Hi, We're working on an LPG gas detector.We're using a GSM module(SIM300,to alert the owner,of the gas leak) and arduino uno .We were trying to make a call to a phone using the module,but the process failed (as in,the commands appeared on the serial monitor with the delays but no call was received)…

GSM module,SIM300-code to make a call

Connections were made between the arduino board and the module.Can you please tell me,Why that's not a good idea and how else i can
make the connections?
