I have a Few month old Motorola Trumph, that has the $25 service that will be going out in 5 days due to my company bought me a phone from Virizon. I want to sell the Trumph, how do I keep from the ESN from going bad? I have heard after it becomes inactive the ESN is no good for 120 days. Should I change service so the account ends on my LG Optimus V? Will that save me from waiting 120 days?
