Root Eco 4G to criket

[galaxyesm]

Hello...just bought a Eco 4G of a friend but I'm guessing it has a bad ESN guessing he stopped paying it or something...does anyone know if I can turn it into cricket w/O me going and paying them 40$ for them to do it. Then charging me another 40$+/- for get it connected?

Phone is not rooted its on the original stock mode.

TIA.
