Iphone 14 Voicemail won't set up greeting com.apple.mobile-phone error
My Iphone 14 Pro Max with IOS 16.01 voicemail greeting wont' set up. It says I do not have voicemail set up when I call my number. Every time I try to record a greeting I get the error message "The operation couldn't be completed. (com.apple.mobile-phone error 1035).
I have tried turning my phone on and off. I have tried resetting the network settings. I have tried Wi-Fi on and off. Nothing works.
What else should I try?
Thanks
