I have an HTC Ozone, and i tried changing the voicemail number from #1 to #3, and when i did that i was unable to get to my voicemail. So i tried changing it back to #1 and it still won't work. I never had an actual voicemail set up, like a voice recording or anything and it worked before i tried changing the number. So how do i get to it now?! I have voicemails i need to check ASAP.
