Alternatively, you can make use of mackers o2sms script, and a little
perl.
I've got this working at home and find it very handy. My setup is a small
linux box connected to the bb modem (an eircom netopia jobby), which is up
24/7. A small perl script scrapes the netopia's webadmin page and checks
the ip address for the external interface. It then sends this to me via
sms using o2sms if it changes.

I find it works remarkably well.
