5.7AT^SPWD Change Password

The AT^SPWD command comprises all functions of the AT+CPWD command. Apart from the different prefixes "^SPWD" and "+CPWD", the major difference is that the <facility> list of AT^SPWD includes the additional "CM" password dedicated to the Customer SIM Lock. Set with the command AT^SCSL, this type of lock allows the application manufacturer to lock a mobile to specific operators.

The Customer SIM Lock feature is designed to be configurable during the production of the mobile application. Therefore, to program the "CM" password, the AT^SPWD write command can be used no matter whether the SIM is inserted or PIN authentication has been done. Opposite to that, passwords for all other facilities can only be edited if the SIM is present and PIN authentication completed.

IMPORTANT: Please note that, even though there is no need for a factory set Customer SIM Lock, you are strongly advised to specify at least a "CM" password, avoiding that end users ever have a chance to activate this lock type.

Each password is a string of digits the length of which varies with the associated facility. The test command returns a list of pairs which represent the available facilities and the maximum length of the associated password.

See also AT commands AT+CLCK and AT^SLCK as well as AT^SCSL for more detail on the various lock features.
