To add to what pio_masaki said, to get to your EPST settings you dial ##778 or ##778# and then enter 000000 and click on edit. Be careful what you do as changing anything can mess everything up. But overall and as others have said, your carrier should need to change the ESN but rather add it to thier database. If they need to know what the ESN is then they also can look under the battery.
