Text messages: Deciphering mobile marketing from fraud

I got a text today that read "Your VISA account is closed due to unusual activity, call us at 1-(888) 568-2788." After doing a quick search online I came across 800notes.com that shows a string of other people like me who have gotten these texts but with a different 800 number.

It's fraud, but it made me second guess that maybe we did have an issue with our company credit card. I have mixed feelings about mobile marketing as I don't like having to pay for someone's ad to me, but this is even worse - paying for spam and fraud. Ug.
