For instance, 4G occupied the frequency bands up to 20 MHz. In the case of 5G, it will likely sit on the frequency band up to 6GHz.

It’s unlimited, but after a certain point you get knocked down the priority list (I think it’s 21GB per month, not 100% sure). That means if you are in an area that’s not congested, you keep on as if nothing happened, but if you are in a congested area with lots of people using the signal, you get pushed to the back…

I’m very happy with my unlimited on T-Mobile. Not to mention itsit’s faster than even Verizon
