I have a voicemail notification that will not go away. When I select it to listen to the voicemail, it will say "The person you are trying to reach is currently unavailable. Please leave a message after the tone." I have tried pressing pound, *, 8, all other kinds of options and suggestions I have read online to try and sign into my voicemail, but to no avail. This problem started yesterday out of the blue. I used to have my voicemail set up, but I'm assuming right now that I don't. I can't set it up either, since every time I try to call my voicemail, I get the same message played back to me. While I can receive phone calls, others hear the same message played back if I do not answer. If they do leave me a voicemail, I certainly do not know where they are going. I have tried restarting my phone; I have tried removing the battery; i have tried everything under the sun shy of going to my service provider, and would like to leave that as a last resort since the almost always just suggest a factory reset. Any suggestions would be greatly appreciated!
