It works! This is AWESOME! I didn't set anything up in my account at all... I just popped my sim in (used an upgrade from another line - did the whole "keep unlimited switch-er-oo") and noticed a new menu in the "Cellular" menu. Switched Data to Voice + Data and was able to make a call, over LTE! EDIT: I'm hoping others can chime in here. Is VoLTE working for you? Is this a regional rollout or national? iPhone 6 on Verizon in Hartford, CT here.
