BELLEVUE, Wash., Oct. 6, 2016 (GLOBE NEWSWIRE) -- RootMetrics®, the global standard for independent mobile performance information, is out with its latest RootScore Report for Denver revealing interesting changes across the network performance rankings.

Sprint is a close competitor in these latest rankings from RootMetrics, an IHS Markit (Nasdaq: INFO) company. The carrier, which held three awards during the previous testing period, now shares awards in five of the six categories tested.

"Delving into the results from our latest testing in Denver, we're seeing some interesting changes in the rankings," said Annette Hamilton, RootMetrics director. "With Verizon and Sprint jumping up our mobile performance rankings, as well as notable data speed improvements across the carriers, mobile consumers in Denver are benefiting from the continued competition."
