    Yesterday, my WiFi calling just stopped working. I have Sprint and WiFi calling has worked perfectly through two phones now until yesterday.

    Details: We have 4 iphones on the Network, 3 still work for WiFi calling.
    WiFi calling no longer works at home or work for this phone.
    WiFi calling is turned on in settings (it just behaves like it would with an unstable WiFi signal, which is not the case).
    I can still make WiFi calls using my iPad and MacBook Air through my account.
    I have already power cycled the router, hard reset the phone, turned WiFi calling off, then back on, and performed a network settings reset. Still no WiFi calling.

    Any other ideas?

    Is the iPhone in question a new phone? Did it work previously on the same phone?

    Not a new phone. It has been working on this phone solidly from May 2016 until yesterday.

    I'm wondering if maybe the signal is now good enough to not trigger wifi calling? What happens if you turn on airplane mode and leave wifi enabled?

    I am also having this same issue with my iPhone 6 that was recently upgraded to 11.2. Most certainly not a WiFi signal strength issue. Along with the OP it was working without any issue until yesterday. Have tried resetting, disabling and re-enabling the feature all with no luck.

    I solved this by downgrading to 11.1.2 by following the instructions on this video: Definitely an issue with 11.2

    Well, I don’t know what happened but it started working again this morning. I waited until now to post in case it was momentary, but it has been working all day now. Weird.

    What happens if you turn on airplane mode and leave WiFi enabled? Does WiFi calling turn back on?

    Have you tried just logging out of your WiFi, from your iPhone, then back in??

    Yep. I also reset network settings. Still no luck.

    Latest iOS update came with a carrier settings update, and that has fixed the issue.

    Awesome. Must have been something carrier specific.
