I don't get them on my Sprint phone, somehow. My work phone is AT&T, it's constantly getting them (I want to have my Chinese coworker listen to a few of the Chinese recordings...) so I just leave it powered off most of the time. No big deal, maybe 4 legitimate inbound calls in 4 years, of which I missed 3.
