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...
