Wifi calling on unlocked Ultra?

[indianajonze]

I can also confirm that the unlocked version of the S20 Ultra does not work with AT&T wifi calling even though spending hours on the phone with them. telling me that they have provisioned the phone to work on the network i could never get the option on the phone it self to turn it on. samsung were not helpful with the matter when asking if i could return the phone and buy the ATT version in its place.

yep same. i actually have two s20s, both pluses, one unlocked and one at&t. the at&t version happily asks to set up wifi calling (and visual voicemail) during the setup process and you're good to go within seconds. you provision your address info for 911, it changes the nav bar wifi logo to add some little stars around it and your gtg with an option in wifi settings to turn it on or off at your leisure

the unlocked version has none of this. no mention during setup, no option in settings, nothing. it simply does not exist. i also now suspect there's no VoLTE or HD voice either.

so...unlocked 5G S20: can hop from carrier to carrier at will, no bloatware
at&t locked 5G: WiFi calling, VoLTE, HD Voice, bloatware that is easily removed

buyer beware...hoping this will change when the phone is "officially" released tomorrow, but not holding my breath

VoLTE appears to work for many people unlocked on At&t, wifi calling does not.

do you have a source for that? no option for that at all for me, either called VoLTE or Calling Plus. and all calls i place instantly show up as my dear old friend H+

unlocked s20 plus on at&t. no wifi calling and no duo dialer integration. actually, to clarify, duo is an option in the individual contacts, but it's not integrated into the home screen of the dialer like the carrier models

I'm on Verizon with an unlocked S20+. VoLTE, wifi calling, HD voice, visual voicemail all work. Duo is integrated into the main dialer screen on my phone. FWIW for those also on Verizon.

The people in this thread got VoLTE working on their unlocked models on At&t.
