I have a friend who is currently in China.
We talk a lot using iMessage. The problem is that sometimes the iMessage isn't delivered and my iPhone sends it automatically as an sms (= fee !!).
I have enabled the option in the settings to do so, so that's the normal behaviour. But is it possible to enable it only for local numbers (not foreign) ?
I pretty much doubt it, but there's no harm in asking the question :)
