Phone Shield SIM908

I bought the new SIM908 shield and I cant find any material on the internet on how to use it with Arduino. Can anybody explain to me how to use it to send and recieve SMS and how to set it for various configurations through the jumper pins. Picture of the shield and the jumper pins attached.

Thank you.

Kind regards,
Hansel Omondi.

Which one have you got as the jumper strip doesn't match?

Anyway, download available at which does include example Arduino code in the folder named Code...
