Lately I have seen an uptick in calls from unblocked numbers, almost all of them out of state (FL, CA, WY, etc.) that hang up as soon as I answer. These are different from robo-calls where I answer and there is a pause before the robot kicks in to sell me auto-insurance or whatever. The hang up is almost immediate when I answer. Usually I don't answer any call that I don't recognize. In that case, when I get a call like that, it rings once or twice and then stops. But in the last week or two, I've had several calls from places where I knew someone but perhaps not their cell number so answered just in case it was someone I knew. Anyway, more of them lately. What's up with this - someone checking for active numbers? I feel like the up tick started shortly after we visited San Francisco. Like somehow my number showed up on someone's radar or something, or went through a cellular network who grabbed my number for some purpose.
