HD Voice is enabled by VoLTE (Voice over LTE) technology. VoLTE delivers voice calls over the 4G LTE network instead of the traditional voice network, providing clearer, more natural sounding audio when both parties are using HD Voice-enabled phones that are connected to our 4G LTE network. HD Voice also includes additional benefits such as:
- Simultaneous voice and 4G LTE data
- 1-way or 2-way video calls
- 6-way conference calls
