I have a SIM300 GSM/GPRS module and i made the following steps to interface with Arduino UNO:
1) Connect TX pin of SIM300 to PIN6 on Arduino
2) Connect RX pin of SIM300 to PIN7 on Arduino
3) Connect Ground of Arduino with Ground of Sim300.
I am using the following code where NewSoftSerial.h is replaced by SoftwareSerial.h:
