We use a standard modem and pestered Alltel until they gave us the 
secret TAP gateway number.

Nagios is configured to use sms_client:  http://www.smsclient.org/

Works great other than being a royal pain in the rear when a lot of 
things go down and dependencies are not set up in Nagios... I'll fix 
that one of these days :-)
