FAQ:

Question: My phone asks to enter a PIN number
Answer: For SIM cards with PIN ENBLED 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 then what is shown in this procedure 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 inserted correctly – Gold area downwards and the cut of the corner matches correctly. You will need a working Non Vodafone SIM card to unlock the handset, Vodafone can not assists with other networks faulty SIMs.

Question: I am outside of Australia and experiencing difficulties unlocking the phone that I purchased from a Vodafone Australia outlet
Answer: Clearly note this in the difficulties description. Vodafone Australia can only send a reply to the difficulty by email.
