Unintended consequences can really get you with this one.  Cell phone
networks are often the first telecom technology to get overloaded (or
in some cases just fail completely) in an emergency.  Start sending
out text messages to everyone, and you're likely to trigger
thousands or millions of immediate call attempts by users trying
to reach family members, etc.  Boom -- saturation, and the really
important emergency calls don't get through.

Most people don't realize how limited cell phone capacity really is,
relatively.  Of course, the cell carriers don't exactly promote
their limitations.
