Hello there! In order for us to be able to unlock the device, the account information is needed. We need the phone number and the security PIN or the answer to the security question on the account that the device used to be active. As soon as you gather that information from the previous owner, you can reach back to us for further assistance. You can have more information about our Sprint unlock policy in this link http://sprint.co/1P2a4T2
Good morning Lopez.
Now that you have the information required to unlock the device, we will need to contact you. Our Account Services Department will do the rest. We just sent you a Private Message, please reply back as soon as you can.
