The Quectel M95FA GSM/GPRS shield cannot be used with the Arduino Uno without some (easy, but neccessary) hardware modifications.

After applying the neccessary hardware modifications you can finally send (multiple) SMS messages using the SOS Quectel M95FA GSM/GPRS shield with Arduino Uno. All modifications are clearly explained in the PDF file.
The zip-file contains the Arduino sketch to be used with the described configuration.
