SMS Module Inquiry

Anyone here use the SMS module to receive text messages and do something with that received message? I am looking into purchasing the SMS module and was curious what was being with it. I see that I would need the Alarm Notification module (I have it already) and that I would need an Airlink RV50 series hardware and a SIM card for it.

I dont think you can do anything other than acknowledge alarms using the sms module. not sure what you had in mind. someone correct me if I am wrong.
