What To Do If Pin Or Password Authentication Fails - Multi-Tech MultiModem EDGE Reference Manual

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 Multi-Tech wireless modem 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.

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 (see Table above).
Call Barring:
Supported modes are "AO", "OI", "OX", "AI", "IR", "AB", "AG", "AC". If the call barring password is entered incorrectly
three times, the client will need to contact the service provider to obtain a new one.
