Phase 2 includes SIM cards with an FDN phonebook. You can activate a block on the
card in order to restrict the telephone numbers that can be called to those contained
in this directory. To modify these entries, you must enter PIN2 with the aid of the
AT+CPIN2 command. All entries are similar to those for the AT+CPIN command. This
command is accepted only if the card also supports this functionality.

Please note: PIN2 protects the FDN phonebook. In order to modify the FDN phonebook
by means of the AT+CPBW=... command, you must first enter PIN2. If you have not yet
done so, an error message is returned. After entering PIN2, you can read or write any
number of directory entries without having to enter PIN2 each time. As soon as you use
a command that is not related to the phonebook, PIN2 is “forgotten”

. It is also forgotten

if you do not access the phonebook for a period of 5 minutes.
