2.5.3 Writing to the FDN Phonebook / FDN Replacement
Writing to the fixed-dialing number phonebook is protected by PIN2. A sample Write sequence (to e.g.
record 5) is provided below:
AT Command Comment

Input of PIN2
AT+CPBW=5,"1234",,”test”

PIN2 remains active as long as you use the commands
AT+CPIN, AT+CPBS, AT+CPBR, AT+CPBW, AT+CACM,
AT+CAMM, AT+CPUC or AT^SPIC, AT^SPBS, AT^SPBC,
AT^SPBG,:
If you use other commands or if none of the above commands
are executed within five minutes, PIN2 is no longer valid.
AT+CPBW=6,"5678",,”new test”
OK
A Write to record 6 is attempted...
In addition, if there is no FDN phonebook available on the SIM, it is possible to activate a feature
which activates an FDN-like behavior for the ”SM” and ”ME” phonebooks (FDN replacement).
(Currently this feature can only be activated via the MMI lock/device lock/excluding telephone book.)
In this case, the Write to the ”SM” and ”ME” phonebooks is ensured by the device code (PH-SIM PIN
and PH-SIM PUK, respectively).
The sequence for entering the device code is analogous to the above example.
