I have a new Motorola C139 phone that was given to me by a friend who recently returned home from the USA. The phone is registered with TracFone for prepaid services. The manufacturers sim card has been misplaced and there is no way this phone can be activated. Can you help me go through this?

I have a C139 from TracFone too. My sim card got locked and I called them and they are replacing it for free. If you still have the card where you punched out the sim card, you will see your sim card number. If you can't find it, try calling TracFone's customer service.
