Verizon quickly followed up its plans to use Voice over LTE (VoLTE) with word that it was the first carrier ever to make a phone call with the standard. A call at 9:54AM Eastern on Tuesday with an LG Revolution lasted for just 33 seconds but was followed up by tests to prove simultaneous data and voice would work. Calls lasting over 10 minutes included browsing the web, chatting or downloading apps in the background.
