How to add native VoLte support on G930T?

[manigma]

I am on latest firmware, no root. Why T-mobile disabled VoLte

I just downloaded the November security update, and VoLTE is enabled as it was before updating.

I've had it since I've been on the UnCarrier side of Tracfone (which is since I've had it active). Before I had it active, I was piloting a Galaxy Nexus (which supported neither VoLTE or VoWiFI); while it claimed to support LTE, it was trapped with LTE band 13, which does NOT support that LTE feature set very well, nor does it support VoLTE at all). I just re-enabled VoWiFi as a test (running the AT&T Oreo firmware - still on T-Mobile side of Tracfone).
