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

Nothing is happening when i send AT command from Arduino, please guide me on what needs to be done.
Thanks,
Anil
