My wife has left the android world and has gone iPhone. After updating her phone to the latest iOS version we noticed something odd yet cool happening with all other iOS devices we have here at home.
In our case it was iPads. Each started to ring as her phone started ringing. This cool feature is part of the iCloud and Facetime features.
So now the question is how to shut this off
To stop the iPhone from ringing your other devices with an incoming call, you need enter the Settings of the iPhone with the shared account
Open the settings for “FaceTime”
Toggle the switch for “iPhone Cellular Calls” and flip it to the OFF position
Exit out of Settings
