Other IOS devices ring when my iPhone is called and I cannot turn that off How do I change other iOS devices that ring and receive messages when near my iPhone receiving calls?
On the iPhone - go to Settings and turn off each device you wish to opt out of cals on other devices.


Settings.app
Phone
Calls on Other Devices
Turn it all off or just toggle the devices you want and don't want individually.


Messages and FaceTime work the same, and are located in settings under Phone.
