Unlocking ZTE san francisco

[Guest johninbkk]

I am trying to unlock my ZTE blade but I do not have the NEW SIM card security code

<LI itxtNodeId="36" itxtHarvested="0">(If prompted, enter any personal [4-digit?] PIN number that you may have set on the new SIM.)

where do I go from here?

I've had this old sim for years and never had the need to use the security code, therefore I do not know it. <BR itxtNodeId="60">
