problem receiving a message, gsm/gprs module a6 (elecrow)

i have a problem like that:

code:

Serial3.print(“AT+CMGF=1\r”); // Configuring TEXT mode
delay(100);
updateSerial();
Serial3.print(“AT+CSDH=1\r”); // mostrar la informacion del mensaje
delay(100);
updateSerial();
Serial3.print(“AT+CNMI=1,2,0,0,0\r”); // Decides how newly arrived SMS messages should be handled
delay(200);
updateSerial();

but when a receive the message, i just receive the data, i need the information of the remote number.
