Hello Marco,
I am happy you made it work! What was the problem? Regards

Palliser, for the byte error = Wire.endTransmission(); , I got nothing, everytime when comes to Wire.endTransmission(); will just stuck there, also the Scanner return nothing.

I wanted you to print the error like....

Code:
byte error = Wire.endTransmission();
Serial.println(error);

What do you get? 1,2,3 or 4?

Hello gybmage,

Could you also tell what WireEndTransmission error are you getting? I mean...

Code:
byte error = Wire.endTransmission();

I recommend you to visit the Visual Micro forum.

In the code I sent you, can you change in the serial monitor (not in the code) the baud rate to 19200 and run it again?
Anyway, I am far from my lab where I have my GSM shield but tonight (US central time) I can run some tests for you.

Thanks,

The example should work thoroughly. Anyway, there is another way to test if the modem is working OK.
Here a code you can load into the Arduino UNO and then from the serial monitor of the Arduino IDE, you can
type/send for example AT, then the modem should answer with an OK. If that work, then
you can manually dial a number to your phone like ATD[phone number]; and so on.

Code:
#include <SoftwareSerial.h>
 
SoftwareSerial mySerial(2,3);
 
void setup()
{
  mySerial.begin(19200);
  Serial.begin(19200);
}
 
void loop()
{
  if (mySerial.available())
    Serial.write(mySerial.read());
  if (Serial.available())
    mySerial.write(Serial.read());   
}

As far as I can see, the LEDs status of your GSM shield is OK. Are you using the external power adapter? If not, the only thing is for you to connect the Arduino with the external power supply and see.

What about the NET and STATUS LEDs?

Marco,
The USB power is not enough. You have to connect the Arduino UNO with an external power supply adapter that can provide up to 700 to 1000 mA. Did you press the power button? LED status?

(Alimentar el Arduino UNO solo con el cable USB no es suficiente. Necesitas conectar tambien al Arduino UNO un adaptador de 5 a 12 voltios que pueda proveer hasta 1 Amperio. Quisiera saber si presionaste por algunos segundos el boton que dice "POWER" en el escudo GSM. Como estan los LEDs?

What do you mean with no power?


Without power, rotate the fan blades  using your fingers or a stick in both directions while monitors the direction pin to determine the correspondent output values.

The arduino GSM shield needs to be power up (ON). In order to do that you have to press the power button. How is the status of the LEDs?

Remember also that the GSM shield requires  an external power supply that can provide between 700mA and 1000mA.

Did you power up the modem (pressing the power button for a couple of seconds)?
I also recommend you to move your post to the Arduino GSM topic:

http://forum.arduino.cc/index.php?board=90.0

You can start with the SenSMS example in the Arduino IDE.

File->Examples->GSM->SendSMS

Hola Timoteo,
Is your small turbine magnetized? If so, try to rotate the turbine manually (in both directions) very slowly (with no power) and see how the direction pin changes between LOW and HIGH. Saludos,
