Changing the phone code
You define the phone code 
(4-8 digits) when you call up a 
phone-code protected function for 
the first time (see page 14). It is then 
valid for all phone-code protected 
functions.
If you fail to enter the correct 
PIN number for the third time, ac-
cess to the phone code and the func-
tions that use it is denied. If this oc-
curs, contact the Siemens Service 
Clearing SIM card barring
If the PIN is entered incorrectly three 
times, the SIM card is barred. Enter 
the PUK (MASTER PIN) provided by 
your service provider with the 
SIM card in accordance with the 
instructions.
If the PUK (MASTER PIN) has been 
lost, please contact your service 
provider.
Preventing accidental 
activation
Even if PIN use is deactivated, confir-
mation is required to switch on the 
phone.
This prevents accidental activation 
of the phone, e.g. when you are car-
rying it in a bag or when you are trav-
elling in an aircraft.
