0000, unless you changed it.

You can usually call your mobile service provider and have them reset your pin codes to the last 4 digits of you phone number.

security code

The default PIN code is 0000 on your BlackBerry device. This is for the SIM pin only, and may not refer to any other lock you may have installed on your phone.
If you've forgotten your PIN, simply enter the code incorrectly three times, until PUK blocked shows up on the screen. Call your carrier and get the PUK code, which when correctly entered, will ask for a new PIN code.
If you've forgotten any other password that you've set up, you'll need to have the phone reflashed by a professional.

contact ur service center....

I have forgotten all lock codes of my phone nokia...

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Hi your only option is to call your phone service provider, no it doesn't come with the phone and the phone never has its own puk code becouse the puk code is about the sim card.

if you put in another sim card the phone will work just fine, its the simcard 3 times pin code wrong puk code enabled pin blocked, call service provider to get it and entery instructions.

Let me know if you need anything else.
Thanks,
