Hi all. On my six S plus, I enabled wifi calling as our cell coverage isn't great. Yesterday out of nowhere, I noticed my bars said LTE. Thinking nothing, I reconected. This morning I had a good chat with a friend. Just a few minutes ago, my Mac told me, something along the lines of wifi calling can't be enabled on this account, contact carrier. I just updated to IOS 10.3 and would really like to not have to call if I don't have too. I reset network settings, I also reset the phone with home and power. I didn't turn it off and back on as that did the same thing, even turned off then on, wifi calling. Any help would be great. thanks. btw, I mean the IOS 30.3.2 or whatever the mini update was.
