How to unlock your Blackberry 8520 - Using the unlocking codes

General Information about the BlackBerry unlocking codes

When you receive your code it will be in one of two formats (depending on your model)

1: A single string of 4 or 5 long numbers or
2: Again a string of numbers, but with some identifying letters between them (EG MEP/NCK etc)

If you receive format 1, then these are simply 4 or 5 codes that need to be tried. (So when you are asked to enter the unlocking code, you need to try each one, starting with the 1st).

If you receive format 2, then please refer to the table below for your code.

Please make sure the wireless mode is turned off before attempting to unlock your Blackberry phone

FAQ:

Question: My phone asks to enter a PIN number
Answer: For SIM cards with PIN ENABLED you will be required to enter a PIN. This is not the unlocking code that has just been provided. For information concerning the PIN, PIN2, PUK and PUK2 codes for a SIM card please read the manual that came with your phone. This is NOT a handset unlocking difficulty.

Question: My handset displays a different message to what is shown when I insert a Non Vodafone Australia SIM card.
Answer: The most common message the phone will display is 'Invalid SIM card'. Because each handset may have a different variation in software there is no common message. If your handset displays a different message it is recommended to move onto the next step. Note: Faulty SIM Cards - The handset may also display messages indicating the SIM you are using to unlock the handset is faulty, it could display 'Insert SIM' 'Bad Card', 'Card Error' or 'Card Rejected', confirm the SIM card is correctly inserted, the gold area downwards and the cut of the corner matches correctly. You will need a working Non Vodafone SIM card to unlock the handset.
