I was recently told that my voicemail inbox was full, which I thought was strange because as soon as I get a notification, I check it and delete it. After thinking about it, I haven't got a notification for a voicemail in a very long time. I checked my voicemail and it was full, so I deleted everything. I them did a test call and left a message. I never got a notification. A long time ago, I disabled the verizon voicemail app because I thought it was only for visual voicemail which I don't have. I wonder if the app being disabled is not allowing notifications. The problem is that I can't turn the app back on. All my other turned off apps have a option to turn on. The verizon voicemail app only has a disable button and it is greyed out. It almost seems like the app is turned off, but my phone thinks it is on. But with no option to turn on or off.
