Can the SIM5216A do this?

Is it possible for the SIM5216A to do the following with the right AT command script?: (Basically it will be used with an Uno R3 to act as a "remote switch") When the "remote switch" receives a SMS text "ON", the digital output goes high, then sends an SMS text "Confirmed ON". When the "remote switch" receives a SMS text "OFF", the digital output goes low, then sends an SMS text "Confirmed OFF". Notes: I want ANY phone to operate device and not have to set up "authorized phone numbers" Digital output will run a 12vdc 100ma micro pump (or similar). Cellular signal strength should be able to be checked by sending SMS text "signal" and receive a response (or similar method). Is it difficult to write this? Thanks, Jim
