In the dark days before cell phones, when alpha-numeric pagers were big, a company I worked for converted from over 20 pager companies to AT&T (prior to SWBell purchase of AT&T). We used SMS message by using a modem to dial their SMS gateway from our Sun servers. It was highly reliable then. We used it for out of band alerting. One of the neat tricks was we could send the same message to many people atonce, but only one message per phone call to the SMS server.
The biggest problem with these is that more and more carriers have dropped TAP support. For example, we cannot send messages to anyone with a T-Mobile or AT&T phone any longer, unless we use e-mail (which somewhat defeats the purpose when we're paging from a monitoring system).
