change the "PS" password): use the master phone code.

CAUTION:
THE INDIVIDUAL ME USED IS DEFINITELY AVAILABLE! Otherwise, the module used will be rendered useless

5.7 AT^SPWD Change Password

The AT^SPWD command comprises all functions of the AT+CPWD command. Apart from the
Description:
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. However, at this time customer SIM locks are not supported.
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 for more detail on the various lock features.

Password used as Customer Mastercode for Customer SIM Lock.
Defining the "CM" password allows the application manufacturer to set a Customer SIM
Lock by activating a Network Personalization ("PN") with the AT^SCSL command. The
"CM" password is mandatory for each operation with AT^SCSL.
<password length> of "CM": 8 digits.
To delete the "CM" password use the following syntax: AT^SPWD=<facility>,<old
password>. Please note that this action will delete all personalization data programmed by
the manufacturer with AT^SCSL (including the operator list).
