The return of unlimited data plans from the nation’s big four wireless carriers hasn’t hurt network performance, according to the latest report from RootMetrics.
For the first half of 2017, the testing firm reports that all four major wireless carriers improved their median network speeds in at least 20 markets. AT&T improved in 51 metro markets, while T-Mobile saw improvement in 73 markets. Sprint also continued to see big improvements in performance. The companies all improved the percentage of markets that are also able to get more than 20 megabits per second downloads.
The increased network speeds in more markets comes at a time when competition in the wireless market is heating up. Each of the major carriers have reintroduced unlimited data plans as a way to steal customers from competitors. In January, T-Mobile went all-in on its unlimited option, removing all other options. AT&T and Sprint also touted their own all-you-can-eat options. Then in February, Verizon quietly brought back its own unlimited plan for the first time in seven years.
“The fact that all carriers improved their median download speeds in 20 markets or more suggests that regardless of what is happening with data plans, the carriers are taking steps to mitigate any negatives from increased demand just not seeing a big decline or any decline really,” said Annette Hamilton, Director at Root Metrics.
For the eighth time in a row, Verizon Wireless ranked No. 1 nationally in overall performance, reliability, speed, data, and calls. AT&T took second place, while Sprint was third and T-Mobile ranked fourth.
But T-Mobile claims that the move to unlimited data has taken a toll on AT&T’s and Verizon’s networks resulting in slower download speeds for consumers. In a blog post last week, T-Mobile CTO Neville Ray claimed it has the fastest wireless network in the US.
“The real news is how dramatically both AT&T and Verizon’s networks have caved since making unlimited available to their customers—all while T-Mobile’s network has continued to soar,” he said.
Meanwhile, Ray downplayed the results from RootMetrics and insinuated that Verizon is paying RootMetrics to come up with these results.
“Unbiased scientific studies tell us loud and clear that Verizon’s network is struggling with unlimited and T-Mobile has caught up,” Ray said in a statement provided to CNET. “That’s based on millions of actual customer experiences, not consultants funded by Verizon. Color me surprised that a Verizon-sponsored report claims they’re on top.”
RootMetrics’ Hamilton wouldn’t say whether Verizon is a current customer, but she did say that at one time or another all four major carriers have been RootMetrics customers. She also explained that data T-Mobile uses to base its claims is flawed.
T-Mobile’s data on network performance comes from crowd-sourced apps such as Ookla’s SpeedTest. Ray of T-Mobile argues that these apps give a more accurate picture of how the network is performing in the real world, because it aggregates testing information from customers who use the app to test their mobile connections. But Hamilton said crowdsourced testing apps don’t offer a fair comparison because the testing parameters aren’t uniform. There’s no way to control for the location or time of day the tests were conducted.
RootMetrics conducts its own testing and it doesn’t use crowd-sourced data. Instead of taking data from a testing app that consumers use to check their network speed, RootMetrics tests the network itself. It has complete control over the testing environment. Hamilton said this offers a more accurate view of network performance because it has tried to control the conditions of the test as much as possible.
“You can make statistics say whatever you want,” she said. “In this case, T-Mobile is not choosing the most scientifically rigorous data.”
Still, Hamilton doesn’t deny that T-Mobile has made major improvements in its performance. In fact, RootMetrics recorded the fastest download speeds in the country from T-Mobile. According to RootMetrics’ data, T-Mobile clocked download speeds of 48.9 Mbps in Lansing Michigan. It’s slowest market was in Stockton, California where it recorded speeds of only 5.8 Mbps.
Sprint also “showed strong improvements to the number of markets in which it delivered median download speeds of 20 Mbps or faster,” according to the report. Its fastest median download speed of 33.9 Mbps was recorded by RootMetrics in Atlanta, GA.
