Hello!
I'm new to arduino and everything related to it! I'm trying to use a SIM900 shield with the arduino. You can see the code and the monitor in my picture. It responds with a bunch of numbers which makes no sense. I'm trying to read my sms storage. Can someone give me some insight in what i might be doing wrong?
This is the guide my seller provided

Best regards, Glutch
#include <SoftwareSerial.h>
SoftwareSerial Sim900Serial(2, 3);
void setup(){
Serial.begin(19200); // for serial monitor
Serial.println("Setup started");
Sim900Serial.begin(115200); // the GPRS baud rate
delay(2000);
Sim900Serial.println("AT+IPR=19200"); // Set the baud rate
delay(500);
Sim900Serial.begin(19200); // the GPRS baud rate
delay(1000);
Serial.println("Setup completed");
delay(1000);
Sim900Serial.print("AT+CPMS=\"SM\"\r");
delay(1000);
Sim900Serial.print("AT+CPMS=?");
}
void loop(){
//Sim900Serial.print("AT+CMGR=1\r");
//Sim900Serial.print("AT+CMGL=\"ALL\"");
if (Sim900Serial.available()){
Serial.println(Sim900Serial.read());
}
}
There you go! 
That had me confused too. But i'm just following the example provided
http://wiki.epalsite.com/index.php?title=SIM900_Quad-Band_GPRS_shield
#include <SoftwareSerial.h>
SoftwareSerial Sim900Serial(2, 3);
void setup()
{
Sim900Serial.begin(115200); // the GPRS baud rate
delay(2000);
Sim900Serial.println("AT+IPR=19200"); // Set the baud rate
delay(500);
Sim900Serial.begin(19200); // the GPRS baud rate
delay(1000);
}
void loop()
{
Sim900Serial.println("ATD***********;");//'*'instead the phone number you want to dial
while(1);
}
I'm following a guide that the seller provided when i bought the product. They do the same in every example. I'm new to arduino and c++. I know the basics of baud rate. What am i supposed to do?
The code assumes that the module is always set by default to 115200 bauds at starts, issues an AT command at the speed to change baud rate to 19200 and thus adjusts the baud rate to that new value afterwards
So question is does this match your hardware défaut ?

Im not sure, is there a way to check?
