Phone Security Locks Set by Client
PH-SIM PIN ME is waiting for phone-to-SIM card password if “PS” lock is active and the
client inserts other SIM card than the one used for the lock. (“PS” lock is also
referred to as phone or antitheft lock).
PH-SIM PUK ME is waiting for Master Phone Code, if the above “PS” lock password was
incorrectly entered three times.
PH-FSIM PIN ME is waiting for phone-to-very-first-SIM card. Necessary when “PF” lock
was set. When powered up the first time, ME locks itself to the first SIM card
put into the card holder. As a result, operation of the mobile is restricted to
this one SIM card (unless the PH-FSIM PUK is used as described below).
PH-FSIM PUK ME is waiting for phone-to-very-first-SIM card unblocking password to be
given. Necessary when “PF” lock is active and other than first SIM card is
inserted.
PH-NET PUK ME is waiting for network personalization unblocking password.
PH-NS PIN ME is waiting for network subset personalization password.
PH-NS PUK ME is waiting for network subset unblocking password.
PH-SP PIN ME is waiting for service provider personalization password.
PH-SP PUK ME is waiting for service provider personalization unblocking password.
PH-C PIN ME is waiting for corporate personalization password.
PH-C PUK ME is waiting for corporate personalization un-blocking password.
Notes:
• Successful PIN authentication only confirms that the entered PIN was recognized and correct. The output of
the result code OK does not necessarily imply that the mobile is registered to the desired network.
Typical example: PIN was entered and accepted with OK, but the ME fails to register to the network. This
may be due to missing network coverage, denied network access with currently used SIM card, no valid
roaming agreement between home network and currently available operators etc.
The device offers various options to verify the present status of network registration: For example, the
AT+COPS command indicates the currently used network. With AT+CREG you can also check the current
status and activate an unsolicited result code which appears whenever the status of the network registration
changes (e.g., when the ME is powered up, or when the network cell changes).
• <pin> and <new pin> can also be entered in quotation marks (e.g., “1234”).
• To check the number of remaining attempts to enter the passwords use the AT^SPIC command.
• See AT+CPWD and AT^SPWD for information on passwords.
• See AT+CLCK and AT^SLCK for information on lock types.
• This command is PIN protected.
• This command is supported in airplane mode.
5.1.1 What to Do if PIN or Password Authentication Fails?
PIN1 / PUK1:
After three failures to enter PIN 1, the SIM card is blocked (except for emergency calls). +CME ERROR: 12 will
prompt the client to unblock the SIM card by entering the associated PUK (= PIN Unblocking Key / Personal
Unblocking Key). After ten failed attempts to enter the PUK, the SIM card will be invalidated and no longer
operable.
In such a case, the card needs to be replaced. PIN1 consists of 4 to 8 digits, PUK1 is an 8-digit code only.
To unblock a disabled PIN1 you have two options:
• You can enter AT+CPIN=PUK1,new PIN1.
• You can use the ATD command followed by the GSM code **05*PUK*newPIN*newPIN#;.
PIN2 / PUK2:
PIN2 prevents unauthorized access to the features listed in AT+CPIN2. The handling of PIN2 varies with the
provider.
PIN2 may either be a specific code supplied along with an associated PUK2, or a default code such as 0000. In
either case, the client is advised to replace it with an individual code. Incorrect input of PUK2 will permanently
block the additional features subject to PIN2 authentication, but usually has no effect on PIN1. PIN2 consists of 4
digits, PUK2 is an 8-digit code only.
To unblock a disabled PIN2 you have two options:
• You can enter AT+CPIN2=PUK2,new PIN2.
• You can use the ATD command followed by the GSM code **052*PUK2*newPIN2*newPIN2#;.
SIM Locks:
These are factory set locks, such as “PF”, “PN”, “PU”, “PP”, “PC”. An 8-digit unlocking code is required to
operate the mobile with a different SIM card, or to lift the lock. The code can only be obtained from the provider.
Failure to enter the password is subject to the same timing algorithm as the Master Phone Code.
