T-Mobile's 600MHz network will be ready for testing within the next couple of months.
After being granted the necessary spectrum licenses by the FCC on Wednesday, T-Mobile says it'll be ready for “deployment activities” this summer. The carrier spent $8 billion on the spectrum to build a network that'll become what everyone considers a “5G network” in the future. What it'll do in the short-term is bolster existing LTE coverage and increase capacity.
With customers flocking to T-Mobile at a still-impressive rate, its network needs to be prepared to hold a large number of devices simultaneously.

Devices compatible with the 600MHz network are expected debut later this year, and it's possible we see the Samsung Galaxy Note 8 as the first. T-Mobile and Samsung typically come together to give high-end Galaxy devices special capabilities. The Galaxy S8, at least in a controlled laboratory, was able to achieve gigabit-level LTE speeds on Team Magenta's network. Nothing tells us the Galaxy Note 8 won't be the first device compatible with the new spectrum.
Specifics regarding the deployment's locations and timing aren't known, but we'll share them with you when T-Mobile makes any additional details available to us.
