There's an HD Voice sign on my phone, what is this?

It's because HD voice is set.
HD Voice is based on LTE, which is 7 to 8 times faster than 3G, and supports clearer voice/video calls than conventional voice/video calls.

If you use LTE, you can set HD Voice.
There is no additional fee and the quality is better than the phone call when it is 3G network, so it is better to just use it.

If you go in here, you'll see how you can turn off the settings and turn them on.
