Call Waiting - Apple® iOS
Here's how to answer call on your iPhone while you're on another call.
If using multiple SIMs, only one mobile number can receive calls / messages or use cellular data at a time. If two mobile numbers are activated on the device and one is on an active call, calls to the other number rings through to Voicemail but the incoming call doesn't appear on the screen. After hanging up on the active call, a missed call notification will be visible, as well as a Voicemail "new message" indicator if the caller chooses to leave a message.
When you're on call and a second call comes in, you'll hear a tone to let you know that you have another call.
- To answer the 2nd call and place the 1st call on hold, tapHold and Accept.
- To switch between calls, tapSwap.
- To end the call(s), tap theRed phone icon.
