How do I get my voicemail back to the default greeting? I've tried what feels like everything, but I keep getting an error message (com.apple.mobilephone error 1035). Has anyone else had this issue/been able to fix it?
I don't know the answer off the top of my head, but there's device troubleshooting available on the website if it's a Verizon variant iPhone. An internet search engine ought to provide some details.
