Key Takeaways
- The iOS call screening feature in iOS 26 uses Siri to intercept unknown calls, ask callers to identify themselves, and display a live transcript so you can decide whether to answer, decline, or end the call.
- Enable the feature in Settings > Apps > Phone > Screen Unknown Callers > Ask Reason for Calling. It is off by default and only applies to numbers not saved in your contacts.
- Call screening differs from Silence Unknown Callers and Live Voicemail because it provides context before your phone rings. You can make an informed decision instead of sending everything to voicemail.
- If the setting is missing, verify you are on iOS 26 or later, your region and language are supported, Live Voicemail is enabled, and no third-party caller ID apps are interfering.
- Businesses can improve pickup rates by presenting branded caller ID that works with iOS 26 screening. Book a live demo with Plura AI to see how it integrates.
How iOS Call Screening Works
iOS 26’s call screening feature uses Siri to intercept calls from numbers not saved in your contacts. When an unknown number calls, your iPhone answers silently, plays a prompt asking the caller to identify themselves and state their reason for calling, and displays a real-time transcript on your screen. You read the transcript and decide whether to answer, decline and send the call to voicemail, or end the call.
The feature sits alongside two older iOS tools that handle unknown calls differently.
- Silence Unknown Callers (available since iOS 13) sends unknown calls straight to voicemail without ringing. It provides no screening, no context, and no choice.
- Live Voicemail (iOS 17+) transcribes a voicemail in real time after the call goes to voicemail.
Call screening happens before your phone rings. You see context on every unknown call and can make an informed decision. That timing separates it from every prior iOS call-management tool.
Turn On Call Screening in iOS 26
Use these steps to turn on the iOS call screening feature.
- Open the Settings app on your iPhone.
- Tap Apps, then tap Phone.
- Scroll down and tap Screen Unknown Callers.
- Select Ask Reason for Calling.
The feature is off by default. You must enable it manually after updating to iOS 26. In some regions, the setting may appear under “Call Screening” instead of “Screen Unknown Callers.”
Call screening only applies to numbers not saved in your contacts, so calls from saved contacts ring normally. To avoid screening important calls, save frequently used numbers such as family, your doctor’s office, your child’s school, and delivery services. Apple specifically recommends saving both the main office number and a direct number for organizations that may call from either.
Turn Off Call Screening on iPhone
You can disable the iOS call screening feature in a few taps.
- Open the Settings app.
- Tap Apps, then tap Phone.
- Scroll down and tap Screen Unknown Callers.
- Select Never.
Choosing “Never” turns off screening completely. Unknown calls will ring normally again. Selecting “Silence” instead sends unknown calls to voicemail without ringing, similar to the older Silence Unknown Callers feature.
Turning off call screening means Siri no longer answers unknown calls or asks callers for their name and reason. Apple also documents that call screening does not work while roaming. Travelers should confirm the feature is set to “Never” before going abroad to avoid unexpected cellular usage.
Fix Missing Call Screening on iPhone
Several common issues can hide the “Screen Unknown Callers” or “Ask Reason for Calling” options.
- Your iPhone is not running iOS 26 or later. Check: Settings > General > Software Update. If an update is available, install it. Call screening requires iOS 26 or later.
- Your region or language is not supported. Apple lists support for Cantonese, English, French (Canada and France), German, Japanese, Korean, Mandarin Chinese, Portuguese (Brazil), and Spanish variants. If your device region is set to an unsupported country, the option disappears. Check: Settings > General > Language & Region.
- Your carrier does not support the feature. Call screening works with most major carriers that support Visual Voicemail. If you are on a smaller carrier or MVNO (Mobile Virtual Network Operator), check with your provider.
- Live Voicemail is disabled. Live Voicemail is the underlying technology for call screening and must be enabled first. Check: Settings > Apps > Phone > Live Voicemail.
- Low Power Mode is active. Low Power Mode is commonly reported to interfere with call screening. Turn it off in Settings > Battery.
- A third-party app is intercepting calls first. Caller ID or spam-filtering apps can block Apple’s screening feature from activating. Disable them at Settings > Apps > Phone > Call Blocking & Identification.
- You are looking in the wrong place. Use the Settings search bar. Pull down on the main Settings screen and type “Screen Unknown Callers” or “unknown callers.”
If the feature still is not available after these steps, the alternatives Silence Unknown Callers and Live Voicemail provide partial protection while you wait for broader carrier or regional support.
What “Screening Call” Means on iPhone
When you see “Screening call” on your iPhone screen, Siri has answered an unknown call and is asking the caller to identify themselves.
From the caller’s perspective: The caller hears an automated message such as: “The person you’re calling is using a screening service. Please state your name and reason for calling.” The caller then speaks their response.
From your perspective: Your iPhone displays a live transcript of the caller’s response in real time, even when your screen is locked. You might see something like:
“Hi, this is Dr. Martinez’s office calling to confirm your appointment tomorrow at 2 PM.”
You then have three choices.
- Answer the call.
- Decline, which sends the call to voicemail.
- End the call.
Most spam callers and robocalls hang up when they encounter the interactive prompt, since their automated systems cannot respond to interactive questions. In testing, over 90% hang up within 2 seconds of Siri speaking, since scam scripts require a human response.1
One important note: iOS 26 automatically disables call screening for 24 hours after you call emergency services. Emergency responders can call back via unknown numbers without being screened.
Compare Call Screening, Silence Unknown Callers, and Live Voicemail
| Feature | What It Does | When to Use It |
|---|---|---|
| Call Screening (iOS 26) | Siri answers unknown calls, asks for name and reason, shows live transcript before you decide | You want context on unknown calls without missing legitimate ones |
| Silence Unknown Callers (iOS 13+) | Sends unknown calls straight to voicemail without ringing | You rarely get legitimate calls from unknown numbers |
| Live Voicemail (iOS 17+) | Transcribes voicemail in real time as the caller leaves a message | You want to screen voicemails without answering |
These features work together as a layered system. Call screening happens before the phone rings. If you decline a screened call, it goes to voicemail, where Live Voicemail picks up and transcribes whatever the caller says next. 9to5Mac’s Ryan Christoffel describes “Ask Reason for Calling” as “a great middle ground” between allowing all calls to ring and silencing all unknown callers.
Why iOS Call Screening Matters for Your Team
The iOS call screening feature gives you context on every unknown call without forcing a choice between missing legitimate callers and being interrupted by spam. You can enable it in under a minute at Settings > Apps > Phone > Screen Unknown Callers > Ask Reason for Calling. Once it is on, most robocalls will drop before your phone ever rings.
For business owners and outbound teams, iOS 26 call screening introduces a new friction layer that changes how unknown calls land with customers. Plura AI helps businesses present branded caller ID at the carrier level and communicate with iOS 26’s call-screening layer so calls present with the company’s name and reason for calling. This approach turns more screened calls into live conversations. Book a live demo with Plura to see how it works for your operation.
Frequently Asked Questions
How do I stop my iPhone from screening calls?
Go to Settings > Apps > Phone > Screen Unknown Callers and select Never. This disables screening entirely. Unknown calls will ring normally, and missed calls will appear in your Recents list as usual. If you want unknown calls silenced but not screened, select Silence instead, which sends them directly to voicemail without ringing.
Why did my phone say “screening call”?
Your iPhone automatically answered an unknown call and asked the caller for their name and reason for calling. The live transcript appears on your screen so you can decide whether to answer, decline to voicemail, or end the call. This occurs when the Screen Unknown Callers setting is set to Ask Reason for Calling in your Phone settings.
Does call screening work with all unknown numbers?
Call screening applies only to numbers not saved in your contacts. Calls from saved contacts bypass screening entirely and ring normally. Numbers that your carrier has already identified as spam may be handled separately by carrier-based spam filtering, which operates independently of Apple’s call screening feature. Call screening does not block all spam calls. Some calls using spoofed numbers may still reach the screening prompt.
Can I customize the call screening message callers hear?
No. Apple does not currently allow customization of the screening prompt. All callers hear the same generic automated message asking for their name and reason for calling. There is no option to add your name, business name, or industry-specific questions to the prompt. The transcription of the caller’s response appears on your screen in real time, but the output is not structured or formatted for export to a CRM or business tool.
Is call screening available in my country?
Call screening is available in over 20 countries and 9 languages, including the United States, United Kingdom, Canada, Australia, Germany, France, and Japan. Apple’s supported language list includes English, French (Canada and France), German, Japanese, Korean, Mandarin Chinese (mainland China, Macao, and Taiwan), Cantonese, Portuguese (Brazil), and Spanish variants. If your device region is set to an unsupported country, the Screen Unknown Callers option may not appear in your Phone settings. Check Apple’s official feature availability page for the current full list, as regional rollout continues.
