How to Stop Spam Calls and Scam Texts on Your iPhone

First, the size of the problem, because it explains why no single switch is enough. According to the FTC's May 2026 consumer alert on new trends in imposter scams, Americans lost 3.5 billion dollars to imposter scams in 2025, nearly 20 percent more than the year before, and reports of government imposter scams jumped 40 percent, driven in part by fake unpaid toll texts. The texts got better, too: the old broken English is gone, the messages are written with AI, they copy the exact wording of E-ZPass or USPS, and they arrive from numbers that change every few hours.

That matters for your strategy. Senders rotate numbers constantly, so blocking them one by one is a losing game. What works is layers: let iOS screen unknown callers before your phone rings, let Messages sweep strangers out of your inbox, let your carrier kill known scam traffic at the network level, and keep a few habits for whatever still slips through. Stacked together, those layers turn the flood into a trickle, and everything below follows that order, most effective first.

iOS 26 gave the iPhone a real receptionist. With Call Screening on, calls from numbers not in your contacts are answered automatically before your phone makes a sound, the caller is asked for their name and reason, and their answer is transcribed live on your screen. Only then does your iPhone ring, and you decide: answer, ignore, or ask for more. Robocallers almost never make it past the question, so the spam call simply never happens to you. Apple documents the feature in its guide to managing unknown callers on iPhone.

Here is the setup:

1. Open Settings > Apps > Phone.
2. Tap Screen Unknown Callers.
3. Pick one of three options: Never (off, every call rings), Ask Reason for Calling (the receptionist described above), or Silence (unknown numbers go straight to voicemail and appear in Recents without ringing).

Ask Reason for Calling is the right pick for most people, because real humans, like a courier or a new dentist's office, will happily say who they are, while machines hang up. Choose Silence only if you want total quiet and genuinely check voicemail. A few honest caveats: saved contacts always ring straight through, screening pauses for 24 hours after you call emergency services, and it does not work while roaming abroad. You need iOS 26, which runs on the iPhone 11 and newer; check Settings > General > Software Update. These tools carry forward into this fall's update too, which we covered in our guide to installing the iOS 27 beta.

Once screening is on, the Phone app quietly files everything instead of bothering you. Tap the Filter button at the top of the Calls screen to find separate lists: one for unknown callers, collecting missed calls and voicemails from unsaved numbers, and a Spam list for calls your carrier has flagged as spam or fraud. Back in Settings > Apps > Phone, confirm the spam filter is on so flagged calls are silenced and filed automatically.

The safety net underneath is Live Voicemail. When a silenced call goes to voicemail, your iPhone shows a live transcript as the person speaks, and if you see your kid's school or your mechanic mid-sentence, you can pick up right then. It is on by default, and it removes the last argument against silencing strangers: you can watch the rare important call arrive.

For the first couple of weeks, glance at those lists every few days and save legitimate numbers to Contacts. After that, trust the system.

Now the texts. iOS 26 replaced the old filtering with proper screening, and it changes the feel of Messages completely. Go to Settings > Apps > Messages and turn on Screen Unknown Senders, or get there inside Messages by tapping the Filters button and choosing Manage Filtering. Apple's support page on screening and filtering texts covers every option.

With screening on, texts from numbers you do not know and have never replied to stop appearing in your main conversation list and stop sending notifications; they wait in an Unknown Senders folder instead. Anything iOS suspects is junk goes one level deeper, into a Spam folder, on by default. When a real person texts from a new number, open the conversation and tap the blue Mark as Known button at the bottom, and they move to your main list permanently.

Two worries we can clear up. One-time sign-in codes still autofill above your keyboard even when the text files into a side folder, so logins keep working. And nothing is blocked or deleted here. Screening only decides what deserves a notification, so a message you were expecting is always findable in the folders, never gone.

Reporting feels like shouting into the void. It is not. Reports train Apple's filters, and forwarded texts help carriers shut down whole sending campaigns. Two ways to do it:

1. Report Junk in Messages. Swipe left on a message from an unknown sender and tap Delete and Report Junk, or open it and tap the Report Junk link at the bottom. iMessages go to Apple along with the sender's details and the message is deleted from your phone. For regular SMS and RCS texts the option depends on your carrier, and one quirk is worth knowing: it disappears once you reply to a conversation, so report first, never answer.
2. Forward to 7726. This is the universal spam hotline run by the carriers, and the digits spell SPAM. Touch and hold the scam message bubble, tap More, tap the forward arrow, and send it to 7726. Your carrier texts back asking for the sender's number, you paste it, done. It is free on every major US network, and the FCC's guide to stopping unwanted robocalls and texts recommends the same habit.

If a scam actually cost you money, also file a report at reportfraud.ftc.gov; those reports are what trigger takedowns.

Blocking is the tool everyone reaches for first, so here is the honest version. Scam operations spoof caller ID and rotate through thousands of numbers, so the number you block today will probably never call again anyway. Where blocking shines is repeat offenders with a stable, real number: the warranty company that calls weekly, the gym that will not take no for an answer.

To block from a call, tap Recents in the Phone app, tap the info button next to the number, scroll down, and tap Block Caller. From a text, open the conversation, tap the name at the top, and tap Block Caller. Blocked callers go straight to voicemail, their texts never appear, and the full list lives under Settings > Apps > Phone > Blocked Contacts.

One more thing: be careful with STOP. Replying STOP to a legitimate business you signed up with, like a pharmacy or an airline, works and is enforced. Sending STOP, or anything at all, to a scam text does the opposite: it confirms a live human reads this number and promotes you to the premium spam lists. If you did not give them your number, do not talk to them. Report and delete.

All three big US carriers run network-level scam blocking, and the free tiers kill known scam calls before your iPhone is even involved.

• T-Mobile Scam Shield. Free for every T-Mobile customer. Scam ID labels suspicious calls, and Scam Block stops them outright; turn it on in the T-Life app or just dial #662# from your phone.
• Verizon Call Filter. The free tier detects spam and auto-blocks the highest risk calls, but confirm it is enabled in the Call Filter app or your My Verizon account, since on some plans it sits idle until you do. The paid Plus tier adds caller ID and a personal block list for a few dollars a month per line.
• AT&T ActiveArmor. The free app blocks known fraud calls and labels suspected spam. The Advanced tier, around 7 dollars a month at this writing, adds caller ID, a VPN, and identity monitoring.

Our honest take: skip the paid tiers unless work requires caller ID on unknown numbers, because free network blocking plus iOS Call Screening covers the same ground. On a smaller prepaid brand, you usually inherit the basics of whichever big network it rides on; a quick search of your carrier's name plus scam blocking will confirm what is included.

The App Store is full of call and text blocking apps, and they plug into iOS through official hooks: a call blocker is switched on under Settings > Apps > Phone > Call Blocking & Identification, and a text filter is selected in Messages settings. The good ones maintain huge, constantly updated databases of scam numbers and catch calls that slip past everything above.

Who genuinely benefits: people still getting ten calls a day after the free layers, and anyone who must answer unknown numbers for work, like contractors or anyone job hunting, because these apps identify callers instead of just silencing them. For everyone else the free stack is enough, and our tested picks live in our roundup of the best security and privacy apps for iPhone.

Two things to weigh before subscribing. Cost: the useful ones run about 2 to 10 dollars a month after a short trial, and free tiers are usually crippled. Privacy: by design, a text filter reads messages from people who are not in your contacts, and a call blocker sees who calls you, so stick to established developers with a real privacy policy. A few of our favorite cleanup tools in the best utilities apps for iPhone guide come from the same trustworthy shops.

A quick tour of popular advice that underdelivers. The National Do Not Call Registry at donotcall.gov is free, takes two minutes, and is worth doing, but it only stops law-abiding telemarketers; criminals do not consult it. Calling a spammer back, or pressing 1 to be removed, confirms a live number and earns you more calls. Paid data-removal services shrink your footprint with data brokers over months, not weeks. And changing your number often backfires, since recycled numbers frequently arrive pre-loaded with the previous owner's spam.

Worth more than any of that is knowing this year's greatest hits on sight. The unpaid toll text, impersonating E-ZPass, SunPass, FasTrak and friends, threatening late fees unless you pay through a link. The missed package text pretending to be USPS or UPS. The wrong-number text that opens friendly and slow-walks you toward an investment pitch. The fake bank fraud alert. And the fake Apple support call about suspicious account activity. The defense is the same boring rule every time: never tap a link or call a number from an unexpected message; check in the official app instead, or type the website yourself. No real toll agency, bank, or government office takes payment in gift cards or crypto, and as Apple spells out in its guide to recognizing social engineering scams, Apple will never ask for your passcode, password, or a verification code. The less of your data floating around, the fewer lists you land on, so while you are in cleanup mode, our walkthroughs on locking down Google app privacy settings and private browsing with Brave on iOS are natural next steps.

Here is the whole plan as a checklist you can run right now:

1. Update first. Settings > General > Software Update, and install whatever iOS 26 update is waiting; the screening tools live there.
2. Calls. Settings > Apps > Phone > Screen Unknown Callers, set to Ask Reason for Calling, and confirm the carrier spam filter is on in the same screen.
3. Texts. Settings > Apps > Messages, turn on Screen Unknown Senders, and leave the spam filter on.
4. Carrier. Activate Scam Shield, Call Filter, or ActiveArmor for your network. Two minutes in the carrier app.
5. Registry. Add your number at donotcall.gov. Small win, but free.
6. Habits. Report Junk or forward to 7726 instead of replying, never tap links in unexpected texts, and block only the repeat offenders.

For the first week, peek at the unknown sender folder and the filtered call lists every day or two and tap Mark as Known for the real people. After that the system runs itself: your phone goes quiet, and the next fake toll bill becomes a 30-second report instead of a heart-rate spike. That is as close to winning this fight as anyone gets in 2026, and it costs nothing.
