Wifi calling provides an indicator so that the user knows that wifi calling is engaged: very useful when roaming abroad.

Is there a similar indicator to enable the user to understand if VoLTE is engaged and not cellular: this would be helpful to understand if a call is using accruing roaming fees, when out of network.

For me, it’s painfully obvious that the call quality is much better on VoLTE and FaceTime audio calls.

There is no indicator, so you’d need your carrier to break that out if you can’t record or tell from the higher quality and larger frequency range / response.

It’s of course possible a carrier could direct you to VoLTE and the codec degrade, so this isn’t a guarantee, but it is striking enough that I generally can hear the difference.
