i bought s20 ultra from bestbuy, unlocked version, and im on ATT. also, i switched from iphoneX where visual voicemail and wifi calling exist (note: my iphone x was from tmobile but unlocked, and switched networks).
visual voicemail is not working, and there's no option for me for wifi calling either.
i bought the S20 Ultra unlocked because of the article I saw on PC Mag. Guess what? Wifi calling did not work on ATT network. I switched the ATT sim with my other sim from Verizon , Voila, Wifi calling showed up and so did Voice over LTE. ATT continues to block WIFI calling for the unlocked Samsung.
@usergWhrLrg2G7 AT&T is known to be a late implementation. Heard from some sources that AT&T is currently working on allowing wifi-calling by end of 2020 on unlocked devices. Sooner or later we will receive an update to enable that.
Did anyone ever get wifi calling to work? I was just on the phone with att and was told that wifi calling will work on their post paid account. Not the prepaid. I saved the entire chat just in case it doesn't. So is there a way to get the wifi calling option to even show up? My phone was originally from Verizon, should I cancel my att order and just go with Verizon or will wifi calling work when I get my new sim card? Any help would be greatly appreciated. Thank you
i have an ATT prepaid, and my wifi calling was functioning on my iphone X, also my visual voicemail. now that i switched to s20 ultra, neither of these features work now. im very sad.
