How to Enter Unlock Codes on BlackBerry Storm

All new phones are locked to the network that they are purchased from, as a result you will be unable  to use a SIM card from a different network on your phone . You must have a SIM card in your phone to complete these steps, I have found that this procedure works best with an AT&T or Cingular Sim card in the phone (can be active or inactive ). Make sure the phone is not displaying the low battery warning!

  • Ensure a SIM Card is inserted
  • Go to ‘Manage Connections’
  • Click on ‘Turn All Connections Off’
  • Go to ‘Options’
  • Click on ‘Advanced Options’
  • Click on ‘SIM Card’
  • Tilt the phone horizontally, click the BlackBerry button and Show keyboard
  • Type ‘MEPD’ (letters will not appear on-screen but a menu will pop up.)
    • *If MEPD doesn’t work, try MEPPD
  • Type ‘MEP2′ (user will be prompted to enter MEP code)
    • *If MEP2 doesn’t work, try MEPP2
  • Enter the MEP2 code (CONFIRM you get “Code Accepted” message)
    • *If you also have a MEP4 code, type ‘MEP4′ (you will be prompted to enter MEP code)
    • Enter the MEP4 code (CONFIRM you get “Code Accepted” message)
  • Reboot device
  • Go to ‘Manage Connections’
  • Click on ‘Restore Connections’
  • Device is now unlocked
