My visual voicemail on my Droid 4 is requireing me to resign-up for it every time I receive a new VVM notification. I do not have HandCent on my device, so I can rule that out. I have spent hours on the phone with Verizon and gone through 3 phones, but noone can seem to fix my problem. After I am signed into VVM, I can go in and out of it as much as I want --- until I receive another voicemail that is. Has anyone else had this problem? Any Ideas??
