Key Takeaways
- Turn on call screening in Settings > Apps > Phone > Screen Unknown Callers, then select “Ask Reason for Calling.”
- The feature is free, runs on-device, and works on any iPhone 11 or later that supports iOS 26, without Apple Intelligence.
- Call screening prompts unknown callers to say their name and reason, then shows a live transcription so you can decide whether to answer.
- Outbound business calls often fail when legitimate callers hang up at the screening prompt, which creates missed connections and lost revenue.
- Plura AI improves connect rates with branded caller ID and AI voice agents that work with iOS 26’s screening layer. See a live demo to review the impact on your outbound performance.
Turn On Call Screening on iPhone (iOS 26)
Call screening activates in a few taps on any compatible iPhone running iOS 26 or later.
- Open the Settings app on your iPhone.
- Scroll down and tap Apps.
- Select Phone from the app list.
- Scroll to Screen Unknown Callers.
- Tap Ask Reason for Calling to enable screening.
- Exit Settings. Your selection saves automatically.
On iOS 26, the Phone settings moved to Settings > Apps > Phone, replacing the older Settings > Phone layout. If you follow the older path, the Screen Unknown Callers option will not appear.
Each option under Screen Unknown Callers behaves differently:
- Never: Unknown numbers ring normally and skip screening.
- Ask Reason for Calling: iPhone answers, plays an automated voice that asks for the caller’s name and reason, then rings you with their spoken response transcribed on screen.
- Silence: Unknown numbers go straight to voicemail without ringing.
The caller speaks their response, not types it, and your iPhone rings with a real-time transcription on the incoming-call screen. You then choose to answer, decline, or send the call to voicemail.
iPhone Models That Support Call Screening
Call screening requires iOS 26 or later and appears on every iPhone model that can run iOS 26, not only the newest AI-capable devices. Apple’s iOS 26 compatibility list includes these models:
| iPhone Model | iOS 26 Support | Call Screening Available |
|---|---|---|
| iPhone 11, 11 Pro, 11 Pro Max | Yes | Yes |
| iPhone 12, 13, 14, 15 (all models) | Yes | Yes |
| iPhone 16, 16e, 16 Pro, 16 Pro Max | Yes | Yes |
| iPhone 17, 17 Pro, 17 Pro Max, iPhone Air | Yes | Yes |
| iPhone SE (2nd gen and later) | Yes | Yes |
| iPhone XS, XR, X, 8 and earlier | No | No |
Call screening does not depend on Apple Intelligence or a specific Neural Engine. Availability still depends on language and region, including English (US, UK, Canada, Australia, and others), Cantonese, French, German, Japanese, Korean, Mandarin Chinese, Portuguese (Brazil), and Spanish.
Cost and Privacy for iOS Call Screening
iOS 26 call screening is completely free. It is built into the iPhone’s Phone app, so there is no subscription, separate app, or carrier add-on. The feature processes everything on-device, which means Apple does not see the caller’s transcripts. Standard cellular rates still apply when you answer a call, but screening itself has no extra charge.
Why Your iPhone May Not Be Screening Calls
If call screening is not working or the option is missing, work through these checks in order, starting with the most common causes.
- Check your iOS version: Go to Settings > General > Software Update and confirm you run iOS 26 or later, since earlier versions do not include this feature.
- Confirm model compatibility: Call screening requires an iPhone 11 or later, or an iPhone SE (2nd generation) or later.
- Verify language and region: Apple limits the feature to specific language and region combinations. Check Apple’s feature availability page to confirm support.
- Restart your iPhone: A restart often clears settings glitches that hide or disable features.
- Confirm the settings path: On iOS 26, use Settings > Apps > Phone > Screen Unknown Callers. The older Settings > Phone path will not show this menu.
- Check roaming status: Call screening does not function while you are roaming.
- Wait after emergency calls: The feature pauses for 24 hours after you call emergency services.
- Review Focus modes: Active Focus modes such as Do Not Disturb, Sleep, or Work can send calls straight to voicemail. Open Control Center and turn off any active Focus.
Call screening only affects numbers that are not saved in Contacts. Save key numbers such as family, doctors, and schools so their calls always ring through.
How iOS 26 Call Screening Handles Unknown Callers
iOS 26 Call Screening intercepts calls from numbers that are not in Contacts and plays a message asking the caller to state their name and reason before the phone rings. Siri provides the spoken interface that collects the caller’s details. You see a real-time transcription on screen and choose to answer, decline, or send the call to voicemail.
The entire process runs on-device, so Apple does not receive the transcripts. Call Screening in iOS 26 also differs from Live Voicemail. Screening happens before the phone rings to gather basic details, while Live Voicemail starts after a call reaches voicemail and transcribes the full message.
Call Screening only asks callers to identify themselves before the call rings and does not record or transcribe the full conversation. It also does not verify identity or block every spam call, since a scammer can still provide a convincing but false reason.
Turn Off Call Screening on iPhone
You can disable or change call screening behavior at any time.
- Open Settings on your iPhone.
- Tap Apps, then select Phone.
- Scroll to Screen Unknown Callers.
- Select Never to restore normal ringing for unknown numbers.
- Or select Silence to send unknown calls to voicemail without a screening prompt.
Your selection saves automatically. You can switch between options whenever your needs change.
iOS 26 Call Screening vs. Third-Party Apps
The main tradeoff between Apple’s built-in screening and third-party apps centers on cost, privacy, and depth of interaction. Apple’s option is free and runs on-device, while many third-party tools add subscription fees and may collect contact or usage data. The table below compares the approaches across key factors.
| Feature | iOS 26 Call Screening | Third-Party Apps |
|---|---|---|
| Cost | Free, built into iOS | Often require subscription ($19.99–$139.99/year) |
| Privacy | On-device processing; Apple does not see transcripts | Varies; some collect contact and usage data |
| Caller interaction | Asks name and reason via automated voice | May hold fuller conversations or take messages |
| Spam database | Carrier-reported and on-device intelligence | Often use community-reported spam databases |
| Platform | iPhone only | Some work on iPhone and Android |
Apple’s built-in feature usually covers personal use, especially for users who prioritize privacy and cost control. Third-party apps can add richer call handling or cross-platform coverage, which may matter more for specific business workflows.
Business Impact of iOS 26 Call Screening
For outbound teams, iOS 26 call screening creates a measurable contact-rate problem. The Associated Press reported that legitimate callers such as delivery drivers, mechanics, and plumbers often hang up instead of responding to the prompt, which can sound like voicemail or an automated system.2 Sales, service, and field operations feel this as missed connections on calls that never reach a live person.
The core issue is caller identity. When your team calls a number that is not saved in the recipient’s contacts, iOS 26 intercepts the call before it rings. Many outbound callers hang up at the prompt instead of speaking to an automated voice, which turns a paid outbound attempt into a silent voicemail drop.
Plura AI addresses this at the carrier level. As an FCC-licensed audio bridging carrier, Plura issues branded caller ID directly.1 Calls present with the company’s name and reason for calling, not an unfamiliar number. Plura’s AI voice agents also communicate with iOS 26’s call-screening layer so legitimate business calls display clear identity and reach the person on the other end. For high-volume outbound operations, this shift often separates a connected conversation from a screened-out voicemail.

Frequently Asked Questions
What iOS version do I need for call screening?
You need iOS 26 or later. Check by going to Settings > General > Software Update. Earlier versions only include Silence Unknown Callers, which sends unknown calls to voicemail without collecting details. The Screen Unknown Callers menu with the “Ask Reason for Calling” option appears only in iOS 26.
Does call screening cost money?
iOS 26 call screening is free and built into the iPhone. There is no subscription, in-app purchase, or carrier fee for the feature itself. Standard cellular rates apply if you answer the call. The feature runs on-device, so Apple does not charge for processing and does not send call transcripts to third parties.
Why can’t I find Screen Unknown Callers in my settings?
The option usually disappears when one of the feature requirements is not met. Start by confirming that you run iOS 26 in Settings > General > Software Update, since earlier versions do not include this menu. Next, make sure your iPhone model matches the supported list, such as iPhone 11 or later or iPhone SE (2nd generation) or later. Then confirm that your region and language appear on Apple’s supported list, because availability varies by market. If you are roaming, the option can remain hidden until you return to your home network. After these checks, restart your iPhone and navigate to Settings > Apps > Phone > Screen Unknown Callers. The older Settings > Phone path will not show this option on iOS 26.
Does call screening work with contacts?
Call screening only applies to numbers that are not saved in Contacts. Calls from saved contacts ring through normally without any prompt. Save important numbers such as family members, doctors, schools, and employers so their calls are never intercepted. Apple also notes that large organizations may use multiple outbound numbers, so saving one line does not guarantee that every line from that organization appears as a known contact.
How is iOS 26 call screening different from Silence Unknown Callers?
Silence Unknown Callers, available since iOS 13, sends every unknown call straight to voicemail without ringing or collecting information. Call screening with “Ask Reason for Calling” actively asks for the caller’s name and reason, then rings you with that context displayed on screen. The iOS 26 feature creates a middle ground between allowing all unknown calls to ring and silencing them completely.
Conclusion
iOS 26 call screening gives iPhone users more control over unknown callers before the phone rings. The path Settings > Apps > Phone > Screen Unknown Callers is specific to iOS 26 and differs from older versions. As noted earlier, compatible iPhones and supported regions can use the feature without Apple Intelligence.
For outbound teams, iOS 26 screening highlights how caller identity drives answer rates. Plura’s FCC-licensed carrier infrastructure issues branded caller ID at the carrier level, and its AI voice agents work with iOS 26’s screening layer so your calls present with recognizable identity instead of an unfamiliar number.
