How can I change my esn number from one phone to the next for sprint..?

You know just like cingular people just have to switch their sim cards... is there a way for sprint users to do the same... say if i buy a sprint phone off ebay?How can I change my esn number from one phone to the next for sprint..?
You can call customer service and ask to have a 'Esn swap.%26quot;..and specify that you have a phone provided by you...and if it's clear there should be no problem with you doing that.... to reach them dial (*2) from your sprint phone...and hear the options...

You will need your acount information such as last 4 of the social or account pin... Good luck!How can I change my esn number from one phone to the next for sprint..?
