    Strange WiFi Calling Issue on iPad Since iOS 12-wi-fi-calling-error.jpg

    I keep having an issue with Wi-Fi Calling staying enabled on my 2017 iPad (Wi-Fi only, no Cellular). It will enable itself sometimes, then later on I will get the message above. Everything is toggled on correctly on my iPhone 8 Plus for Wi-Fi Calling and iPad (both devices running iOS 12). I contacted AT&T and they said there is no limit on devices connected to the Wi-Fi calling feature so I have no idea where this pop-up is coming from. AT&T looked at their logs and said my iPhone is okay (iPad was purchased from Apple)...no Wi-Fi Calling issues...it is running fine. Apple so far is at a lost but I am still working with a dedicated tech on this. This never happened until iOS12. Tech even had me do a complete reinstall of iOS 12 in Recovery Mode and it worked fine for for about 12 hours then started acting up again. does anyone have any insights? Thanks!!

    Go to iCloud in Settings on any of the two devices and see if there are any devices listed that are not anymore in your possession.
    Delete them.

    Maybe that helps.

    Did you purchase the iPad new, or was it used?

    Purchased as a certified refurb directly from Apple. Issue didn't exist until iOS12 was installed.

    When you set it up from recovery mode, did you set it up as new, or from a back up?

    Both ways...trust me, I have done everything conceivable, signed out then back into Facetime, you name it. Since using recovery mode on my iPhone and reinstalling iOS 12 as well as iPad issue still remains. My belief is this is related to changes in FaceTime. I'm hoping my tech contact at Apple will be able to shed more light on the issue. I have been keeping a detailed log of everything happening.

    How can an iPad have Wi-Fi Calling if it lacks the phone dialer?

    It is part of Apple’s Continuity feature.

    It is also a feature from AT&T called “NumberSync”, which allows AT&T Wi-Fi calling on your other Apple devices, such as, iOS devices and your Mac.

    I just went through this issue yesterday with AT&T and finally got it resolved. After updating my Watch series 2 to Watch OS 5, I noticed that when I turned on Wi-Fi calling from the Watch app on my phone, I got the pop-up that I had exceeded the limit of devices associated with NumberSync. The limit is 5, I have 3: my iPad, my Watch series 2 and Mac, though I had decided to remove my Mac a year or two ago.

    When I went to my phone settings on my iPhone: Settings>Phone>Wi-Fi Calling>Update Emergency Address, it showed 7 NumberSync devices. Most were duplicates with no way to delete them. I should have been able to follow directions online to remove them from my AT&T account settings, though nothing showed.

    I made a trip to my local AT&T store. They advised AT&T tech support and were baffled. I called AT&T tech support who advised me to reset my Apple Watch and set up as new. That didn’t fix it. The second tech supervisor advised it was an E911 provisioning error on Apple’s end and told me to completely log out of Apple ID and they would call right back in a minute to do a conference call with Apple tech support. They never called back. After two hours I called AT&T back and got a knowledgeable supervisor who knew what to do. The Supervisor removed NumberSync and Wi-Fi calling from my account, which cleared all devices associated with NumberSync. Then the supervisor added NumberSync and Wi-Fi calling back to my account. That resolved the issue.

    Awesome, thanks for the follow-up, and I hope that nobody else has to deal with this, but I am glad that you posted that so that somebody else might find the help that they need.

    It is an easy enough fix, though it is a mess getting the right person who understands what needs to be done. I hope this is helpful.

    AT&T performed removing NumberSync and Wi-Fi calling from my account, then added NumberSync and Wi-Fi calling back to my account. This did not work. In my calls with Apple they have admitted the error popup is generated by iOS and it does appear to be an iOS 12 problem. I have found a temporary workaround for when it happens: On my iPhone I go to Settings>Phone>Wi-Fi Calling and turn Wi-Fi Calling on this iPhone off as well as Add Wi-Fi Calling for Other Devices off, then back on again. I get the popup on my iPad asking me to enable Wi-Fi Calling and after going through the prompts all is well, even on my Apple Watch. It usually holds for several hours, sometimes more than 12, then I have to do it again. Hopefully this will be fixed in 12.1.

    Thanks for sharing. AT&T removing both features from my account, having me reboot, and then having them re add, worked for me. Problem hasn’t returned. My phone, watch and tablet works fine since. I hope there is a resolution for you and others.
