DENVER — AT&T was named the best mobile carrier in Colorado, according to a historic statewide report from an independent mobile network researcher.
Calling the study “the most comprehensive mobile performance study ever undertaken,” RootMetrics reported collecting 4.6 million test samples from across the country. The surveyor indicated that 6,300 locations were tested and that 218,000 miles were driven to collect the data and compile the final scores.
The surveyors also claim this is the first report in mobile data history to offer state-by-state findings. In Colorado, RootMetrics reporting driving 3,646 miles, checking the quality of each carrier’s network in 79 different locations throughout the state.
After all was said and done, Colorado was one of just three states where AT&T won outright for “Overall Performance,” logging a score of 77.5 to Verizon’s 70.3. Verizon won outright in 36 states, and AT&T tied with Verizon in 11 states.
T-Mobile and Sprint were a distant third and fourth in most states, including Colorado, where T-Mobile came in third with a score of 59.7, and Sprint was fourth with a score of 55.2.
It’s safe to say the the survey data did not please outspoken T-Mobile CEO John Legere, who took to Twitter to dispute the findings.

At the heart of Legere’s disapproval appears to be T-Mobile’s “Ucarrier” marketing campaign, which helped the wireless carrier gain momentum as 2013 went on. The company reportedly gained 4.4 million subscribers over the course of the year.
Though AT&T did win the battle in overall performance in Colorado, it did not run a clean sweep through all of RootMetrics’ categories. For instance, Verizon just edged out AT&T in terms of “Speed Index,” with a final score of 83.4 to 82.3.
Verizon was also named the winner for “Overall Performance” in Colorado’s two biggest cities, Denver and Colorado Springs.
However, when it came to RootMetrics’ other categories in Colorado, AT&T was on top, posting the winning scores for “Reliability Index,” “Data Performance,” “Call Performance” and “Text Performance.”
