Cell Phone Texting help!!!?

So The Veronicas, my FAVORITE BAND IN THE WORLD, put a video out telling us that if we want them to tour in our city here in the states, to text the word VERONICAS to 50505. Now, I don't know exactly how to do that. You also have to include your location. Do I just put "50505" in the "To:" part of the text? And that's it for the number part? And what about the "VERONICAS" part? Do I put that in the "Subject:" or what?
