Thankyou for ur advice on GSM module but i think i can easily get 6210/6310 nokia in my country, how do i test whether it supports AT commands?, will it be affected by the baud rate i set at 9600?

It does support the full AT commands from Nokia. you have to find that AT command manual though.

You will also need a specific cable from Nokia to RS-232.

When i connnect the phone to the PC and test the cable with hyperterminal, there is no response thats no ERROR or OK, what could be the problem,
I used the following commands at the hyperterminal,

AT
I expected OK or ERROR but its blank
AT+CPIN?
I expected +CPIN? READY OR ERROR but blank also

Could it be the cable?, PC or settings of PC, pliz guide me.

A million reasons!

Maybe the baud rate?
