I have Growl installed and I'm using it with RSS Growler. I successfully get notifications from RSS Growler on my mac, but now I want to set it up so that I get those notifications on my phone (ideally via sms). However, whenever I select "sms" as the action for a notification, I simply hear a system ding. I've tried searching, but I can't find any guide or information on how to set up sms notifications. Could someone please point me in the right direction.
