Does the Samsung Galaxy S4 SGH-I337 support VoLTE aka HDVoice ?

For information on HD Voice, including capable devices and current HD Voice coverage areas, please visit att.com/hdvoice And don't forget to click on the FAQs!
I know the S4 Mini does. So, that might imply the S4 does too.
It does, but enabling it is non-trivial. If you google for Galaxy S4 HDVoice you will find several sites walking you through the specific sequence in the dialer to get to the setting to enable it.
How can we improve?
