The US wireless industry is very competitive and you have to admit that T-Mobile has been leading the way to change the way business is run for the benefit of customers. However, when it comes to nationwide network performance, it's pretty clear that Verizon leads with AT&T following close behind.
RootMetrics performed 6.1 million tests, drove 237,506 miles, tested 7,323 indoor locations, and claims that 100 percent of the population was covered. They used un-modified, carrier supplied Android smartphones to conduct the tests around the country.
Verizon earned first place RootScore Awards for overall performance, network reliability, network speed, data performance, and call performance. AT&T won the award for text performance, but was also in second for all the other awards that Verizon won. T-Mobile finished last in four of six areas and third in network speed and data performance. Sprint beat out T-Mobile in the other four categories.
The RootMetrics report breaks the results down into finer detail, but even in the metro area report where T-Mobile focuses its efforts Verizon and AT&T each won at least twice as many awards. T-Mobile did beat Verizon in metro texting, but AT&T easily captured this category.
The full report has a vast amount of data and results, providing details for each carrier. Test results include blocked calls, dropped calls, data connection reliability, and more.
