Business Editors

WALL, N.J.--(BUSINESS WIRE)--Dec. 5, 2001

Centennial Communications Corp. (NASDAQ: CYCL) today announced that it has brought high-tech mobile communications to Jamaica with the launch of its digital wireless service on November 29th.

The wireless service uses the latest digital technology called CDMA (Code Division Multiple Access), providing voice quality comparable to fixed line telephones. Centennial expects to offer its Jamaican customers 3G phones next year, which will enable Jamaicans to access the internet at faster speeds than currently available over traditional phone lines.

With the launch of service in Jamaica, Centennial enhances its Caribbean-wide CDMA wireless network which currently provides digital service in Puerto Rico, the Dominican Republic and the U.S. Virgin Islands, an area covering over 15 million people.

"We are truly excited about our recent launch in Jamaica, a market we believe is starved for more competition and improved services in telecommunications," said Carlos Bofill, Chief Executive Officer of Centennial's Caribbean operations. "We have the widest wireless coverage of any carrier in the Caribbean, a region we believe is significantly underserved. This coverage is bolstered by our common technology platform, CDMA, throughout the region, which facilitates roaming and our extensive terrestrial and undersea fiber-optic broadband network throughout the Caribbean."

Centennial Digital Jamaica is owned 51% by Centennial and 49% by Oceanic Digital Communications, Inc.

Centennial is one of the largest independent wireless telecommunications service providers in the United States and the Caribbean with approximately 17.5 million Net Pops and 803,200 wireless subscribers. Centennial's U.S. operations have approximately 6.0 million Net Pops in small cities and rural areas. Centennial's Caribbean integrated communications operation owns and operates wireless licenses for 11.4 million Net Pops in Puerto Rico, the Dominican Republic, Jamaica and the U.S. Virgin Islands, and provides voice, data, video and Internet services on broadband networks in the region. Welsh, Carson, Anderson & Stowe and an affiliate of The Blackstone Group are controlling shareholders of Centennial.
