+EMPC, Unlocking or Locking Subsidy Code
This command is applicable for all types of Subsidy Lock types:
• HPLMN only
• Type 1 HPLMN and 1 IMSI digit
• Type 2 HPLMN and 2 IMSI digits
• Type 3 HPLMN and GID 1
• Type 4 HPLMN and Range of IMSI digits
• Type 5 First SIM Inserted
• Type 6 First SIS Inserted (GID 1 or No action)
• Type 7 First SIM Inserted (GID 1 or Range Setting)
• Type 9 PLMN of first SIM Inserted
• D2 SIM Lock
• HPLMN that matches 1st SIM Inserted
• Valid PLMN
• Telefonica SIM Lock
• Airtel SIM Lock
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 +EMPC: 1,0 for set command.
