Additionally, T-Mobile is quick to say that compared to Verizon and AT&T, it made the right choice when it came to the early decision of mmWave vs. All we need to know is, the good 5G is now coast to coast. We assume its upgrading towers with new hardware and flipping switches and turning on spectrum, but a nice little breakdown from T-Mobile would be appreciated. Unfortunately, the carrier doesn’t really provide details with how this rollout works. The carrier first said that 5G UC was working towards this sort of availability late last year, so with the goal already being met, that seems impressive. T-Mobile and its “good 5G,” which is what we call its Ultra Capacity 5G network, is months of ahead of schedule and now covering 300 million people.
