Alaska Communications Systems Unveils Expanded Retail Location.

ANCHORAGE, Alaska -- Alaska Communications Systems Group, Inc. ("ACS") (Nasdaq:ALSK), Alaska's premier communications provider, today announced the expansion of its Dimond Center store, located at 800 Dimond Boulevard.

One of the highlights of the expanded store is the introduction of ACS' first 'Test the Best' station, an interactive demonstration center that compares ACS Mobile Internet speeds to the competition.

"This is our customers' chance to really see what 'six times faster than the competition means'," said Connie Dorman, ACS director of marketing. "We talk a lot about the speed of this service, but you don't really understand the difference until you test it yourself. 'Test the Best' gives everyone that opportunity, because we've placed ACS Mobile Internet service side by side against at&t's."

In addition to introducing 'Test the Best', to celebrate the store's expansion, ACS is also offering a special deal from now until May 18th; customers can add The Works feature pack to any individual or family wireless plan and get 50% off any phone in the store. Details are available at the Dimond Center store or online at www.acsalaska.com.
