T-Mobile boosts LTE network speeds in Dallas using MetroPCS spectrum I

Hey, North Dallas T-Mobile customer -- that speedier internet connection isn't a figment of your imagination. Just before Thanksgiving, the carrier silently got the ball rolling on its plans to unleash a faster LTE network. To achieve this upgrade, Deutsche Telekom combined its LTE spectrum with that of MetroPCS, which it acquired for $1.5 billion earlier this year. Best of all, T-Mo's improved network doesn't require a device upgrade (unlike Sprint's enhanced LTE service) -- your current one will work just fine. Unfortunately, Magenta's efforts are currently confined to select portions of northern Dallas, but it hopes to eventually roll out its faster LTE network to other top markets in the US.
