It's really bizarre that he can now make a call on the phone but NOT recieve a text (or recieve a call). I think he's switched a setting off on the phone. It's an iphone so I can't tell (I don;t use iphone). Is there an iphone setting which blocks text but allows ccalls?
OK. IT'S FIXED! We had ANOTHER go talking to China mobile, and they "reset the service" again, and we rebooted again... and now it seems to finally work.
