Today OpenSignal gave us an update on how AT&T and Verizon’s networks have been faring one year after launching unlimited data plans, and there’s some T-Mobile news sprinkled in there, too.

OpenSignal reports that while AT&T and Verizon saw their LTE download speeds decrease in the months after launching unlimited plans, those speeds began to stabilize near the end of 2017. Verizon’s speeds even began to creep back up. However, AT&T and Verizon’s LTE download speeds near the end of 2017 were considerably slower than they were at the start of 2017.

Meanwhile, T-Mobile saw its LTE download speeds grow for much of 2017. T-Mo had the fastest LTE download speeds among the big four U.S. carriers at the end of 2017, according to OpenSignal, offering average LTE download speeds of around 19Mbps. To compare, Verizon’s average LTE download speed at the end of 2017 was 16Mbps, AT&T’s was around 12.5Mbps, and Sprint’s was a little below 12Mbps.

T-Mobile likes to talk about how the LTE download speeds of AT&T and Verizon fell after they began offering unlimited plans early last year, and this OpenSignal report will give T-Mo more to ammo to use against its competition. OpenSignal plans to share more of its data about U.S. networks in a new State of Mobile Network: USA report soon, so stay tuned for that.
