1. Check with your phone carrier
A federal law enacted in December — the Pallone-Thune TRACED Act — requires phone companies to adopt authentication technology that enables them to determine whether incoming calls are legitimate before calls reach their customers’ phones.
But even before that, some major phone carriers had introduced new free anti-robocall features or were working on authentication technology, as we reported in 2019. So, contact your phone company or check its website to see what features, apps or other technology it offers to customers seeking to cut down on unwanted calls.
