I remember that I had the same problem working on a mobile phone.

I think most of them don't support this , here is a link http://www.developershome.com/sms/ch...andSupport.asp

Not sure but try this AT+CNMI=? it should show you if the command is supported.
I am using an industrial GSM modem and it returns:

+CNMI : (0-3)(0 -3)(0,2)(0-2)(0,1)

If your mobile phone supports it then try the fallowing sequence of commands:

ATZ
AT+CMGF=1
AT+CNMI=2,1

Hope it helps,

I didn't try this in Java , but I have an old sample to exaplin the concept:

This is written in Delphi:

procedure TForm1.SendSMS(tel,mesaj:string);   
begin
ComPort1.Writestr('ATZ'+chr(13)); // reset device
delay(1000);
ComPort1.Writestr('AT+CMGF=1'+chr(13)); //  operate in SMS text mode.
delay(1000);
ComPort1.Writestr('AT+CMGS="'+tel+'"'+chr(13));
delay(1000);
ComPort1.Writestr(mesaj + chr(26)); // character with ascii code 26
delay(3000);
end;

There must be a serial port component in Java and the code would look similar.

The reason why I put a delay there is because it takes a while to execute the command , normally this is not the correct way to do it but it works.
The best way to do it is to have a handler , that reads the data received from the mobile phone.

When you send ATZ you have to wait to receive an OK and only after that send the next instruction AT+CMGF=1 , and so on...

Try just to send an SMS for now, and then try to implement the receive SMS feature.

If you try to code it in C sharp I could help you faster with concrete sample code , I am currently working on something very similar in C sharp.
All the best,
