A couple of weeks ago Apple released the new iOS 13 for their phones. With this new update they are helping to fight spam callers. They released a feature called “Silence Unknown Callers.” Now this isn’t going to completely stop the spammers from calling, but at least you don’t have to hear the calls. By turning on this feature they will send the calls to voicemail. How this works is the function will silence any numbers that aren’t in your contacts.
