cannot turn on iphone cellular calls error

This solution worked completely for me. I couldn't use the cell calls at all. Creating the temporary user fixed it completely!!! Thanks!

Good to read the issues arising from iOS8 are being resolved but I do have one important question to ask and answers from EVERYONE are sought. How much are unable to use the iPhone Cellular Calls on the iPhone itself when only the cell number is selected? For this same cohort, who is getting the 'iCloud and Apple ID must be the same error message...? Even though in most cases they already probably are the same.

I am annoyed that in order for this feature to work, I must select the Apple ID email address in addition to my cell number for FaceTime calls. I think this is a bug that Apple aren't admitting just yet.

Many thanks,

Vishal, you are correct. I was unable to duplicate the results I achieved before, but this time I was a little more analytical in my approach, so it is possible that I drew some faulty conclusions before. Here are my findings:

With my iCloud address unchecked on both devices, FaceTime (on the iMac) does not recognize an incoming call nor can I place an outgoing call.

With my iCloud address unchecked on the iPhone, but checked on the iMac, FaceTime on the iMac does not recognize an incoming call nor can I place an outgoing call.

With my iCloud address checked on the iPhone but unchecked on the iMac, FaceTime on the iMac will both recognize incoming calls and place outgoing calls. I believe this must be the condition in which I was successful when I checked this before.

And of course with my iCloud address checked on both devices, FaceTime on the iMac will both recognize incoming calls and place outgoing calls, just as expected.

It appears, then, that it is the iPhone that is controlling functionality, as I was successful in the tests with both conditions (iCloud address checked and unchecked) on the iMac, but only when the iCloud address was checked on the iPhone. As long as the iCloud address is checked on the iPhone, everything works perfectly.

I understand you would like to be able to set this so that only your phone number is available for FaceTime calls, but I'm not sure how the need to have the iCloud address checked is going to complicate your use. Probably my own ignorance of the process. It seems, though, that if you only publish your number, it should be the only point of contact so that it really becomes a non-issue that your iCloud address is a potential point of contact. I do recognize, however, that it is frustrating in the extreme when Apple or any other software developer takes away functionality and forces us into a very narrowly defined pattern of usage.

Best regards.

My set up was already as @justhere described, but it does not work. i think it is a bug in 8.1. worked fine before i upgraded.

I have the same issue on a new iPhone 6 (not refurb). Worked fine until 8.1. Life goes on...I'm sure Apple will fix it.

Kelly, if you'll read the entire thread you will find that this has been discussed before. In fact I had the same issue you did, with the set up exactly as justhere described but still not working. Also if you read the entire thread you will find some other steps to try in order to resolve your problem. These have worked for others, perhaps they'll work for you. Most notably, it seems helpful in many cases to set up a temporary user on the iMac in order to resolve the conflict which is causing the error on your user.

Thank you. I've read the entire thread and none of the various solutions have worked for me. I'll give it a few weeks and check back. I don't intend to waste hours on this.

In that case, Kelly, I would recommend that you call AppleCare Support. You have 90 days free as a result of your OS upgrade and they will usually allow you to pick a time for them to call you -- allows you to arrange for your best convenience. They can probably resolve your issue relatively quickly -- at least faster than pouring through online forums and banging your head against a wall. I'm surprised that setting up the temporary user profile did not work for you. Once you resolve it please come back and post your solution for the benefit of others.

Regards

To switch off FaceTime and turn it on again on the phone solved my problem too.

This has helped me - thanks!

that worked for me, I was able to turn on "iPhone Cellular Calls"

I finally got mine to work (mid 2011 MBA with OS 10.1.1 and iPhone 6 with iOS 8.1.1). After logging in/out of apple ID on both phone and mac and both FaceTime and iCloud, nothing was working. But the simple act of unchecking then (re)checking my apple id on iPhone in settings/facetime under the "you can be reached at..." section was the last action I took before being allowed to turn on "iPhone Cellular Calls" with no error message. Works perfectly now.

I was able to fix this by adding my apple ID email on Iphone at Settings > Facetime under "you can be reached by Facetime at" (checkmark). At that moment the "iphone Cellular Calls" toggle actually flipped on by itself. Then I "uncheckmarked" the email (because I really didn't want that checked) and the toggle stayed on.

IOS8. Updated on Iphone. Running Yosemite on MacPro 2010.

After trying all the suggested fixes, with none of them working, I signed out of my Apple ID account on my iPhone, and then signed back in. I was then able to Turn on iPhone Cellular Calls without getting an error message. I immediately made a call from my iMac and it worked perfectly.
