I think they call it a burner phone (Phinney Ridge)
Bought in desperation when I thought mine was gone forever down a garbage can. I was never able to make it work. I think it has a phone number attached to it. It might have 120 prepaid minutes. All the original documentation plus the phone itself is yours if you are up for figuring it out.
