A robocall is a phone call that uses a computerized autodialer to deliver a pre-recorded message, as if from a robot. Robocalls are often associated with political and telemarketing phone campaigns, but can also be used for public service, emergency announcements, or scammers. Multiple businesses and telemarketing companies use auto-dialing software to deliver prerecorded messages (appointment reminders, booking details, etc.) to millions of users. Some robocalls use personalized audio messages to simulate an actual personal phone call. The service is also viewed as prone to association with scams.
As of June 2019, phone companies may, by default, block incoming robocalls.
