Yes, several, although SMS is a better strategy today as far as I can 
tell.  Skytel (now Velocita Wireless) has a fine 2-way network, which we 
used until early last year.  We switched over to Metrotel, which had a 
smaller form-factor unit w/o 2-way which was better for us, for about a 
year.

However, we have completely cut over to SMS for alert pages now. 
Multitech makes a nice little GSM modem that sits on a serial port on 
your alerting systems.  I threw AT&T SIMs in them, wrote a tiny bit of 
glue to convert from email alerts to SMS alerts, and now we get all of 
our alerts using SMS.  There's lots of open source code to handle the 
modems.

It's completely out-of-band, even more so than our old 
touch-tone-phone-paging system was, so I'm actually happier with the 
total performance.  Given that GSM coverage is increasing while pager 
coverage seems static or decreasing, SMS via out-of-band GSM looks like 
a great solution.

Even situations like major power outages which would eventually take 
down cell towers w/o generators (or with malfunctioning generation) 
aren't a real concern because you usually have plenty of notice before 
the power goes all the way out...
