Question about 4G and Verizon

[texmaster]

I'm in Dallas which I think has pretty good 4 G coverage but I've got a kind of a weird question. So my company has multiple locations and one location is in a tall builing 18 floors up. Verizon gets NOTHING ZERO coverage. AT&T has a rockin signal however. Would I have a better chance at getting a signal if I had a 4 G phone from Verizon?

Maybe. Depends how the antenna is set up.
