Notice you've been getting a TON of unknown callers in the past few months. You're not alone. There's a great hidden feature on iPhones that will help you prevent any unknown callers.
iPhones can now silence any unknown caller before a notification even pops up on your phone thanks to a hidden update as part of iOS 13. The "Silence Unknown Callers" feature automatically silences all unknown calls and only appear if they caller left a voicemail.
To enable the feature just go to your SETTINGS page, go to the PHONE settings, and then TURN ON "Silence Unknown Callers."
Keep in mind that if you're waiting for a callback for a job or your UberEats order that they will also be silenced, but it's a small price to pay!
