Wifi calling on Simple mobile with Moto G6

[laurelp52]

Will it switch to carrier calling automatically if it can't get a wifi signal?

It should. But since voice is unlimited, you should have the phone set to use carrier voice, with fallback to Wifi, not the other way around. If TMobile (the towers Simple Mobile uses) doesn't have solid signal wherever you need signal, perhaps it's time to think about switching carriers.
