I got the update last night and I had problems with the Basic Voicemail activation. Call Verizon support and got it fixed, but I also noticed the LTE was on all the time even with the WiFi connected. I ask support why and was told that the Visual Voicemail now using only the LTE for voicemail, not WiFi. I again asked why and was told that it is part of the move to VoLte (Voice over LTE). That means once VoLte is fully operational, the LTE will be connected all the time. OK! My next question was will my mobile data be flowing over WiFi with voice only on LTE. I was told yes. I wait to see if that is true. As for a time frame when VoLTE is fully operational and was told soon. As a side note, my VZ Navigator will only work on LTE. When the WiFi is connected, VZ Nav will not connect to its servers. Verizon Support is "looking into the issue".
