Anyone have VoLTE working on AT&T? My 6 shows LTE calling as an option, but it still seems to drop down to 4G. Not sure if AT&T doesn't have it working yet or if it has something to do with me using my 5S SIM in my 6 (cross upgraded)
I LOVE using my office phone at work because of how clear it is when calling out. Cel phones have always sounded somewhat crappy compared to landlines.
Having land line quality when making calls to, for example, my bank would be awesome.
