Welcome Note (Menu 4-5-5); Network Selection (Menu 4-5-6); Security Settings (Menu 4-6); Pin-Code Request (Menu 4-6-1) - Nokia 8850 User Manual

Within this menu you can store, erase, edit, send, and print via IR
the phone numbers assigned to your SIM card, if this is allowed by
the card.
The edits that you make here do not affect in any way the actual
subscriber number(s) of your SIM card.

Welcome note (Menu 4-5-5)

This menu allows you to set the message (up to 36 characters in
length) which is shown briefly when the phone is switched on.

Network selection (Menu 4-5-6)

The network to which you are connected can be selected either
automatically or manually.
Automatic
In mode the phone automatically selects one of the
cellular networks available in your area; the selected network can
be GSM900, GSM1800 or EGSM900.
Manual
In mode the phone shows a list of the available networks
and you can select the network you wish to use if this network has
a roaming agreement with your home network operator. If no such
agreement is in force, the text
must select another network. The phone stays in manual mode until
the automatic mode is selected or another SIM card is inserted into
the phone.

Security settings (Menu 4-6)

Your phone is equipped with a versatile security system to prevent
unauthorised use of the phone or the SIM card. See also 'Reference
Information' - 'Access Codes'.

PIN-code request (Menu 4-6-1)

Within this menu you can set the phone to ask for the PIN code of
your SIM card when the phone is switched on. You will need the PIN
code to turn this request function on.
Note that some SIM cards do not allow the PIN code request to be
turned off.
