GSM module,SIM300-code to make a call

hey,
So i tried connecting pins 10 and 11 to the tx and rx of the module and uploaded the following code..Still, no action. I think i might be missing a major point ,conceptually or in the code..so, could really use some help now ,although i know this is like, the 5th question on the same topic,sorry 'bout that :-p
Here's the code..
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10,11);
void setup()
{
mySerial.begin(9600); // the GPRS baud rate
delay(2000);
mySerial.println("AT");
delay(2000);
mySerial.println("AT+CSMP=17,167,0,0");
delay(2000);
}
void loop()
{
mySerial.println("AT+CMGF=1"); // set the SMS mode to text
delay(2500);
mySerial.write("AT+CMGS=");
mySerial.write(34); //ASCII of “
mySerial.write("+91xxxxxxxxxx");
mySerial.write(34);
mySerial.write(13);
mySerial.write(10);
delay(2500);
mySerial.println("hello"); //this is the message to be sent
delay(2500);
mySerial.write(26);
mySerial.write(13);
mySerial.write(10);//Ascii code of ctrl+z to send the message
delay(2500);
while(1);
}
..Thanks in advance!
