SIM card / PAYG Help
Sorry for the stupid question... I recently bought a spare phone, and would like to buy a pay-as-you-go type of plan for it. I see people selling SIM cards from Rogers/FIDO on the BST forums... can I buy a blank SIM and somehow set it up to use PAYG? Or do I have to go to a retail outlet and get the store to set one up for me? And if I can't setup my own SIM, why are people selling new/blank SIMs? What good are they?
