I am using an iPhone 6S as my primary work iPhone. I have an old iPhone 4 that I am trying to use as a dedicated baby monitor.
The iPhone 4 has had its SIM card removed, but it maintains WiFi access to our network.
Both are using the same apple ID.
Whenever my iPhone 6S receives a phone call, my iPhone 4 still shows an incoming call. I have gone into phone notifications and disabled everything. I'm not sure what else to disable to prevent it from ringing. Any ideas?
Both are running the latest IOS (10.3.1).
