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.
When you attempt to set a
<facility>
or
<class>
which is not provisioned, not yet subscribed to, or not sup-
ported by the module, the setting will not take effect regardless of the response returned. The responses in these
cases vary with the network (for example "OK", "+CME ERROR: Operation not allowed", "+CME ERROR: Oper-
ation not supported" etc.). To make sure check the extended error response with
AT+CEER
and the lock status
with
<mode>
=2.
<password>
: Network password supplied from the provider or operator. Usually there is one password which
applies to all call barring options. For details contact your provider.
