Insert not original/invalid card into device and redetect it, if it's locked it should say Sim Lock Status: locked. Then you'll be able to unlock it.

thx a lot, so I unlocked it successfully, after 4 credits
just one work of advise I need to ask, is this unlock permanent? provided I can use my operators and other operators sim card back and forth? & do not update the firmware or software whatsoever?
