Chapter 5 – Security Commands
Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 86
Notes:
• When changing the PIN2 (<facility>="P2") it is recommended to check the new state of PIN2 using the
AT+CPIN2 command. In fact, this command is available after PIN2 authentication. See +CPIN2.
• Usage of the PIN is dependent on conditions specified for the command. Not all command types are PIN
protected (for example a write command can be PIN protected while the read command is not).
Note: The table provided in Section 21.3, Available AT Commands and Dependency on SIM PIN uses the
same symbols.
• In airplane mode, not all described functions are available. For example, the test or read command is
usable, the write or execute command may not. Furthermore, only some of the listed parameters can be
changed in airplane mode. A typical example is AT^SCFG that controls different features. Specifically, in
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.
Examples
Example 1 – To specify the "CM" password required as Customer Mastercode for the Customer SIM Lock:
AT^SPWD="CM" Check if the Customer Mastercode was already set.
ERROR No, it was not.
AT^SPWD="CM", ,"12345678" Specify a new Customer Mastercode (where <old password> is omitted
and <new password>"12345678" = new Customer Mastercode)
OK The Customer Mastercode has been set to "12345678".
AT^SPWD="CM" Checking again.
OK Yes, it is active now.
Example 2 – To change the Customer Mastercode:
AT^SPWD="CM","12345678","44444444" (where "12345678" = old Customer Mastercode, and "44444444" = new
Customer Mastercode).
OK The Customer Mastercode has been changed from "12345678" to
"44444444".
EXAMPLE 3 – To delete the Customer Mastercode:
AT^SPWD="CM","44444444" Delete the Customer Mastercode by omitting <new password> and entering
only the <old password> "44444444".
OK The Customer Mastercode as well as all personalization data programmed
by the manufacturer with AT^SCSL were deleted.
