What Are Unknown Callers on iPhone?
On your iPhone, an "unknown caller" refers to any incoming call from a number not saved in your contacts list. This includes telemarketers, robocalls, and other unsolicited calls. Managing these calls is essential to maintain your privacy and reduce interruptions.
How Can I Silence Unknown Callers on My iPhone?
