Have you tried the command using Hyper Terminal? and also remember that not all mobiles implement the full CNMI command.... Have you tried different variations of the command?
I mean first try
at+cnmi=?

It should return something like
+CNMI: (0-2),(0-3),(0,2,3),(0-2),(0,1)

Then try different variations of the command.... like
AT+CNMI=2,0,0,1,0
AT+CNMI=2,0,0,0,0
AT+CNMI=1,2,0,1,0
etc.

and if it is not working then you can do a polling in your application.... After a fixed time interval you simply send
AT+CMGL=4 (When in PDU mode) or
AT+CMGL="ALL" (When in text mode)....
These commands will output all the SMS in the SIM.... You can test these commands in hyper terminal....

BTW according to the link
http://wiki.forum.nokia.com/index.php/AT_Commands
the CNMI command is implemented in NOKIA so you are most probably not being able to issue the right cnmi command...

How are you sending SMS? I mean are you in PDU mode i.e AT+CMGF=0 or in text mode i.e AT+CMGF=1?
and also are you using AT+CMGS command to send SMS?

I am sending sms through AT+CMGS command only.
In my software I use PDU mode (AT+CMGF=0) to send SMS.
In hyperterminal I tried in both modes. It can send sms. But not receiving at all.
I mean the same error message appears.
AT+CNMI?
ERROR
AT+CNMI=?
ERROR
etc..
Thanks in advance.

Can you read SMS using the AT+CMGR command?
you can read using the following syntax
AT+CMGR=1
where 1 denoted the memory location in the SIM you are trying to read.... Most SIMs will store 30 SMS in them so to read the 30th SMS you can use the command
AT+CMGR=30

Hi   Imarshad, I tried that also.
AT+CMGR?
ERROR
AT+CMGR=1
ERROR
AT+CMGR=2
ERROR

AT+CMGL?
ERROR
AT+CMGL=1
ERROR
AT+CMGL=4
ERROR
etc.,
But I can send sms. And I can change modes (PDU mode) AT+CMGF=0 or AT+CMGF=1.
What to do? Is there any way other than AT commands? or AT command itself having solution?
The same problem persists in Nokia 6085. My four customers had advised to buy Nokia 6085 mobiles by me. Now they bought it. I don't know what to tell them. This is extremely urgent Issue.
