How do you get band 12 from T-Mobile on a Lumia 950 XL?

I have a Lumia 950 XL that gets really poor signal in places that I used to get fantastic signal with my old phone, an Alcatel OneTouch Fierce XL.

After doing a lot of research and tech support, the whole shebang, I used the Field Test app and singled out band 12 as the culprit. It's supposed to help penetrate buildings and is what gives my area great coverage. For some reason though, my 950 isn't able to connect to it. I had another post where people were saying they had great coverage on the 950, better than their old phones even.

Does anybody know how to get band 12 to work? It's pretty much the only thing I can think of that will get me my signal back full-strength.
