Not sure exactly when but since one month "volte" msg near network sign is not apearing. It was first appeared after an update after which was received before orio. I am using vodafone, network settings are correct. My colleagure uses one plus 6 and vodafone sim, for him "volte" is always displayed on screen beside network icon. Its fine if it does not appear but problem is 4g volte is not working because when i get call , though it shows "Hd" call, internet gets disconnected. this is not the expected behaviour when volte support is on. Internet ahould not get disconnected during call. Any one facing same issue?
