001-0004-829 Rev01Page 21 of 73What 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). +CMEERROR: 12 will prompt the client to unblock the SIM card by entering the associated PUK (= PINUnblocking Key / Personal Unblocking Key). After ten failed attempts to enter the PUK, the SIM cardwill be invalidated and no longer operable (the device will respond with: +CME ERROR: 770, whichstands for: SIM invalid - network reject). In such a case, the card needs to be replaced. PIN1consists of 4 to 8 digits, PUK1 is an 8-digit code only. To unblock a disabled PIN1 you have twooptions:• 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 varieswith the provider. PIN2 may either be a specific code supplied along with an associated PUK2, or adefault 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 PIN2authentification, but usually has no effect on PIN1. PIN2 consists of 4 digits, PUK2 is an 8-digit codeonly. 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#;.Phone lock:If the mobile was locked to a specific SIM card (= "PS" lock or phone lock), the PUK that came withthe SIM card cannot be used to remove the lock. After three failed attempts to enter the correctpassword, ME returns +CPIN: PH-SIM PUK (= response to read command AT+CPIN?), i.e. it is nowwaiting for the Master Phone Code. This is an 8-digit device code associated to the IMEI number ofthe mobile which can only by obtained from the manufacturer or provider. When needed, contactCinterion Wireless Modules GmbH and request the Master Phone Code of the specific module. Thereare two ways to enter the Master Phone code:• You can enter AT+CPIN=Master Phone Code• You can use the ATD command followed by the GSM code *#0003*Master Phone Code#;.Usually, the Master Phone Code will be supplied by mail or e-mail. If the received number isenclosed in the *# codes typically used for the ATD option, it is important to crop the preceding*#0003* characters and the appended #. Example: You may be given the string*#0003*12345678#. When prompted for the PH-SIM PUK simply enter 12345678. If incorrectlyinput, the Master Phone Code is governed by a specific timing algorithm: (n-1)*256 seconds (seetable below). The timing should be considered by system integrators when designing an individualMMI.Number of failed attempts Time to wait before next input is allowed1st failed attempt No time to wait2nd failed attempt 4 seconds3rd failed attempt 3 * 256 seconds4th failed attempt 4 * 256 seconds5th failed attempt 5 * 256 seconds6th failed attempt and so forth 6 * 256 seconds and so forth
