When you're talking on your iPhone and another call comes in, your iPhone will display the caller's name or number along with the following options: Ignore, Hold Call + Answer, and End Call+ Answer. (More on switching between calls below). However, you may find these options unnecessary or even annoying if you seldom use them. In this case, you can disable the Call Waiting feature by following these steps:
- Open the Settings app and go to Phone >Call Waiting.
- Switch the Call Waiting button to the OFF position.
