend to vigorously pursue all available remedies in the matter before
the international arbitration forum.
