I don't think so, none of the previous models did. I have an unlocked Note 10+ on AT&T and there is no wi-fi calling.

"I've also heard that the unlocked unit will support voice-over-LTE and Wi-Fi calling on all carriers. AT&T, especially, tends to be testy about allowing those features on unlocked phones, citing software compatibilities. But the carrier says you should be good to go with this one."

Cool, I guess I will test it when I get mine. Just to be clear, Note10 and S10 technically support it too, but it is AT&T that choose not to allow it. No idea why.

Well the Carrier (ATT) Lied .  They told me that it was a feature shut off and not supported by them because of the phones (newness) Mine is unlocked too i'd like to know if the company phones have it.  Meanwhile (during the virus ) I'm gonna have to make calls from my Garage since I live in a faraday cage for a house. They say it could come on  anytime,  but i've only got 29 days to return this phone.  I guess I can go to TMOBILE

@UserinaCAVE If you can't wait you can flash the rom to AT&T to have wifi calling on.

@userceCMC3weqT I was able to test this out at the unpacked VoLTE did work on AT&T for unlocked, however, I didnt see wifi calling option but since it is VoLTE certified on at&t you can flash AT&T firmware and wifi calling should work!20200223_233305.jpg

Yeah, I went with the AT&T model cause I didn't want to lose any of the carrier features.

The first 24hrs with my S20 Ultra and I can confirm Wifi Calling doesn't even show up. I have a case open with AT&T to hopefully resolve the issue, but more than likely I will need to exchange the phone. The Samsung chat and phone support say that AT&T is blocking.
