Setting a PIN password on your Samsung SGH-F480 cellphone is an effective way of keeping your data and contacts safe. However, if you forget your PIN or inherit a Samsung SGH-F480 phone from someone else who has set their own PIN, you will need to reset the phone to use its features again. You can do this by entering a special code, but you will need your cell's IMEI number to obtain this code legally.

Skill level:
Moderately Easy


  1. 1

    Call your network operator's customer care line to obtain your eight digit Subsidy Unlock code. You will need to provide your phone's IMEI number to obtain this code, and you can find this by typing "*#06#" into your handset. Write down the code the customer service representative gives you for later use.

  2. 2

    Turn off your phone, slide off the back cover and remove the SIM card. Place the back cover back into position, without the SIM card installed, and turn the phone back on.

  3. 3

    Type "#7465625638" immediately followed by your eight-digit Subsidy Unlock code. Wait a few seconds for the device to unlock. When it does so, the screen should say "Network Lock Deactivated." The phone might also restart itself.

  4. 4

    Turn the phone off again, slide off the back cover and reinsert the SIM card.

  5. 5

    Turn the phone back on and you should be able to access its features.
