The Best Robocall Blocking Apps and Tools for Avoiding Phone Spam
December 20, 2021
Robocalls come in two forms. A small minority of them are requested by phone owners for appointment and prescription reminders. The vast majority are spam calls offering extended car warranties, credit “forgiveness” programs, or similar questionable products. Some go so far as to suggest you have outstanding arrest warrants or are going to be jailed by the IRS. They’re annoying and overwhelmingly common, and the only way to deal with them is knowing how to block spam calls.
How Do Robocalls Work?
Robocalls take advantage of vulnerabilities with the phone system to send millions of calls an hour. Here’s how a typical robocall system works:
- Gateway carriers take calls from overseas robo dialers and spoof them to look like they come from within the U.S. phone system. The carrier is either unaware of or chooses to ignore the nature of the call.
- The call is passed from the carrier to phone carriers and from there directed to your phone. At this point, most people hang up on the call, but a small number of call recipients take the bait and engage with the robocall.
- Anyone who takes the call is added into the robocaller’s automated phone tree and sent questions to evaluate whether they’re suitable targets for the scam or telemarketing scheme.
When the robocall identifies a qualified lead, the number is sold to a buyer, who attempts to sell a product or service (real or fraudulent). The process succeeds often enough to make robocalling economically profitable: approximately one in three Americans report falling for phone scams.
How to Block Spam Calls
While you can block robocalls as they arrive, it’s much more effective to use a call blocker app. Below are some of the best robocall apps on the market:
