Hi Grogs.
Try this link. I've used these with our Building Automation Systems. Works well.

You can send text messages via serial and AT commands,
trigger preset messages with digital inputs,
escalate to the next number should the party not respond,
etc.
Very versatile little unit and well priced.
Download the manual and see if it suits your purposes.
Regards,
Mike B.
