1. Reject anonymous calls automatically – Many robocalls come up as “anonymous” on your caller ID, while most businesses and human beings come up as identifiable phone numbers.
  2. Join the National Do Not Call Registry list – Scammers don’t follow the rules, nor do they care about this list. Still, it’s smart to register your number. All you have to do is go to the website donotcall.gov.
  3. Use carrier tools to block unwanted calls – The four major carriers have tools to identify, filter and prevent suspected nuisance numbers from calling or texting your phone. Most require an extra monthly fee to activate the caller ID service, but network-level blocking is free across all the carriers.
  4. Use the best apps to block robocalls – Another way to stop nuisance calls is via call-blocking apps. These apps can identify who is calling you and block unwanted calls that show up on a crowdsourced spam and robocaller list.
  5. Some phones block robocalls automatically – Samsung’s flagship Galaxy and Note smartphones have a native feature called Smart Call that automatically screens and flags suspicious numbers.
  6. Block individual phone numbers – A feature to block specific numbers is available on any iPhone and Android. Although this cannot possibly stop every robocall and spammer number, you can at least block the recurring ones.
  7. Set your phone on do not disturb – To block every number except your most trusted contacts or favorites, you can turn on your iPhone or Android phone’s built-in Do Not Disturb Mode. Just keep in mind that you will miss some legitimate calls, but unknown callers have the option to leave a voice message.
