5.7AT^SPWD Change Password

The AT^SPWD command provides the same functions as AT+CPWD. The major difference between both com- mands is that, apart from the different prefixes "^SPWD" and "+CPWD", the AT^SPWD command includes addi- tional functions dedicated to the Customer SIM Lock. Please note that this feature is only supported by specifically pre-configured MC55 modules and, therefore, not part of the standard "MC55 AT Command Set". Ordering information and a detailed description of the "Customer SIM Lock" feature can be requested from Sie- mens. All other functions and parameters of AT^SPWD are described in Section 5.6, AT+CPWD.

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 for more detail on the various lock features.
