Messenger, Instagram calls not working while using Mobile Data
I have observed that when someone tries to contact me through these applications while on data, I get the notification that they are trying to contact me but the call will not push through after accepting it. Everything seems fine while using wifi. I have an iPhone XS Max with a physical dual sim. Turning off one of the cellular lines and/or turning off the VoLTE of the second cellular line seems to fix the issue. But it’s annoying to do it everytime. Does apple have a fix for this?
