Notes
• Caution: After entering a password with 
 all other commands that need access to data on the SIM
card may be blocked for up to 20 seconds!
• 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
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.
ME offers various options to verify the present status of network registration: For example, the 
 com-
mand indicates the currently used network. With 
 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).
• Wait 10 seconds after PIN input before using SMS related commands.
 and 
 can also be entered in quotation marks (e.g. "1234").
• To check the number of remaining attempts to enter the passwords use the 
 command.
• See 
 for information on passwords.
• See 
 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 oper-
able. 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 
=PUK1,new PIN1.
• You can use th
 command followed by the GSM code **05*PUK*newPIN*newPIN#;.
PIN2 / PUK2: 
PIN2 prevents unauthorized access to the features listed in 
. The handling of PIN2 varies with the pro-
vider. 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 per-
manently block the additional features subject to PIN2 authentification, 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 
=PUK2,new PIN2.
• You can use th
 command followed by the GSM code **052*PUK2*newPIN2*newPIN2#;.
Phone lock: 
If the mobile was locked to a specific SIM card (= "PS" lock or phone lock), the PUK that came with the SIM card
cannot be used to remove the lock. After three failed attempts to enter the correct password, ME returns +CPIN:
PH-SIM PUK (= response to read comman
?), i.e. it is now waiting for the Master Phone Code. This
