My parents' old Motorola W385 will no longer be usable as of Jan. 31. I have already bought them a new phone compatible with the network and installed the Koodo SIM card, which the Koodo staff at a kiosk programmed with their number. It's working fine. I'm wondering what to do about the old phone. Do I need to officially deactivate it or take it off their account or will it just "die" when the network shuts down and I don't need to worry about it?
