After much complains on the VolTE issue, Oneplus developers finally get it into their thick heads to enable our local telco VoLTE settings into the modems. But still they would not put in VoWifi and hence why many are still not getting VoWifi. Tbh, Im sick and tired of these jokers already. Seems they are not to keen on making the phone user friendly for all. Come on VoLTE and VoWifi are standard settings that should work out of the box and here we are still needing to mod it here and there to make it work. Dont even get me started on 5G.
