+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 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.
