The operation couldn't be completed. (AKAuthenticationError error -7005.)
For months now I have not been able to use my mobile phone at home.
We live in a rural area, so this was even more frustrating for me.
Adding to my frustration was heading into work, 1/2 an hour away, and I would then relieve my messages and voicemails - because I wasn’t receiving my calls.
Adding to this issue I run my own small business - so I’ve lost some pretty good money from this issue.
I have been on here and tried several things that didn’t work, until today. When trying to reset my phone (for the umpteenth time) I received this message… and I couldn’t even screen shoot it, so took a photo with my iPad. LOL.
I’m posting this now so that anyone else having this issue can try the solution that I found worked. See Best Answer below.
