COLUMBIA, S.C., May 6, 2013 /PRNewswire/ -- AT&T* wireless customers in
Columbia, SC, are enjoying the network ranked highest for combined/overall
voice, data and text performance by an independent mobile research and testing


Seattle-based RootMetrics® today released a wireless network performance study
for Columbia, which names AT&T in a tie as the overall RootMetrics RootScore®
Award winner for its combination of call, text and mobile Internet

The RootMetrics award is based on analysis of more than 14,800 wireless test
calls, texts and mobile Internet transmissions conducted during March, 2013.

"AT&T is tied for the highest rank in Columbia for overall network
performance, according to our research conducted in March, 2013. We tested
call, data and text performance across all networks in the Columbia area,
including over 4G LTE networks. As a result, AT&T tied for the RootScore Award
for overall performance in the area," said Bill Moore, RootMetrics' President
and CEO.

AT&T launched 4G LTE** in Columbia in November, 2012, and it plans to expand
its 4G LTE network to cover 300 million people nationwide by year-end 2014.
Even as 4G LTE expands, customers can get 4G speeds outside of 4G LTE areas
with our 4G HSPA+ technology.

"Our customers have told us they've been amazed by the speeds and quality of
our 4G LTE network, and the latest RootMetrics test backs that up," said
Laurent Therivel, AT&T's VP/GM of Mobility and Consumer Markets in the
Carolinas. "There are more reasons than ever to choose AT&T. We invested
nearly $275 million in the Columbia wireless and wireline networks from 2010
through 2012, and we'll continue investing in order to give our customers the
best possible experience."

The testing period covering Columbia, SC, released on May 6, 2013, measured
14,840 call, data, and text tests of mobile service experience by RootMetrics.
