I've moved from Apple where I could turn MMS off... there is no option with this, or with Samsung's or anything else I can find? when I write 3 short messages in one it converts it to an MMS? There is no way to stop this. So I can never never write anything more than 3 short texts worth. Apple was flawless on this... I won't pay for the full version because of this lack of being able to turn it off...
