How do I enable call waiting on iPhone?
When I'm on a call with someone it won't notify me if someone else calls me at that exact moment. For example, I can be talking to my friend and my mom calls me, it won't notify me at all and shows my mom that I'm busy. I wanna know how to fix this so it doesn't show my mom that I'm busy the moment she calls me, and I just wanna know when someone calls me when I'm talking on the phone. I'm sorry if you don't understand what I'm trying to say, if needed I will explain better.
