The RootMetrics® wireless network performance study for Columbia named AT&T as the overall RootMetrics RootScore® Award winner for its combination of call, text and mobile Internet performance.

This is the second consecutive study Columbia has been ranked 1^st by RootMetrics.

"AT&T has the highest rank in Columbia for overall network performance, according to our research conducted in August 2013.

"They want service they can depend on as they travel in and around the Columbia area. We are happy to see our network investment is paying off and our customers are getting top-ranked wireless performance.
