How to Enable Call Screening for Unknow Callers on Any iPhone [easy]

To enable the new Call Screening feature for unknown callers on your iPhone running iOS 26, which uses an AI voice to ask the caller their reason for calling before your phone even rings, first open the Settings app. Next, scroll down and tap on Apps, then select the Phone app, and under the "Screen Unknown Callers" section, choose the option Ask Reason for Calling; this will automatically intercept calls from numbers not in your contacts, give you a live transcript of the caller's response, and allow you to decide whether to answer or ignore.
