Can't send iMessage to one of my contacts!
I can send an imessage to all my iphone contacts except my fathers new iphone 5S.
He only gets my texts via cell network, but I get his repies in iMessage.
I have searched high & low but cant figure this one out.
My wife & son can both send an iMessage to him, but I seem to be the only one that can't send him an iMessage.
My phone's setting are the same as my wife's iphone.
FYI, I can Facetime his account, no problem. Just can't send an iMessage?
Anyone else have this problem?
iPhone 5, iOS 7.0.4
