Every six months RootMetrics® releases its US Mobile Network Performance report, a comprehensive look at how the top four carriers are performing. The data is based on more than 265,000 miles of drive tests and 4,200 indoor location tests conducted across all 50 states, covering 100% of the population.
Today’s report covering the first half of 2016 validates what we already knew – that Sprint continues to make strong improvement, despite being significantly outspent by the competition. In the past six months we saw notable gains in network reliability at the Metro level as we expanded our LTE coverage and increased our number of LTE Plus markets to 237. We’re proud of the progress we’re making and we clearly see the benefits of our 2.5 GHz deployment.
Consider the following 1H16 RootMetrics results:
We increased the number of network reliability awards received by 75% in the past six months, from 24 to 42 shared awards in the 125 Metro areas tested, including wins in markets such as Chicago, Houston, and Atlanta.

Nationally, we maintained our third place ranking in Overall performance, Reliability and Text.


Sprint ranks 2nd in Call performance nationally.

RootMetrics is one source of measurement that validates our improving performance. Other third-parties also tell a similar story. 
  • Sprint’s analysis of drive test data from Nielsen – covering the top 106 metropolitan markets in the U.S. – shows that Sprint’s reliability now beats T-Mobile’s and performs within 1% of AT&T and Verizon.1


  • PC Magazine’s Fastest Mobile Networks report recently noted that Sprint beat both T-Mobile and AT&T in average download speeds, and beat Verizon in reliability. Compared to last year’s PC Magazine report our national LTE Mobile Speed Index increased by 22%, and our average download speed across 30 cities improved 62%, jumping from 12.7 Mbps to 20.6 Mbps. Nationally our maximum download speed also grew a whopping 70%, increasing from 72 Mbps to 122.6 Mbps.
RootMetrics has also begun its 2H16 testing and we’re pleased to report early momentum with a tie for #1 in network reliability, call and text in Tucson, AZ, and Knoxville, TN; a tie for #1 in overall performance, reliability and speed in Colorado Springs, CO; and a tie for #1 in call in Cincinnati.

It’s great to win awards and be recognized for improvements. But at the end of the day one carrier “winning” doesn’t mean another carrier is losing. What the other carriers don’t want customers to know, is that in 2016 all networks are great, with a gap in performance that is small (and often indiscernible to most customers), but the difference in value is huge. Millions are switching to Sprint, and more are staying, as evidenced by our lowest postpaid churn rates ever. It’s clear that more and more people are realizing they don’t have to choose between a good network and one they can afford – at Sprint they can have both.
