+EMPC, Unlocking or Locking Subsidy Code

The command is handling only in case of "Lock On PLMN Of First Inserted SIM" Subsidy Lock
type. This command unlocks or resets the first PLMN of the inserted SIM. Therefore, the
command is a "none basic" and will not work if SIM card is not present or if SIM card is not in
READY state. Once the subsidy unlock pin code is entered correctly to the unit, the unit is not
locked any more. In order to relock the unit a Reset action is requested. Other PLMN that will be
inserted into the unit when the first PLMN is locked will be transited to a Lock state and will not
be permitted to perform other non-basic commands except for +EMPC and emergency calls. An
error code 284 - "SIM is subsidy locked" will be returned if some non-basic commands were
entered when the first PLMN is locked. If the user exceeds the maximum password attempts (5
attempts), the unit will be transited to a penalty state and only basic command will be permitted to
perform and emergency calls. This state is effective to duration 5 minutes. An error code 285 -
"The phone is in a penalty state" will be returned if non-basic command was entered in case of
penalty state. When penalty state is over the unit will be transited to a lock state. Availability of
subsidy lock feature was determined only by the special flexing. If another flex was determined,
the command will return +EMPC: 3,0 for read command and +CME ERROR: <err> for set
command.
