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)…
