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.
Parameter is not applicable to SIM locks.
and instructions for unlocking must be obtained from the network provider.
