Hi. I had what I think is quite a familiar problem with Imessages sent by other people to my iphone being picked up by other apple devices attached to our family Apple ID. Obviously these could be unchecked on these devices but a nosey child can easily re-tick them. I created a new Apple ID and set my Imessaging to this new Apple ID in Settings > Messages > Send & Receive > Apple ID. My number now no longer appears as an option on the Send & Receive bit on my kids' ipads. Does that mean they definitely won't receive my imessages? Sorry I know this sort of thing has been asked before in all likelihood. Many thanks.
