What is HD Voice?
HD stands for High Definition. You might have heard it used in reference to TVs and picture quality, but it also applies to the quality of sound. HD technology dramatically improves the quality and clarity of voice calls, so when you’re talking to someone it sounds much more like you’re talking to them face-to-face.


How does it work?
The technology works by opening up the phone’s audio range, allowing it to capture and transmit sounds across a wider band of frequencies. This makes HD Voice calls sound clearer and more natural than a standard mobile or landline call.


Is it available now?
Yes, to make an HD Voice call both the caller and the receiver need an HD Voice equipped phone and you both need to be on the Three network.
