So annoyed... after working to get wifi calling working and figured out with rogers I just upgraded to 9.2 ios only to find same problems as I initially had. The wifi calling can't be enabled until I contact carrier. I contacted technical support and he couldn't figure it out and has escalated the issue. I have an Iphone 6s and it seems that I spend more time trying to get wifi calling to work properly than I do using it. Seems that this is feature they shouldn't be advertising yet. So now I can't enable wifi calling... again and the carrier which I'm directed to contact doesn't have a solution. Man I am so tired of this.
I'm having the same issue. Wifi calling was working fine under iOS 9.1 and now with 9.2 I get the contact carrier message. I've tried rebooting, and resetting network settings. No luck, my wifi calling is no longer working under 9.2 with the latest carrier file.
Same issue here, my wifi calling is no longer working under 9.2 with the latest carrier file updates. iPhone 6S purchased from Apple. Another 6S+ also purchased through Apple works completely fine. Rogers escalated the issue to Level 2 Tech Support a few days ago but still no resolution!?!
I purchased my iPhone 6 unlocked directly from Apple, and I can confirm Wi-Fi calling works for me. I'm running iOS 9.2 with carrier "Rogers 23.1".
@RogersDarrell, you may want to edit your post as you have clearly been given erroneous information.
To be fair to Rogers, it is still possible that it's an iOS bug that is causing your issue, which is really out of their control. Have you tried a different Wi-Fi network? You might also try going to Settings > General > Reset and tap "Reset Network Settings" (but be warned, you will need to reconnect to any Wi-Fi networks you use after doing that).
