When
security features that restrict calls are in use
(call barring, closed user group and fixed dialing),
calls may be possible to certain emergency numbers
in some networks.
To
adjust the security settings of your Nokia 7250i, press
Menu, select Settings and Security
settings.
Select:
PIN code request to set the phone to ask
for your PIN code every time the phone is switched
on. Some SIM cards do not allow the PIN code request
to be turned off.
Call barring service (network service) to
restrict incoming calls to and outgoing calls from
your phone. A barring password is required.
Fixed dialing to restrict your outgoing calls
to selected phone numbers if this function is supported
by your SIM card. The PIN2 code is required.
When the fixed dialing is on, GPRS connections are
not possible except while sending text messages over
a GPRS connection. In this case, the recipient’s
phone number and the message center number have to
be included on the fixed dialing list.
Closed user group. Closed user group is a
network service that specifies the group of people
whom you can call and who can call you. For more information,
contact your network operator or service provider.
Security level. Select Phone and
the phone will ask for the security code whenever
a new SIM card is inserted into the phone.
Select Memory and the phone will ask for
the security code when the SIM card’s memory
is selected and you want to change the memory in use,
or you want to copy from one memory to another.
Access codes to change the security code,
PIN code, PIN2 code or barring password. Codes can
only include numbers from 0 to 9.
