What is Voice over LTE service
                                                
                                                
                                                
                                                
                                            
                                                                                Sprint is suppose to be the first carrier who has Voice over LTE service. I'm not sure what the big deal is hear. Doesn't it already carry voice over the cell towers. Can anyone explain to me why this is such a big game changer. ?
