Phone number not associated to iPhone

I HAD the same issue. I tried a lot of steps and finally saw a simple statement that WORKED! I clicked where “in red” it said to remove the number from iMessage and FaceTime. Then I backed out of both iMessage and FaceTime and went back into them and selected my phone number again when it popped up. THIS FIXED IT in 1 minute after I had spent 45 minutes going through threads and turning stuff off and on, and rebooting several times. I hope this can help someone. It should be at the top of the “fixes”

Please refer to the pics below. If the number on Pic 3 and 4 are the same on your device and there are no other numbers on the Apple ID

Then you are using a SIM which has a Phone number different from these then you need to change the Apple ID Contactbale and iMessage by disabling Imessage and Face Time First.

I didn’t quite follow dapicso’s method but similar.

I turned off iMessage and FaceTime; I did turn off the phone for a few minutes (though I don’t think this matters); then WITH IMESSAGE AND FACETIME OFF I changed My Number under the Phone settings.

‘Save’ didn’t seem to do anything this time (it had been changing right back to the temporary number from my SIM) but I just used the back arrow and the correct, updated number stayed.

Now I went back to switch on iMessage and FaceTime and found that my proper number was no longer on a timer and the temporary SIM number was no longer an option. Hurrah.

HEY GUYS,

This is my 1st comment in this community, also just want to help everyone experienced the same issue.

Go to Settings -> Search My Number -> Click on My Number and put in your correct number -> Turn off iMessage & FaceTime and turn back on -> Wait for 2 mininutes -> Choose your phone number -> DONE

100% WORK

I just took the SIM card out, tried another one and put my original SIM card back in. Now the SIM card and the phone don’t seem to recognize each other.

For Messages, choose Messages > Settings, then click iMessage. For FaceTime, choose FaceTime > Preferences, then click General. Turn your phone number on or off: To turn on your phone number, select it and your Apple ID in the list.

Add or remove your phone number in Messages or FaceTime

1. Is this your corporate iPhone? Then please contact the system administrator of your corporate
2. If it is your personal device, in that case, do you have any profile installed by your corporate/organisation/enterprise/School Management?
   1. Erase the profile added by you If you have installed a profile on your own --> Install or remove configuration profiles on iPhone - Apple ...
   2. Or please contact the system administrator of the organisation who provided the profile to you

Watch this GIF for better understanding the phenomenon

This message indicates that the phone you are currently using with your Apple ID is different from the one associated with the phone number that you are using for iMessage and FaceTime.

I was hopeful that your fix would work for me, but unfortunately I’m still bugged. ):

I've spent ages trying a variety of remedies for exactly this issue: switch the phone off and on, take the SIM in and out, send an SMS, contact network provider, stand with one leg in a bucket of tepid water, and all possible permutations of these.

Finally sorted thanks to you.

Thank you so much, I have spent way too much time on this not knowing who to call I called my new provider and she said everything went good on her end so that was not very helpful she had no recommendations. And as the days counted down I became more concerned and all I had to do was exactly what you did. Thank you for sharing.

Just adding a me too on dapicso’s solution - Once you receive confirmation the phone number has switched over, remove the your time limited number, back out of the FaceTime settings. Go back in and select the mobile number that came with your sim. After a few moments the number changes to the number you transferred and then works. This also fixes ‘my number’ in the phone preferences.
