LITTLE ROCK, Arkansas, Dec. 5, 2006

Alltel, America's largest wireless network, today announced that the Samsung SCH-u520 will be available exclusively at Alltel retail stores and at shopalltel.com beginning Dec. 7. The phone, designed to provide easy access to a wide range of entertainment features, is the first phone to support Alltel's new Axcess Mobile Guide service. The service allows customers to hear voice turn-by-turn directions, view maps, find locations, plan trips and more.

The Samsung SCH-u520 allows users to watch TV, listen to the radio, and access podcasts, all in high-quality stereo. The phone has a 1.3 megapixel camera, video capture and playback, and a high resolution display. It is the first Alltel phone to support A2DP Bluetooth profile, which allows customers to connect to a stereo Bluetooth headset and stream their .mp3 music through the stereo headset.

Alltel's Axcess Mobile Guide navigation service, powered by Networks In Motion, the award-winning wireless navigation and location-based services (LBS) company, will provide turn-by-turn voice directions to any destination. Customers can also view maps and search for locations such as landmarks, restaurants and ATMs. Axcess Mobile Guide is available for a $9.99 monthly subscription or a $2.99 daily pass (airtime not included).
