How to Unlock a Nokia With the PUK Code


Nokia phones that operate on Global System Mobility (GSM) have a special security feature to protect the SIM card. When enabled, a numeric code -- referred to as a SIM PIN -- must be entered before the device can be used. Multiple wrong entries of a SIM PIN will prompt you to enter an additional code, called a PIN Unlock Key (PUK). The PUK is an eight digit code. Your PUK is specific to your SIM card, and must be obtained from your service provider.

  • Contact your wireless provider to request the PUK code for your device. Most providers have a toll free customer service hotline -- find the number on a recent bill or company website. You will need to verify your account details, such as a phone number and security code, before the PUK can be released to you.

  • Press and hold the "Power" button on your Nokia phone to turn it on. When the phone is locked, an "Enter PUK" message will display on the home screen.

  • Use your keypad to type in the eight-digit PUK code. Press "OK." An "Enter New PIN" message displays.

  • Type in a new four-to-eight digit PIN code of your choice. Press "OK."

  • Re-enter the new PIN code when prompted to confirm. Press "OK." Your Nokia will now unlock.

Tips & Warnings

  • You can disable the request for PIN and PUK codes. From the main menu, choose "Settings," then "Security Settings." Choose "PIN Code Request" and select "Off."
  • Do not attempt to guess your PUK code. After 10 incorrect entries, it will become permanently blocked.
