@Lucifer96 use force lte app to enable nr only mode and then check if you are still able to place a call or not. If it work then your phone is vonr enabled but disable in settings. Samsung phones have currently disable vonr due to its inconsistency, it will enable in future updates.
Bro... It's literally showing on your phone that you're on VoLTE. As I've said on the forum before, just because the data service on your phone is connected to a 5G network doesn't mean your calls are also VoNR. Data and voice are handled independently of each other on your phone. And Jio is still in testing VoNR as far as they've announced.
Good to see that Vivo also supports VoNR. It seems that they're slowly allowing VoNR for each device after testing. For me VoNR on my OnePlus started working since December starting itself but it's still unstable
@pillaicha What the phone shows doesn't matters. And what ur saying is NSA feature where data goes via NR and calls via LTE simultaneously which is not possible on SA. I think u aren't understanding the meaning of "Standalone"
