Text messages being receive twice by some recipients

Question

Text messages being receive twice by some recipients:
I have had a couple of contacts tell me they are receiving text messages I send from the Z10 twice.
Not everyone thou. I've asked. I'm sending from Rogers to a Rogers user. They both have 9700's.
Any ideas?

Anyway, I followed the steps you provided, and changed all of the settings including <-- Settings <-- FaceTime and Settings <-- Messages <-- Use your Apple ID for messages.
Just to be clear, while you have to use an Apple ID for iMessage and FaceTime, you should not be using that e-mail address to receive at or send from since you're using your father's ID.  Later in your post it sounds like you de-selected e-mail addresses that were not yours, which is correct, but I wanted to make sure you understand that you should not be using this ID for a contact point since it is not yours.
If your father is still getting your text messages from your friends, I suspect that either:
(a) after making these changes you need to turn iMessage and FaceTime off for a brief period, then turn back on, or
(b) your friends are replying to older messages that you sent from your father's Apple ID, or
(c) your father's iPhone somehow has your e-mail entered as one of the possible contact points for his iPhone.
If the cause is (a) turn iMessage and FaceTime back on since you've already turned them off.
If the cause is (b) see the last paragraph of my 1st post.  Send your friends a new iMessage and tell them to only reply to that conversation and delete prior conversations.
If the cause is (b) have your father de-select (or remove) your e-mail address from his iMessage and FaceTime settings.
