Problem using the GSM shield 900

I need help with the arduino sim 900 shield,I have tried all the possible connections and I codes I only get infinite question marks or unreadable characters in the serial monitor. I am in Ghana,can anyone help me?

post your sketch here ,

post up a drawing/image showing how you connected the shield ( not fritzing diagrams)

Hi, do you have the Arduino board separated from the SIM 900 board ? I am in Argentine. Best regards.

The idea is to test the SIM 900 board first with AT commands directly from the PC trought serial port (without Arduino). In this way you could confirm 100 % that the the SIM is OK.
