How to Fix a Bad ESN: A bad ESN isn’t an issue with a telephone, it is a problem with the cellular carrier. ESN is brief for Electronic Serial Number, the individual positive identification that identifies CDMA phones to the cellular network.

The initial account holder will contact the carrier and clear up any remaining balance before the new owner can activate it. Activate the phone on another carrier’s network.
The ESN is merely bad for the carrier the phone was originally activated on. There are several CDMA carriers that will accept phones from other networks.
If you go this route, you may just have the phone flashed. Flashing deletes the initial carrier’s settings and substitutes the settings for the new carrier.
Carriers that accept flashed phones usually have stores that may flash the phones for you for a fee.
