whenever a new SIM card is inserted into the phone.
Select Memory and the phone will ask for the security code whenever you
want to select the phone’s internal memory or to copy from one memory to
another. Note that the selected memory has to be the SIM card memory. See
Selecting the phone book settings on page 50 and Copying phone books on
page 54.
• Change of access codes and you can change security code, PIN code, PIN2 code
or barring password. Codes can only include numbers from 0 to 9.

such as 112, to prevent accidental dialling of an emergency number.
