After a couple businesses sent me texts that I did not want, and I got charged for the "privilege " of receiving them, I had AT&T turn off the texting. I never text anyone...I call. End of that problem. And all these numbers I don't know? I google them, and there are usually a number of people who have already received calls and left info on who they are, and what they are pushing. I have more "rejects" listed than actual numbers of people I call, but once they are on there, they can waste their time calling, and I never hear my cell phone ring. I leave my answering machine on to screen for me, too.
