The text message I got is "Hi, I'm Jill. Based on your resume you match a position I'm filling. If you register at jobnab.com we can discuss the details if you're interested." It appears that jobnab is a headhunting service. I've registered with Monster, SnagAJob, Indeed, and CareerBuilder and applied to numerous companies through their application interface programs (Taleo and others). Yes, I've been applying to many jobs and there's no telling which site they got my info from. When I tried to do the reverse phone lookup, it seems the cell phone is registered on the north side of Chicago.
