WHAT IS CELL PHONE CLONING?    

 Cell phone cloning is copying the identity of one mobile telephone to another mobile telephone. Usually this is done for the purpose of making fraudulent telephone calls. The bills for the calls go to the legitimate subscriber.

You would also have to change the MIN (Mobile Identification Number). When you had successfully changed the ESN/MIN pair, your phone was an effective clone of the other phone. Cloning required access to ESN and MIN pairs. ESN/MIN pairs were discovered in several   ways:                                                                                                                             ...
