Despite a recent attempt at turning things around, Sprint doesn't seem to be doing well. Of the four major carriers in the United States, Sprint was rated the lowest in a new report released by Consumer Reports.

According to the Consumer Reports study, which surveyed over 60,000 ConsumerReports.org subscribers, found that Sprint still lagged behind in many key areas. The third-largest carrier seems to be losing momentum thanks to its call quality and network footprint/speed.

"The biggest black eye of our survey is reserved for Sprint, which ranks dead last with a very poor score for value, a poor score on data service, and middling results for voice and text," writes Consumer Reports' Glenne Derene.

"Overall, Verizon, T-Mobile, and AT&T are rather closely grouped with ratings of 69, 69, and 66 respectively. Sprint actually underperforms substantively with a rating of 59, the lowest rating according to Consumer Reports. In all 10 ranked categories, Sprint finished below average except for three." — The Motley Fool.

A Sprint spokesperson responded to Consumer Reports, saying that the company has enacted new strategies that involve "dramatic changes in the two areas that matter most to customers-price and network."

Sprint also ranked last out of the four national U.S. networks a recent RootMetric study evaluating overall performance.

Sprint brought in Bolivian billionaire and founder of Brightstar Corp. Marcelo Claure in August to replace CEO Dan Hesse and has since rolled out a series of aggressive new pricing plans aimed to making it more appealing to customers. Plans involve family data sharing plans and an iPhone-specific deal that allows for upgrading every year.

Verizon, meanwhile, ranked high when it came to voice and texting but lacked perceived value, something T-Mobile scores well in thanks to its new "Uncarrier" strategy that has shifted the industry away from contracts and long waits between upgrades.

"The choices Verizon offers on the nation's largest and most reliable 4G LTE network go well beyond price. We'll continue to work to demonstrate value by providing excellent customer experiences," a Verizon representative told Consumer Reports.

Small and relatively unknown carrier Ting ranked the highest, although it does not have nearly the same coverage area as the four big ones.

"What we do is actually sort of obvious," Ting CEO Elliot Noss said. "We offer fair, honest pricing that doesn't penalize customers for using too much or too little. Our customers seem to appreciate it and we certainly appreciate this recognition from them."
