All four of the national carriers will find something to like in RootMetrics’ most recent national, state and metro-level testing. AT&T was recognized for improved network speeds, Sprint for a respectable and consistent showing, and T-Mobile US for bolstering network reliability and call performance—but Verizon still continued to dominate in overall performance.
RootMetrics’ most recent U.S. State of the Mobile Union report for the second half of 2019 is based on more than 3.85 million tests performed, with drive testing of more than 225,000 miles and indoor testing at more than 7,700 locations around the country.
