When you are on a call, Call Waiting alerts you to incoming calls by sounding a long beep. Your phone’s screen informs you that another call is coming in and displays the caller’s phone number (if it is available).
To respond to an incoming call while you are on a call:
- Slide to the right. (This puts the first caller on hold and answers the second call.)
To switch back to the first caller:
- Tap Swap .
