Bloodninja, you seem to be under the asumption that the SIM card has something to do with cell phone calls, it doesn't. A SIM card is nothing more than a memory chip that contains the basic information the cell phone needs to act as that particular SIM card owners phone, all the actual work is done in the phone itself. You can't use a SIM card to initiate a phone call without a phone to place it in, again it's nothing more than an encrypted information storage device, although it has been possible for years to copy SIM cards.
