Verizon still on top and T-Mobile still struggling, according to RootMetrics
July 31, 2025
If you’ve ever readaRootMetricsreportbefore, you are used to seeing one company dominate pretty much every category:Verizon. Whether the test is on coverage, speed, or call reliability, Verizon tends to own the other three major U.S. carriers by a longshot.
As such,the latestRootMetricsreportfor the second half of 2017 is not all that surprising. The overall national score for Verizon’s service was 95, whileAT&Tcame in second at 92.8.Sprintheld onto third place with 87.8, andT-Mobilecame in last with 86.8.
RootMetricsobtains its data privately by using unmodified Android smartphones on a variety of networks, in a variety of places, at varying times. It samples areas in all 50 states and compiles the data into a national score as well as a per-state score, so wireless consumers can get an unbiased look at how each carrier’s service will work for them.
T-Mobile, never happy with its consistent fourth place billing, is often publicly critical ofRootMetrics’methodology. The company claims that the dataRootMetricscollects comes from “paid consultants” and that the only true way to establish an unbiased coverage dataset is to use crowdsourcing.OpenSignal, the company T-Mobile offers as an alternative data source, has T-Mobile neck-and-neck with Verizon when it comes to speed and a close race when it comes to 4G LTE availability.
Predictably, it wasn’t long before T-Mobile made a statement about the latestRootMetricsreport. Here’s what CTO of T-Mobile Neville Ray had to say:
