I sent a AT Command [AT+CLCK="AO",1,"1234"] , but it always failed and
gave a CME ERROR 30 . I sent [AT+CLCK="AO",2], it gave [+CLCK: 1,1]
indication. Why?
(I's using wavecom GSM/GPRS Q2406B modem),

Maybe your carrier does not support it.  It would be a network level
feature.

Agreed.  The "+CME ERROR: 30" result means "no network service"
(GSM 07.07).

An interesting observation on command syntax:

GSM 07.07 agrees with your syntax

       AT+CLCK="AO",1,"1234"

whereas the Wavecom "AT Commands Interface Guide" gives the
syntax as:

       AT+CLCK="AO",1,1234

ie, no quotes around the PIN.

tks.
Antoher question: which style is recommended by GSM 07.07, "1234" or
1234?

This example is given in GSM 07.07:

       AT+CLCK="OI",2
       +CLCK: 0,7
       OK
       AT+CLCK="OI",1,"1234"
       OK
       AT+CPWD="SC","4321","1234"
       OK
