Parameter Description
“CM“ Password used as Customer Mastercode for Customer SIM Lock.
Defining the "CM" password allows the application manufacturer to set a Cus-
tomer 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=<facil-
ity>,<old password>. Please note that this action will delete all personali-
sation data programmed by the manufacturer with AT^SCSL (including the
operator list).
A description of all other passwords commonly supported by AT+CPWD and AT^SPWD can be found in Section
5.6, AT+CPWD. The "CM" password cannot be edited with AT+CPWD.
Notes
• When changing the PIN2 (<facility>="P2") it is recommended to check the new state of PIN2 using the
AT+CPIN2 command.
• In the airplane mode the write command version for the network related <facility> (AO, OI, OX, AI, IR,
AB, AG and AC) is not supported. For remaining facilities the command is fully functional then.
