I am not sure why you suggest not using sms. If the Internet goes down - the monitoring program cannot email you! So from where I am standing, SMS makes sense!
We had it sending SMS messages and e-mail for some time but switched to just e-mail because SMS has a limit for the number of characters used in the message. Second issue we had was that we did not have the budget at that time to get an internal modem that used a SIM card just like a mobile phone and the same thing as a USB dongle were not that common and useable yet ( 
must have been in the stone age. Time flies .... 
) so we hooked up a mobile phone with a USB data cable. It worked but there was lots of room for improvement. It is also just a matter of personal preferences and the requirements of the client I guess. For us the e-mail notifications are enough.
