Maybe it really is?
AT&T's wireless network was named the fastest in the US, it announced Wednesday, based on an analysis of speeds over the first quarter of 2019 by Ookla's. It noted that AT&T's speeds improved by more than 15% during that period, while the other carriers plateaued.
AT&T's speeds jumped from 34.3 megabytes per second (MBPS) to 40.7 MBPS, according to the data it presented. By comparison, T-Mobile hit 35.4 MBPS, Sprint reached 34.9 MBPS and Verizon was at 33.3 MBPS.

"We are thrilled Ookla has confirmed that we are the fastest wireless network nationwide," said Andre Fuetsch, president of AT&T Labs and chief technology officer.

Responding to results from Speedtest, Verizon asserted that its wireless network is the fastest and most reliable.
"The evidence is overwhelming that the Verizon wireless network is best, fastest and most reliable," said spokesperson Howie Waterman in an emailed statement. "We focus on deploying the best technologies for our customers, at scale."
T-Mobile made a similar claim, noting that that people use their phones for upload as well as download.
"When you look at the overall customer experience, there's only one fastest LTE network: T-Mobile," said Neville Ray, its chief technology officer. "We've led the industry on LTE speed for five years (20 straight quarters), all without lying to customers or pretending LTE is 5G."
