Everyone finds unwanted calls irritating and annoying. In particular, network operators have become a pest with their robocalls. But they are not the only ones. Entire industries are thriving on the unwanted calls phenomenon. I got a tip from @tundeiness yesterday evening about McAfee mobile security on his Sony smartphone being an effective tool in blocking unwanted calls and SMS. Here is his account compiled from his tweets: Now, I know that McAfee Antivirus & Security app is available for Android devices. I checked in Play Store, and filtering of calls and SMS is listed as one of the features it offers. I am not a huge fan of antivirus apps on smartphones. I think they are unnecessary But I do recommend that you look at this one for the sake of the filtering unwanted calls. It does not appear that the call blocker feature of the app is available for iPhones and iPads. Support for that feature seems limited to only Android smartphones and Android tablets that can make telephone calls.To add numbers to your block list, you can punch in the numbers manually, or import from call logs, message list, or contacts. Blocked callers get a Busy tone when they call your line. If you use an Android smartphone and are tired of the crap that your network throws at you, go get it here.
