VoLTE has gained the option of using a higher bitrate codec than has been in use since the early GSM days. And the GSM bitrate and codec was chosen to pack as many voice calls as possible into the bandwidth of the GSM protocol.

That said, if it is iPhone to iPhone, it may well be that the call never touch the carrier systems and instead happens over iMessage for all i know.

That would only happen if you are using Facetime Audio

Do you have to opt in on every call, or will it happen automatically as with messages?
