Nokia 3110 classic - Access Codes

• PIN code request and UPIN code request — to set the device to ask for
your PIN or UPIN code every time the device is switched on. Some SIM cards
do not allow the code request to be turned off.
• PIN2 code request — to select whether the PIN2 code is required when
using a specific device feature which is protected by the PIN2 code. Some
SIM cards do not allow the code request to be turned off.
• Call barring service — to restrict incoming calls to and outgoing calls from
your device (network service). A barring password is required.
• Fixed dialling — to restrict your outgoing calls to selected phone numbers
if this function is supported by your SIM card. 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 must be included in the fixed dialing list.
• Closed user group — to specify a group of people whom you can call and
who can call you (network service)
• Security level — Select Phone to set the device to ask for the security code
whenever a new SIM card is inserted into the device. If you select Memory,
the device asks for the security code when the SIM card memory is selected,
and you want to change the memory in use.

or barring password
