There are a lot of pager networks here that I've seen for myself which are used by hospitals, and they're constantly transmitting sensitive and personally-identified medical information in clear text. It's really not good.
With the notification system used by my phone company the only thing transmitted is a short numeric code, not even a phone number, just a handful of digits that I recognize as meaning someone left a message. No otherwise identifiable information.
