Like it sounds, a used mobile phone is one that has had its problems fixed, but it is not necessarily under warranty and may or may not have been cleaned up. Because of the large number of cell phone models available and the speed at which new models are created, it is often more time-consuming and expensive to repair a mobile phone and recycle other electronic devices, such as pagers and personal digital assistants (PDAs).
