This is a very simple way to interface Q2303 or similar wavecom module with Arduino. Connect Tx of Modem with Arduino Rx and Rx of Modem with Arduino Tx pin (Software Rx, Tx). Power up Modem with Adapter(5V, 1A). Insert SIM. Make sure modem switch is on. Modem GND must be connected with Arduino GND. I draw a picture for Interfacing with Arduino. I tested it. Code is below.

}

void loop()
{

//add our message to the CellContent string
  cellContent+=content;
//add the Crtl-Z hex character 
  cellContent+=ctlZ;
//put the modem into text mode 
  textMode();

  cell.print(r);
}

void sendMsg(){
//This number needs to be replaced with the number you are sending to 
  cell.print("AT+CMGS=\"01717973140\"");
  cell.print(r);
  cell.print(cellContent);
  cell.print(r);
