Verizon led in individual categories such as Network Reliability, Network Speed, Data Performance, Call Performance and tied AT&T in Text Performance. AT&T finished second in all categories except Text, in which it finished in a tie with Verizon, and in Call Performance where it finished third. Sprint finished second in that category.
Obviously not all of the carriers are going to be pleased with the results, and some might have reason to feel that the scores are not totally indicative of their performance. For example, because RootMetrics does not track VoLTE calls, 50% of T-Mobile's performance was not measured for the summary. On the other hand, RootMetrics did test the carrier's pipeline using a 700MHz enabled handset, compatible with T-Mobile's Extended Range LTE service.
The fastest download speed measured during the testing was the 44.9 Mbps achieved by the T-Mobile network in Lansing, Michigan. The slowest was Sprint's .7Mbps in El Paso, Texas.
