With AT&T shutting down it's 3G network in a few months I was wondering if anyone had been able to get AT*T's voLTE (HD voice) activated so we can still make voice calls on the network. I have the AT&T model (and am using a tracfone AT&T sim), and "search" in the settings does show an entry for "enhanced LTE services" but selecting it just takes you to the same spot as the "more" entry and there is nothing useful for voLTE. When making a voice call data drops out of LTE, down to "4G".

Using a t-mobile sim (via tracfone), defaults to voLTE, verified also by surfing during a phone call, and LTE symbol staying on the whole time.

Hmmm weird, I can get voLTE with another AT&T MVNO (unreal mobile) by default, with no issues (also tested by surfing during a call and having LTE symbol stay on). I was not aware there could/would be differences in voLTE support among MVNOs
