Parameter Description

Phone security locks set by client or factory:

Primarily intended for the client to take safety precautions, passwords "SC" (SIM PIN) and "P2" (SIM PIN2) are

usually predefined, but can be configured individually. The password for lock facility "PS" may also be factory

set.

“SC“ SIM PIN. SIM requests password upon ME power-up and when this lock com-

mand is issued.

If incorrectly entered three times, the SIM PUK is required to perform authen-

tication. Input of the SIM PUK password is possible only with AT command

AT+CPIN or ATD. For further details please refer to chapter 5.1.1.

<password length>: 4 to 8 digits.

“PS“ 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". Accord-

ingly, the password may be called "phone code" or "device code". The "PS"

password is not associated with the PUK of the SIM card. It must be defined

before the first use of

<facility> "PS" with AT+CLCK.

<password length>: 4 digits.

If incorrectly entered three times, the Master Phone Code is required to lift the

lock. This Unblocking procedure is performed with

AT+CPWD using the follow-

ing parameters:

<facility>="PS", <old password>= Master Phone Code

(to be obtained from the module manufacturer), and

<new password>= the

new phone code ("PS" password for lock facility), if desired.

Mind that successful PIN authentication is a prerequisite for use of AT com-

mand

AT+CPWD. If Pin authentication has not been completed, input of the

Master Phone code password is possible only with AT command

AT+CPIN or

ATD. For further detail please refer to chapter 5.1.1.

Once the Master Phone Code has been acctepted, the mobile is operational,

and the "PS" lock is no longer active. If needed it must be set once again with

AT+CLCK.

“P2“ SIM PIN 2, e.g. required for authentication with facility lock "FD" (cf.

AT+CLCK).

If incorrectly entered three times, the SIM PUK 2 is required to perform authen-

tication. Input of the SIM PUK 2 password is possible only with AT command

AT+CPIN2 or ATD. For further detail please refer to chapter 5.1.1.

<password length>: 4 to 8 digits.

Factory defined SIM locks:

Typical examples of factory set SIM locks are prepaid phones or network locks, used to restrict the operation of

a mobile to a specific provider or operator. The client should be aware that each of these lock types can only be

unlocked if the associated password is available. For example, a mobile can be locked to accept only SIM cards

from the respective provider, or even one single SIM card. Once a different SIM card is inserted the ME will

prompt the client to enter a specific code. This is not the PUK of the SIM card, but usually an 8-digit code which

needs to be requested from the provider.

The locks can only be set by the manufacturer and need to be agreed upon between the parties concerned, e.g.

provider, operator, distributor etc. on the one side and the manufacturer on the other side. For details contact

your local dealer or Siemens AG.

“PF“ lock Phone to the very First SIM card

“PN“ Network Personalisation

“PU“ Network subset Personalisation
