Not sure if it's related, but I also don't get voicemail notifications. I manually checked yesterday after my wife said she left me a message and I had almost a dozen from the last month that I never received notification.
I think I'm just gonna do a factory reset for now. If that doesn't work I will call Sprint.
What area are you in? I have some experience with being connected to 4G but not being able to use anything on the network at certain times because 4G is not officially launched here and it is still in the test phase. Also there are tower overloads that happen because backhaul is not installed yet. Try to switch your phone to CDMA only to see if you are getting the same errors on 3G as you are on 4G. Also keep track of what areas you are having the problem. If you want to get real techy, open your Dialer and enter ##DEBUG# and then go to the LTE Engineering screen. Here you will see the site ID (Tower ID) that you are connected and the signal strength. You can just write down the site IDs and maybe a pattern will emerge of sites that are having issues at certain times during the day.
