  • Reject or ignore calls from unknown phone numbers. If it is important and not a robocall, the caller will leave a message for you.
  • End a call as soon as you realize it is a robocall. Never act on prompts given during robocalls as doing so will open up a floodgate of robocalls.
  • Block robocall numbers by using third-party applications on your cell phone. Some cell phones also have built-in call-blocking features that are efficient in blocking robocall numbers. Alternatively, report robocall numbers to your phone company and ask them to stop such numbers from calling you.
