Both the phone and the sim card would be new, meaning I would purchase an unused sim card separately.
Is that possible? Could I just go online and activate the card?If I buy a Motorola Razr V3i can I get prepaid service simply by inserting a new Cingular Go Phone sim card ?
If the RAZR is also a Cingular, then you should be able to swap out the SIM. The SIM is just a way to identify you on their network, so as long as it's compatible with their network it doesn't matter what phone it's in. If it's a Verizon phone you won't be able to use it cause their network uses CDMA.
