Independent mobile analytics firm RootMetrics® awards top spot to AT&T in recent wireless network performance test

COLUMBIA, SC — A newly released report shows AT&T* wireless customers in Columbia are enjoying the highest ranked local network. An independent mobile research and testing organization today named AT&T’s wireless network for top honors. Seattle-based RootMetrics ranked AT&T highest for overall – call, data and text – network performance in Columbia.

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.** The RootMetrics award is based on analysis of 19,072 wireless test calls, texts and data transmissions conducted during June, 2015.

“AT&T was ranked highest in our June, 2015 tests of overall network performance in the Columbia area. Our overall RootScore Award looks at data, call and text performance across all data network technologies, including 4G LTE. We look at performance from the consumer’s point of view, and AT&T offered a very strong overall performance for those in Columbia during our tests,” said Bill Moore, president and CEO of RootMetrics.

AT&T launched 4G LTE** in Columbia in September 2012.

“Our customers depend on their wireless service to help manage their busy lives,” said Pamela Lackey, President of AT&T for South Carolina. “They want service they can depend on as they travel in the Columbia area. We are happy to see our network investment is paying off and our customers are getting top-ranked wireless performance.”
