(SIM-lock is NOT the SP-lock/Service Provider lock!!)

The SIM-lock makes your phone to fusion with the SIM-card, and the
phone will not accept any other SIM cards after you lock your phone!
You get ten chances to type the correct code! After the tenth time
your phone gets "SIM-lock permanently blocked", and you will be
unable to open it !! The best thing you can do is to remove the
SIM-lock permanently!!

The 54# Tip
Type 1#, 2#........54# on the keypad (when you're not in the menu)
to get the phone number used for with this key when speed dialing
