Who called from 3472851728

This is a text spam number. The corporate name linked to it (by reverse look up) is Omnipoint Communications.

This # keeps SMS-ing me and i want it to stop. How do I make it stop?

I received two unsolicited text mesages, one for "GUARANTEED SAVINGS on your GAS&ELECTRIC" and the other for "business partners wanted...."

I have unlimited SMS so its only an annoyance but I wondering how they got my number?   I never got spam texts before.   Only two possibilities: A) started using Twitter about six months ago, or B) joined the National Association of the Self Employed two years ago and they do continue to call me well after I stopped paying my dues.
