If you have a device with model ending in U1U factory unlocked from Samsung or these newer models ending in U1 you can flash whatever carrier firmware you want on to the device (granted it's a U.S. carrier) and use it.

It's not hard but one wrong move and you could end up with a bricked device which is fixable it just has to be flashed correctly. The wifi calling you're looking for would be on said firmware. Wifi calling isn't a hardware function so flashing would give you the wifi calling you want.
