Not Able to Connect on FaceTime Between Apple Decices on Apple ID Family Sharing
I just gave my 6 year old son my iPhone 6S+ after upgrading to an iPhone 7. His iPhone doesn’t have a SIM card, the idea is for him to be able to use it on WiFi to FaceTime his Mom when he is with me and vice versa. The problem is when he calls me or I call him on or from my iPhone, after accepting the incoming call about 80% of the time the call doesn’t ultimately connect and instead just times out. What is strange is I can almost always receive his calls on my iPad, which is logged in under the same Apple ID as my iPhone,, but the same problem happens if I try to call him from that same iPad, it just doesn’t connect.
One last thing, he can FaceTime everyone else in the family who I put as contacts in his phone just fine. I’m wondering if the issue is that I set his phone up with an Apple ID under my own ID (it’s an iCloud email address using family sharing). But if so why would it work OK when he calls my iPad?
Any and all advice would be appreciated.
