Mobile performance in the US part 1

To show how the major US carriers fared in the second half of 2018 across all the spaces in which you use your smartphone, we’re offering our semi-annual three-part series of complementary special reports on mobile performance in the US. These reports can be used together to see how the carriers performed across the entire US, within each of the 50 states, and across the 125 most populated metropolitan markets in the country. To earn our United States RootScore Awards, a network needs to offer outstanding performance across all of the different spaces where consumers use their smartphones, from cities and towns of all sizes to highways, rural areas, and all the places in between. Key Takeaways:

• AT&T remained a strong number-two performer at the national level, again ranking second in five out of six performance categories and earning a share of the Text RootScore Award.
• Sprint finished third or fourth in each category for the second straight test period, but the carrier’s ranking in the network reliability category declined in this test period.
• T-Mobile's ranking in the network reliability category improved since our last test period. The carrier’s rankings in our other five performance categories remained identical to those from the first half of 2018.
• Verizon shined on the national stage once again, winning or sharing the United States RootScore Award in all six categories.
