Dude unlocked means you just can flash a custom or stock rom from a different provider than the phone was manufactured for. You can't just add the esn online. Verizon system will not recognize the sprint esn and will say sorry try again. Verizon has a database of every verizon phone and esn. Since your sprint esn is not on that list, that is the problem. You can try to go through the process of getting them to add it to there database but it is hit or miss on getting it to work. This is not like a gsm phone and doing a unlock and adding a sim card works. CDMA does not work easy at all to add other providers phones.
