Hi Reddy,

You can try calling 1633 and ask the CS if HDVoice is enabled.

Hope it helps!

Ask them to switch off and switch on again.

meanwhile do i assume you are using apple? IF yes. make sure 4G is on for Data and voice and not just data only. If it's already on data and voice, do the same thing. Off 4G, then on again Data and LTE .

Just something that's probably out of the point. but it's worth a try.

1) Reset network settings on apple and try out i did that on mine and worked.
2) Upgrade iOS? For iOS 13 thats a manual option on the phone to off and on..

 

I suspect its either reset network settings or what. What's the starhub version on your phone? Under about.

 

There was some known issues on iOS12 with voLTE and was only fixed after iOS 12.3.1
