Iphone 11 incoming call during other call
Hi,
I have an Iphone 11 (my first iphone) and when I'm in a call and someone else is trying to reach me, they get the sign that I'm busy with another call. But I don't get a notification that someone else tried to reach me during another conversation therefore can't call them back.
What can I do to get a notification during a call if someone tried to call me?
Thanks
iPhone 11
