Bothered by robocalls on your mobile phone? I haven't been so much, but my wife has been getting lots of them for some reason. Quite aggravating. The following article explains a couple of steps one can take to try to deflect robocalls. I checked, and AT&T (our carrier) does support "nomorobo". However, this service doesn't work on landlines.
If your carrier doesn't support "nomorobo", another option to try is the TrueCaller app for the iPhone. Read here. It looks to be a bit more work to use, but maybe this is better than getting a robocall.
