sorry.. all the advice here is useless .. if the seller gives you a good esn to check.. but sends you a different phone with a different esn!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
of course they could be honest.. which there are honest sellers out there.. but if you are unluck to get one scammer.. your $$ are gone
only one real way to do it.... this is what I do....
meet at a sprint store! have them check the esn on the actual phone... if it is good.. then pay.
