Chapter 4 – Serial Interface Control Commands Example 3 This example shows that after successful SIM PIN1 authentication the counter of the AT^SPIC execute and read command refers to SIM PIN2; i.e., it does not reflect the status of SIM PIN1. This may be a problem if the user enters a wrong PIN1 and is not aware that the number of attempts left to enter SIM PIN1 is counted down. +CREG: 0 at+cpin=1234 OK +CREG: 2 +CREG: 1 at+cpin +CPIN: READY at^spic ^SPIC: 3 OK AT^SPIC ^SPIC: SIM PIN2 OK at+clck=”SC”,0,456789 CME ERROR: incorrect password at^spic ^SPIC: 3 at+clck=”SC”,0,456789 CME ERROR: incorrect password at^spic ^SPIC: 3 at+clck=”SC”,0,456789 CME ERROR: incorrect password +CREG: 0 at^spic ^SPIC: 10 The mobile ist properly registered to the network. The AT+CPIN read command confirms that SIM PIN1 authentication was successful. As SIM PIN1 authentication was successful, the counter relates to SIM PIN2 and correctly indicates that the user has 3 attempts to enter SIM PIN2. Likewise, the read command notifies that the ME is waiting for SIM PIN2. First attempt to enter a wrong SIM PIN1. SIM PIN1 authentication is still valid, and the counter relates to SIM PIN2. Second attempt to enter a wrong SIM PIN1. SIM PIN1 authentication is still valid, and the counter relates to SIM PIN2. Third attempt to enter a wrong SIM PIN1. SIM PIN1 authentication is no longer valid. This time, after the SIM PIN1 code has been disabled, the counter indicates the status of SIM PIN1 and notifies that 10 attempts are left to enter the SIM PUK. To avoid conflicts we recommend to use the AT^SPIC read and write commands rather than the execute command only. The read command clearly states the currently required password, and the write command may be used to get the counter for a specific , in this case for example “P2”. Multi-Tech Systems, Inc.

5.4 AT+CLCK Facility Lock Chapter 4 – Serial Interface Control Commands Description: AT+CLCK can be used to lock, unlock or interrogate a network or ME . The command can be aborted when network facilities are being set or interrogated. Test Command Syntax: AT+CLCK= Response(s): +CLCK:list of supported s, OK Write Command Syntax: AT+CLCK=, [, ][, ] Response: If is not equal 2 and command successful: OK if = 2 and command successful: +CLCK: [, ] [+CLCK: [, ]] [+CLCK: ...] OK If error is related to ME functionality +CME ERROR Parameter Descriptions: Phone security locks set by client or factory Primarily intended for the client to take safety precautions, “SC”, “PS” and “FD” can be configured individually. Parameter is not applicable to security locks. See examples below for further details. “SC“ “PS“ “FD“ SIM (lock SIM cards). SIM requests password upon ME power-up and when this lock command is issued. : SIM PIN1. Phone locked to SIM card. ME requests password when other than current SIM card is inserted. “PS” lock is frequently referred to as “phone lock”, or “device lock”. Accordingly, the password may be called “phone code” or “device code”. The “PS” password is not associated with the PUK of the SIM card. If incorrectly entered three times, the Master Phone Code is required to lift the lock. This is an 8-digit device code associated to the IMEI number of the mobile which can only by obtained from the manufacturer of the module. Once the Master Phone Code has been accepted, the mobile is operational, and the “PS” lock is no longer active. If needed it must be set once again. Important Note: Multi-Tech does not lock SIM Cards. : User defined password. It is needed before the first use of “PS” and, therefore, must first be specified with AT+CPWD or AT^SPWD, if it has not been predefined by factory settings. If set by factory (e.g., for a prepaid mobile), the password is supplied by the provider or operator. SIM fixed dialing memory: If the mobile is locked to “FD”, only the phone numbers stored to the “FD” memory can be dialled. (Capacity of FD phonebook depending on the SIM card). : SIM PIN 2. If a lock on the SIM fixed dialing memory is active, the following applies: • Outgoing voice, data or fax calls can be made only to numbers stored in “FD” phonebook. Result code depends on the type of the call: for voice calls, indication is “+CME Error 257: Call barred”. for data and fax calls, indication is “NO CARRIER”. • Access to defined Supplementary Services such as Call barring, Call waiting, Call forwarding, Call hold and Multiparty is possible only if the exact corresponding public MMI *# code for the desired service is stored in the fixed dialing number phone book and used with ATD. AT commands for supplementary service control are barred while “FD” lock is active. Indication is “+CME Error 257: Call barred”. • Access to Unstructured Supplementary Services (‘USSD) is possible only if the exact desired USSD string is stored in the fixed dialing number phone book and used with ATD. AT commands for USSD are barred while “FD” lock is active. Indication is “+CME Error 257: Call barred”. • SMS can be sent only to phone numbers which are stored in the “fixed dialing numbers” phonebook “FD”. Also, a valid Service Center Address (international format) must be present in “FD” to allow sending SMS at all. Indication is “+CMS Error 302: operation not allowed”. • GPRS commands can be used only if the “fixed dialing numbers” phonebook “FD” contains an entry with phone number “*99#”. This single entry enables all GPRS commands, including AT commands and modem compatibility commands like “ATD*99***1#” or “ATD*98***1#”. Indication is “+CME Error 257: Call barred”.
