Why is my Nokia phone requesting a PIN/PIN2/PUK/PUK2 code? - Nokia FAQ
Your Nokia device requests PIN (Personal Identification Number) and PUK (Personal Unblocking Key) codes to protect your SIM card and device against unauthorized use. Note that all PIN and PUK codes are provided by your network operator. Nokia is not able to provide you PIN or PUK codes.
Please note the following:
- When your insert your SIM card and boot up your device for the first time, you need to enter the PIN code. For security reasons it is recommended to change it to your own code, instructions on how to change the PIN code in your device is provided in the user guide or Nokia web site. If the PIN code is entered incorrectly multiple times, your device may request a PUK code to futher validate the user's identity and to unlock and change the blocked PIN code.
- The PIN2 code is a PIN code which acts as a second layer of protection for certain features of your phone. If the PIN2 code is entered incorrectly multiple times, your phone may request a PUK2 code.
If you have forgotten or simply do not know the codes, you must contact your Network Operator for assistance. However, if you have already contacted but the code does not work, you should consider getting a new SIM card from your Network Operator.
My Nokia phone displays "SIM card rejected" or "SIM card unaccepted". What can I do? - Nokia FAQ
These kind of messages are displayed in the following situations:
- The SIM card may be out of alignment. If the phone has recently been dropped, bumped, or opened, the SIM card may need adjusting. Follow the SIM card installation instructions in your phone user guide.
- The PUK (Personal Unblocking Key) code is entered incorrectly multiple times. This can inactivate the SIM card. If inactivation appears to be permanent, contact your operator or service provider for a new SIM card.
- You have recently changed your mobile operator or mobile service provider. In this case, either your SIM card or your phone settings may have been configured for your previous operator and therefore reconfiguring is needed.
- It may also be that your phone is simlocked, so using a SIM card from a different operator or service provider is prohibited. Please contact your current mobile operator or service provider for further assistance.
If none of the situations above apply and you continue to receive this error message, your SIM card may be damaged. Please contact your mobile operator or service provider. Or alternately, contact your local Nokia Care Point for inspection.
