iMessage appears to be blocked, but FaceTime rings Something confusing happened on my iPad today. One of my contacts' number has been red instead of blue in iMessage for sometime now. I cannot send them a text through iMessage. The send button isn't even active with their number. I know that typically means I am blocked or their number is no longer associated with their Apple ID.

However, today I decided to try FaceTime on that number. It rang more than 6 times. There was no answer. But why would it ring if the number doesn't work with iMessage?
The reason is because the person your are messaging turned off their Apple ID from iMessage. You’re iPad is trying to send a text message but because you’re not on an iPhone it can’t.

FaceTime was ringing because the person didn’t turn off FaceTime but only iMessage.
