Wireless Carriers Expand Distribution to Give Customers More
                   Options for Wireless Service

CHICAGO and LITTLE ROCK, Ark., April 30, 2012 (GLOBE NEWSWIRE) -- U.S.
Cellular (NYSE:USM) and Alltel Wireless have joined together to begin
offering U Prepaid, a no contract wireless service, in select Walmart
Stores, Inc. (NYSE:WMT) in local communities across 18 states beginning
in May. The alliance, the first of its kind in the industry, offers
customers flexible payment options without signing a contract.

"Teaming with Alltel to gain distribution in Walmart gives us another
opportunity to be where our customers want to shop and to offer more
customers a prepaid service that helps them control their monthly
budgets," said Carter S. Elenz, executive vice president of sales and
customer service for U.S. Cellular. "U Prepaid customers with U.S.
Cellular will be backed by our high-speed network, which has the
highest call quality and network satisfaction of any national carrier."

The new alliance provides Walmart customers simplified,
easy-to-understand service plan choices. Depending on where customers
live, the U Prepaid service will run on either U.S. Cellular's
high-speed national network or Alltel's advanced coast-to-coast
network.

"Alltel is proud to bring the strength and equity of our U Prepaid
brand to U.S. Cellular to create this unique alliance," said Lesa
Handly, chief marketing officer for Alltel Wireless. "Together, we can
leverage our position as the "local" wireless carrier offering a
hometown alternative in the communities we serve."

Customers will be able to select one of four U Prepaid devices that
best meets their personal needs. The Android-powered Samsung Repp is a
touchscreen smartphone for customers who want to stay productive while
on the go. The LG Attune/LG Exchange and LG Saber make staying
connected to friends and family easy with full QWERTY keyboards, and
the Samsung Chrono provides the features and functionality for
customers who prefer to use their phone for calling and texting.

Customers will be able to choose from a variety of value-packed plans
to match how they use their phones. There are multiple data options and
plans that include unlimited talk and texting. All of the plans are
nationwide with no roaming charges.
