[Skunkworks] ORANGE IPHONE

I was trying to get an iphone from orange for prepaid one has to pay 30k which is a 6 months contract @ 5k. My question: Is it possible to LOCK a sim card to a phone(iphone) since they say you can only use the sim on that phone ONLY? nerdalf. -- One who asks questions is a fool for 5 minutes one who doesn't ask questions is a fool forever.
