To order an Unlock Code for BlackBerry models OS10 (Z10, Z30, Q10, Q5) as well as BlackBerry 9315, 9320, 9720 we just need the IMEI (Serial Number) of your BlackBerry. But for any other models (the oldest BlackBerry), we need either “IMEI + MEP” or “IMEI + PRD“. Finding the PRD of your BlackBerry is the easiest solution (click-here to see a method for finding the PRD of your BlackBerry) however this is not the most accurate method and many requests for the unlock code come back as “Not Available” using this PRD method. In this situation its best to find the MEP of your BlackBerry, and below is the simplest method to do this using the Original USB Cable of your BlackBerry and a Windows computer.
