Hey, sorry, I’m not in the US so I wasn’t sure what it’s called there. It’s very unlikely Cell Provider wifi calling will work.This is for when you’re in the middle of nowhere with wifi access and want to text/call as you would in service. I believe this needs a special phone from the provider itself to work and even then it’s not all phones.
If, for example, you have a voip provider, Google voice, skype, matrix, tin cans, etc you will (should?) be able to use these over wifi as you have been all along. Just download a linux app, set it up, and use it.
