Can't iMessage overseas friend?
I'm from the UK and my friend is from the US.
We're trying to use iMessage over email (we don't have each others phone numbers), but when she send a message to me it fails, and when I send one to her she never receives it.
I don't know what the problem is, I'm sure it ought to work?
I've googled a lot and can't seem to find an answer so I'm asking the question directly.
I am on the latest iOS 7.0.2. and she is on iOS6 but says she doesn't have any trouble messaging other people?
(I've tried emailing her from my phone and that does work)
