T-Mobile is finally ready to throw its hat into the 5G ring. The magenta carrier will launch its 5G network on June 28, in parts of six urban areas: Atlanta, Cleveland, Dallas, Las Vegas, Los Angeles, and New York. If you live in any of those places, check out TMo's coverage maps - it made one for each city. Don't expect a lot at this point, it uses mmWave technology which requires a lot of 'towers' for coverage. If you're lucky enough to spend your time in an area that will get coverage from the get-go, perhaps you'd like a 5G smartphone to take advantage of the new network....
