RootMetrics Report: T-Mobile Takes the Lead in Overall Mobile Performance in Boston

BELLEVUE, Wash., June 30, 2015 (GLOBE NEWSWIRE) -- T-Mobile has moved up in the mobile performance rankings to share the title of top-performing carrier in the Boston metro area with AT &T according to the latest data from RootMetrics®, the standard for independent mobile performance information.

The RootMetrics 1st Half 2015 Boston RootScore® Report marks the first time T-Mobile has won or shared the Overall RootScore Award—which includes results across data, call, and text testing—in eight rounds of RootMetrics testing in Boston. Verizon, which tied with AT &T for first place in the previous round of testing, came in third in overall performance this time. Sprint finished fourth.

In fact, T-Mobile shared first place or claimed it outright in five out of the six RootMetrics RootScore mobile performance categories for Boston. In the last testing period, T-Mobile won two top awards.

T-Mobile wasn't the only carrier with improved performance. In great news for consumers, all networks showed excellent performance and tied four ways for both the Network Reliability and Call awards. In the last testing period, Verizon won both categories outright.

With more than 335 million mobile subscriber connections in the U.S.1, mobile network performance insights and comparisons are critical elements to a positive consumer experience. RootScore® Reports provide an independent and consumer-focused assessment of mobile network performance in the 125 largest metro areas across the US, the 50 busiest US airports, and major event venues across the country, as well as at state and national levels.

The final RootMetrics Overall Performance RootScore rankings for Boston:

1 – T-Mobile (97.9)
1 – AT &T (97.8)
3 – Verizon (96.9)
4 – Sprint (95.4)

A good Overall RootScore means strong overall performance and a good consumer experience.

Network Reliability and Speed

Reliability and speed are crucial to a quality mobile experience. RootMetrics combines reliability and speed results into its Network Reliability Index, a combination of results from data, call, and text tests, and its Network Speed Index, which examines data and text results.

In the new Boston RootScore Report, all four carriers tied for first place in network reliability with outstanding results. Notably, this was the first time either Sprint or T-Mobile have ranked first in network reliability in Boston. In the previous round of testing, Verizon won this award outright. T-Mobile maintained its lead in speed, however, ranking first in network speed for the third consecutive time.
