Most models which have OneUI6 now. Except S23 series which is very odd. Even if samsung has given it, it will work only in a few selected locations. Jio / Airtel has not yet fully implemented it everywhere.
As per your concern, we want to inform you that there are no specific details available right now, our team is working on it, every device who are 5G will get the VoNR feature soon, kindly wait for it.
