Bought a Droid Maxx to replace an aging iPhone 4 and set everything up and all was working well. A few days ago visual voice mail quit working and any attempt to access it or set it up again puts me in a mobius loop of either "Visual Voicemail is being set up wait 5 minutes before accessing.." or and endless loop of " Visual Voicemail is being setup...". Neither function completes and when attempting to "manually" access my voicemail it says the mailbox number is not valid. What the...? Any ideas?
