An ESN is an electronic serial number used to identify a specific code division multiple access, or CDMA phone. A CDMA cell phone does not use subscriber identity modules to identify and authenticate subscribers to the network. You cannot activate a cell phone with a bad ESN on its manufacturing carrier due to several reasons. This can be due to the fact that the original owner was dissatisfied with the carrier and switched carriers, or had a billing dispute with the carrier and canceled service without paying the early termination fee, or he got behind on the bill. The ESN can also be bad if the cell phone was reported stolen or lost, or if the phone is still active on the previous owner's wireless carrier account.Learn more about Mobile
