Just received 2 texts back to back from this number. Searching online for it reveals it's not registered with any phone company so now they've figured out how to spoof numbers for text messages too! And on texts you just see a number so they don't have to worry about spoofing the caller ID.

Tried link from private browsing session. Led to http://www.sales-mk.com which "looks" like a Michael Kors (clothing retailer) website, but on research you find that it's a fake website.
