I actually get badass 5G speeds in the middle of nowhere rural Alabama with T-Mobile, the only issue is it being a CGNAT preventing me from playing most PS3 games online.
If you're lucky enough to live near an updated and uncongested tower, then yeah.
The same thing happened for my parents in rural Utah, just with FTTH instead. Unfortunately for them, they are overcharged enough that it's probably worth it at this point to switch to 5G.
