ANCHORAGE, Alaska -- Alaska Communications Systems Group, Inc. ("ACS") (NASDAQ:ALSK) today announced it is expanding its telecommunications services on the island of Kodiak.

For years, ACS has served the island's residents with local, long distance, and dial-up Internet service. Now it is expanding service offerings to include wireless mobile voice and data services as well as high-speed Internet connections with its digital subscriber lines (DSL), in the most populated areas of the island.

The CDMA wireless network offers enhanced voice and data capabilities including the best voice quality, fastest data speeds, and greatest security. Mobile wireless data services will be available on cell phones, PocketPCs and aircards that work in laptop computers, providing mobile Internet connectivity at peak speeds that are multiples of dial-up.

The DSL services will enable Kodiak residents to experience high-speed Internet at the most competitive rates and speeds ever offered to residents on the island. The ACS DSL bundles include the following components: local phone service, 100 minutes of monthly long distance, voice features, and Internet speeds of 128/64Kbps for $59 per month or 256/128Kbps for $79 per month.

"Kodiak is one the state's most densely populated areas. This expansion will provide critical wireless and high-speed Internet access in an area that sits at the cross roads of the most productive fishing grounds in the world and houses one of the nation's launch facilities that promotes aerospace-related economic growth," said Liane Pelletier, ACS president and chief executive officer. "This expansion demonstrates our commitment to meet the needs of residents and businesses on the island."
