European Phone, American SIM-card

I have both a TMobile phone plan in Europe and a Prepaid TMobile plan here in the U.S. 
I was wondering, when I get a new phone on my European plan, would I be able to insert my U.S. SIM-card and have a decent connection? I’m looking at either an Iphone SE, 11 or 12 Mini and would be primarily use it in the Pittsburgh, PA area. I would be open to other Iphones as well if this changes the performance. Thank you!

As long as the phone is SIM unlocked, it will work fine on T-Mobile USA’s network.

iPhones these days are very carrier agnostic. You might even be able to use an eSIM with your physical SIMand have both SIMs active at the same time.
