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.

The first half of 2016 marked another period of large-scale change to the US mobile landscape for both carriers and consumers alike. To give you an up-to-date and comprehensive look at how the networks performed in the face of this dynamic mobile landscape, our testing looked at performance across the breadth of the United States itself, in each of the 50 states, and within the 125 most populous metro areas across the country. Our latest data shows important changes to the mobile race as the carriers have continued to add capacity, expand their LTE footprints, and launch new technologies to improve your mobile experience.

AT&T remains a strong number-two performer behind Verizon at the national level. AT&T finished second to Verizon in five out of six categories at the national level, including the holistic areas of overall performance, network reliability, network speed, and data performance. The only area in which AT&T didn’t rank second behind Verizon was in the Call RootScore category; Sprint again narrowly edged past AT&T to finish second.
