“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 Section 5.1.1, What to do if PIN or pass-
word authentication fails?.
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and the "PS" lock is no longer active.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 Section 5.1.1, What to do
if PIN or password authentication fails?.
<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.

Supplementary Service Call Barring:Supplementary Service "Call Barring" allows to specify conditions under which calls will be disallowed by the
network.
The availability of the Supplementary Services varies with the network. To benefit from call barring the client will
need to subscribe them, though a limited number of call barring types may be included in the basic tariff pack-
age.
<password length>: The Network Password needs to be supplied from the network provider or network oper-
ator. Usually there is one 4 digit password which applies to all call barring options. For details contact your pro-
vider.
