Result code +CPBS: “MD“ , “SM“ , “OW“ , “FD“
Meaning
MD Last number redial memory; displays the last telephone num-
bers that you dialed.
SM SIM card; this is the standard phonebook containing the
entries.
OW Own telephone number; this phonebook contains your own
telephone numbers under which you can be reached. Nor-
mally, you only need to read this directory since you cannot
call your own number and it does not change.
FD Fixed dialing number; this is a second phonebook. If the rele-
vant block is set, only the numbers from this FDN phonebook
can be called. This phonebook and the block are protected by
PIN2.
