HD Voice is a suite of services 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 calls1 (including video calls over Wi-Fi)
- 6-way conference calls
- Wi-Fi Calling2
HD Voice is included in your existing voice plan at no additional charge. HD Voice calls are billed as standard voice minutes, according to your plan.
1Not all HD Voice-capable devices support Video Calling.
2Wi-Fi Calling requires a Wi-Fi Calling-capable phone. Refer to our Wi-Fi Calling FAQs for more information.
