iOS 26 Call Screening: The Complete Guide to Taking Control of Unknown Calls

A Smarter Way to Handle Unknown Callers

We’ve all been there—your phone rings, you glance at the screen, and it’s an unknown number. Is it a spam call? A scammer? Or could it be an important call you can’t afford to miss?

With iOS 26, Apple has introduced a powerful new feature called Call Screening that puts you back in control. Instead of interrupting you with every unknown call, your iPhone silently answers in the background, asks the caller for their name and reason for calling, and transcribes their response—all before your phone ever rings. You then see the transcript on your screen and decide whether to answer, send a text, or ignore.

This guide walks you through everything you need to know: how to enable Call Screening, choose the right style for your needs, filter unknown calls out of your main history, and mark trusted numbers so they ring you directly next time.

What Call Screening Actually Does

When an unknown number calls your iPhone, Call Screening takes over silently in the background. Here’s what happens step by step:

Step	Action
1	Your iPhone answers the call without ringing.
2	An automated voice asks the caller for their name and reason for calling.
3	The caller’s response is transcribed in real time.
4	Your iPhone rings, displaying the transcript on your screen.
5	You decide to answer, send a text, or ignore the call.

Key Advantage: This feature works on any iPhone compatible with iOS 26—it does not require Apple Intelligence or the latest hardware. Apple officially states it is an “on-device feature that helps users quickly decide if an incoming call from an unknown number is important or not”.

How to Enable Call Screening (and Choose Your Style)

Step-by-Step Instructions

Open the Settings app on your iPhone.
Scroll down and tap Apps.
Tap Phone.
Scroll down to the Screen Unknown Callers section.
Choose one of the three options:

Option	What It Does	Best For
Never	Call Screening is off. Unknown numbers ring like normal.	Users who receive many legitimate first-time calls.
Ask Reason for Calling	iPhone screens the caller, then rings you with their transcribed response.	The best balance—control without unwanted interruptions.
Silence	Unknown numbers are silenced and sent directly to voicemail.	Absolute peace and minimal interruptions.

Tip: Siri speaks in your iPhone’s default language during the screening process. If you’re having trouble finding the option, check that your device’s language and region settings are set to a supported combination.

Keep Junk Out of Your Main Call List

Call Screening works alongside two powerful filters that help keep your call history clean:

1. Unknown Callers Filter

Moves missed calls and voicemails from unknown numbers into a dedicated Unknown Callers list.
Keeps your main call history focused on contacts you know.

2. Spam Filter

Silences calls flagged by your carrier as spam or fraud.
Drops them into a separate Spam list.

To enable these filters:

Go to Settings → Apps → Phone.
Toggle on the filters you want to use.

To view filtered calls later:

Open the Phone app.
Tap Calls (Unified layout) or Recents (Classic layout).
Tap Filter → Choose Unknown Callers or Spam.

Mark Numbers as “Known” (So They Ring You Next Time)

What if a legitimate caller gets screened, but you want them to reach you directly in the future? You can mark them as Known.

How to Mark a Number as Known

Open the Phone app.
Tap Filter → Unknown Callers.
Find the call from the person you want to whitelist.
Tap Mark as Known next to the call.

What happens next:

That number can now call or text you across Phone, FaceTime, and Messages without being screened.

How to Undo (Mark as Unknown)

Open the Contacts app.
Find the contact and tap Other Known.
Select the number and tap Mark as Unknown.

Pick the Right Option for You

Not sure which setting to choose? Here’s a quick decision guide:

If You Want…	Choose…
To see who’s calling and why before being interrupted	Ask Reason for Calling
Complete peace and minimal distractions	Silence
No screening at all (e.g., for business lines with many first-time callers)	Never

For most users, Ask Reason for Calling offers the ideal balance—you stay in control without missing important calls.

Final Thoughts: A Feature Worth the Upgrade

iOS 26’s Call Screening is one of those features that, once you start using it, you’ll wonder how you ever lived without it. It gives you back control over your phone, reduces interruptions from spam and scams, and ensures you never miss an important call from an unknown number.

The bottom line: Turn on Ask Reason for Calling, add the Unknown Callers filter, and mark real contacts as Known. You’ll get fewer interruptions, a cleaner call history, and the peace of mind that comes with knowing you’re in control.
