Lock Phone
The Lock Phone option lets you Lock or Unlock your phone
immediately or set your phone to lock itself On Power Up.
Locking the phone blocks all outgoing calls except those to 911 and
to any other user-programmed emergency numbers. You can lock the
phone manually, or set the phone to lock automatically when turned
on. In Lock mode, you can answer calls, but you must unlock the
phone to place calls (except to emergency numbers). (For more
information, refer to "Emergency #" on page 137.)

programed into NAM2, you won't be able to access your phone. You
must call your Wireless Provider's Service Center to unlock your
phone.
