How to Enter Unlock Codes on BlackBerry 6xxx 7xxx: ie 6230, 7100, 7290 etc..

ENTERING CODE:

Now select Options menu on BB.

Now you select SIM CARD menu.

To be able to see this you have to type this on the keypad on phone : (TEXT WILL NOT APPEAR ON THE SCREEN until you enter the unlock code)

Type 'MEPD' for all models except 7100 in which case in case use 'MEPPD'.

Usually u should see "active" NET lock. Now in order to disable this lock type 'MEP2' respectively 'MEPP2' if phone is 7100 and will appear a dialog asking for code.

NOTE: You must use the "alt" or "shift" key to enable numbers so example would be: m-e-p-"alt key"-2

Now you should see the place to enter your net unlock code.(if not, you didn't type in mep2 or mepp2 properly.)
