These GSM modems use the AT command set thru their serial port You have to connect the USART of the PIC to the GSM modem
in a loop:
- use the AT command set language to poll for any SMS arrived ('AT+CMGL' command)
- look for a specific text (password) in the SMS (if yes:activate the relay for 500ms and release it)
- delete all incoming SMS
