How to Stop Spam Calls on Your iPhone (2026)

Your iPhone lights up with calls from numbers you do not recognize, sometimes sharing your own area code, sometimes flagged "Scam Likely." You decline one and two more arrive an hour later. It is exhausting, and it can feel like there is no way to make it stop.

The good news: iOS 26 added the strongest native call-screening tools Apple has ever shipped, and you can stack them with free carrier blocking and a regulatory registration for layered protection. This guide walks through every verified method, ordered quickest and most effective first, with the exact menu paths.

One note before you start. iOS 26 moved Phone settings. They now live under Settings > Apps > Phone, not Settings > Phone. Older guides pointing to the old path will not match, so follow the breadcrumbs here exactly.

Why You Are Getting Spam Calls

Understanding the cause helps you pick the right fix. Spam calls usually trace back to a few things.

• Caller ID spoofing. Scammers fake the number that shows on your screen, often using your own area code and prefix ("neighbor spoofing") so the call looks local and familiar.
• Your number is on a list. It may have been sold by a data broker, leaked in a breach, typed into a web form, or hit by robocallers dialing numbers in sequence.
• You interacted with a past call. Answering, or pressing a key to "opt out," confirms your number is live and tends to increase the call volume.
• The number is not yet flagged. If your carrier has not marked the caller as spam, the call rings through normally unless you have on-device or carrier filtering on.
• The caller is not in your Contacts. Features like Silence Unknown Callers and Call Screening key off your contact list, so anyone unsaved is treated as unknown.

Turn On Call Screening (Ask Reason for Calling)

This is the single strongest native tool in iOS 26. Instead of silently dropping unknown calls, your iPhone answers in the background and asks who is calling before it rings you. It runs on-device.

1. 1.Open the Settings app.
2. 2.Tap Apps.
3. 3.Tap Phone.
4. 4.Find the Screen Unknown Callers section.
5. 5.Tap Ask Reason for Calling.

When an unknown number calls, your iPhone silently answers, asks for the caller's name and reason, transcribes the response, then rings you and shows that text on screen. You can accept, decline, or ask for more information, so legitimate callers get a chance to identify themselves before you pick up.

One limit worth knowing: Call Screening is disabled while roaming, regardless of your setting.

Silence Unknown Callers (the Stricter Option)

If you prefer zero interruptions over screening, this sends every call from a number not in your Contacts straight to voicemail with no ring.

1. 1.Open Settings > Apps > Phone.
2. 2.Under Screen Unknown Callers, tap Silence.

Calls from numbers not in your Contacts (and not in recent outgoing calls, Mail, or Messages) are silenced, sent to voicemail, and still appear in Recents. On a Mac, you can set this in the Phone app via Phone > Settings > Calls.

Be deliberate here. Silencing all unknown callers can make you miss legitimate calls from unsaved numbers: doctors' offices with rotating lines, delivery drivers, recruiters, schools, and switchboards. For most people, "Ask Reason for Calling" is the better choice because it screens rather than silently drops. Also note this is disabled while roaming, and after you place a 911 call it pauses for 24 hours so callbacks get through.

Switch On Carrier Spam Call Filtering

Separate from Silence Unknown Callers, iOS 26 can filter calls your carrier flags as spam. These two are independent settings; turning one on does not turn on the other.

1. 1.Open Settings > Apps > Phone.
2. 2.Scroll to Call Filtering.
3. 3.Turn on the Spam toggle. Calls your carrier identifies as potential spam or fraud are silenced, sent to voicemail, and moved to a Spam list.
4. 4.Turn on the Unknown Callers toggle to move missed calls and voicemails from unknown numbers into a dedicated Unknown Callers list.

To review a filtered list, tap the Filter button, then select Unknown Callers or Spam. The filter appears in the Recents tab (Classic view) or the Calls tab (Unified view). Carrier spam labeling happens independently of Apple's features, and availability can vary by carrier, region, language, and device.

Block a Specific Repeat Caller

When one number keeps getting through, block it directly. This stops them across Phone, FaceTime, Messages, and Mail at once.

1. 1.Open the Phone app.
2. 2.Tap Favorites, Recents, or Voicemail.
3. 3.Tap the Info button (the "i") next to the name or number.
4. 4.Scroll down and tap Block this Caller.
5. 5.Tap Block Contact to confirm.

A blocked person can still leave a voicemail (you just get no notification), and they are not told they were blocked. The block syncs across your Apple devices.

Manage and Unblock Your Blocked List

In iOS 26 your blocked numbers live in one unified place, no longer split across Phone, Messages, FaceTime, and Mail.

1. 1.Open Settings.
2. 2.Tap Privacy & Security.
3. 3.Tap Blocked Contacts.
4. 4.To add someone, tap Add Blocked Contact, choose the contact, then tap Block Contact.
5. 5.To unblock, tap Edit, tap the delete button next to the contact, then tap Unblock.

Turn On Live Voicemail to Catch Legitimate Calls

Screening and silencing route unknown calls to voicemail, so Live Voicemail lets you read what someone is saying in real time and pick up if the call matters.

1. 1.Open Settings > Apps > Phone.
2. 2.Turn on Live Voicemail.

To sync it across devices, go to Settings > [your name] > iCloud > tap See All next to Saved to iCloud > turn on Phone & FaceTime.

Report Spam Voicemails to Apple

iOS 26 lets you report spam voicemails so Apple can act on them.

1. 1.Open the Phone app and go to Voicemail.
2. 2.Tap into a voicemail from an unknown number.
3. 3.Tap the Report Spam button.
4. 4.Choose to report and keep the message, or report and delete it.

Reporting sends the voicemail to Apple but does not block the caller. If you want them gone, block them separately using the steps above.

Use Free Carrier-Level Blocking

Carrier filtering stops calls before they reach your iPhone, which is the earliest possible layer. T-Mobile's Scam Shield is one verified example.

• Scam ID is on by default and flags suspected scam calls on screen as "Scam Likely."
• Scam Block (free) automatically blocks calls marked as scam. Enable it by dialing #662# from your T-Mobile device, through the T-Life app toggle, via My T-Mobile, or by calling 611 for DIGITS numbers.
• Block individual numbers through Block Contacts in the T-Life app.
• Optional Scam Shield Premium ($4/month per line) adds categorized call-to-voicemail routing, reverse number lookup, and voicemail-to-text.

It requires qualifying T-Mobile service and a capable device. Other major carriers offer their own free call-filtering apps; check your carrier's official tools to see what is included on your plan.

Register With the National Do Not Call Registry

This last layer reduces legal telemarketing, though it will not touch scammers.

1. 1.Register free at DoNotCall.gov, or call 1-888-382-1222 (TTY: 1-866-290-4236) from the phone you want to register.
2. 2.If registering online, click the confirmation link in the email within 72 hours.
3. 3.Your number appears on the registry the next day.

The registry is a do-not-call list for law-abiding companies. It does not block calls, legitimate telemarketers have up to 31 days to stop, and it will not stop illegal robocalls. If unwanted sales calls continue after 31 days, file a complaint at complaints.donotcall.gov.

Frequently Asked Questions

What is the difference between Silence Unknown Callers and the carrier Spam filter?

They are two separate settings. Silence Unknown Callers routes anyone not in your Contacts to voicemail, while the Call Filtering Spam toggle silences only calls your carrier flags as spam or fraud. Turning one on does not turn on the other, so enable both for fuller coverage.

Why is my call screening not working sometimes?

Call Screening and Silence Unknown Callers are disabled while you are roaming, regardless of your setting. And for 24 hours after you place a 911 call, screening is disabled so emergency callbacks reach you.

If I report a spam voicemail, does that block the caller?

No. Reporting a spam voicemail in iOS 26 sends it to Apple but does not block the number. Blocking is a separate action you take from the Phone app or your Blocked Contacts list.

Will a blocked caller know they have been blocked?

No. They receive no notification. They can still leave a voicemail, but you will not get an alert for it, and the block syncs across your Apple devices.

Does the Do Not Call Registry stop scam calls?

No. The registry only deters law-abiding telemarketers, and even then allows up to 31 days before calls stop. It does not block calls and is useless against scammers and illegal robocalls, which is why on-device screening and carrier filtering matter more.

Why do spam calls share my own area code?

That is "neighbor spoofing." Scammers fake the caller ID to show a local number with your area code and prefix so the call looks familiar and you are more likely to answer. Call Screening helps here because it forces the caller to identify themselves before you pick up.
