yes i have checked the modem with hyperterminal, manually by  typing following code …

 

  AT+CMGF=1  response “OK” was returned.

  AT+CMGS=”9030888888″.  response “>” was returned.

  Then I typed my message, after that I Pressed Cltr+Z to send the message and it was sucessfull 

But when i have dumped the code into Microcontroller then its not sending SMS ….!!!
