PUK Code
PUK stands for Personal Unblocking Key. This is a unique eight-digit code specific to your SIM card. This is required when the PIN number to unlock your mobile phone is entered incorrectly 3 times. You are then given 10 attempts to enter your PUK code. If an incorrect PUK code is entered after the 10th attempt, you will block your SIM card permanently and will require a new SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways - The PUK code is in your SIM card documentation Starter Pack. If you do not have this then - Please contact your phone service provider.
Your cell phone service provider can give you the PUK code once you give them your account details and they have confirmed your identity. For details to obtain the PUK code for the SIM card, please click on this link and follow my instructions.

PLEASE BACK UP YOUR FILES BEFORE UNLOCKING
This will also bring the phone to default settings
1. First do a CUSTOM reset: *2767*2878#
turn off the phone
2. take out the battery and sim and put wrong network SIM and insert only a half of it,
Very important so it won't ask for network password and shows "Insert SIM" message.(possibly in a different language)
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.)
3.push the sim fully in at this stage the phone is still asking to "Insert SIM"
4. Make a FULL reset: *2767*3855#
5. The phone should reboot working with "wrong" sim inside.
6. Make a Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#
7. Now Disable network lock By typing: #7465625*638*00000000#
Phone is unlocked

Please advice how to put this phone in use. Model- Blackberry curve 8900

Try resetting the phone, the hard reset on the phone, you need to take off the battery of the phone then remove the sim card. After that place the battery back without the sim, please enter *2767*3855#. Just a reminder everything will be deleted on the phone, it will restore back to the factory settings. If this procedure would not help the phone needs a reflash.

The above code works. When it says insert sim card, simply start typing in the code. When complete it will tell you it is resetting and will restart by itself.
