Though carriers and governments try to reduce unwanted phone calls, it’s an uphill battle.Scammersandstalkersdon’t care about obeying the law, so they use a variety of methods to get around safeguards. In many cases, scammers aren’t even based in the country they’re targeting – that makes it difficult or impossible to throw them in prison.

If you have aniPhone, there are a variety of methods you’re able to use to screen phone calls. Some will simply save you the trouble of answering, while others will block calls outright.

5 Apple Intelligence features that still haven’t launched yet

Apple is being extremely cautious with its generative AI efforts.

How to screen calls with Live Voicemail

Simple and automatic

If you’re running iOS 17 or later, a feature called Live Voicemail is on by default, so as long as your iPhone is set to asupported country and language. Compatible languages currently include English, French, German, Spanish, Cantonese, Mandarin, Japanese, and Brazilian Portuguese.

You’ll see a real-time transcription on your lock screen as someone leaves voicemail, assuming an unwanted caller is patient enough for that. If you miss a live transcription, don’t worry – so long as you have Visual Voicemail active, you’ll see the same transcription alongside saved messages in the Phone app’s Voicemail tab.

How to silence all unknown callers

Be judicious with this one

A surefire way to block scammers and telemarketers is the Silence Unknown Callers option. Your iPhone will automatically block anyone you haven’t talked to before, making exceptions mainly for people in your Contacts app, numbers you’ve texted, and numbers shared in emails. If you dial an emergency line, the feature is temporarily disabled for 24 hours as a precaution.

Use the feature with caution since you could accidentally block critical calls from government agencies or job recruiters. However, if unwanted calls make your life a nightmare, it might still be worth using Silence Unknown Callers as long as you’ve added everyone you know to Contacts.

How to block specific phone numbers

The targeted approach

As you’d expect, you can block individual phone numbers. This isn’t as handy as you might think, though – it’s easy for determined callers to switch or spoof numbers. The option is best used against businesses that refuse to leave you alone.

The quickest way to block someone is right after an unwanted call:

You can also block people via the Contacts app, or by going toSettings > Apps > Phone > Blocked Contacts. That second option makes it easy to undo blocks if necessary.

How to screen calls using third-party apps

Your access may vary

For a while now, iPhones have allowed third-party apps to tackle automatic caller identification and blocking. I rely onHiya, which offers some basic features for free, like flagging suspect spam. Its full features are gated behind a paywall, unfortunately, and even then, they only work if you’re signed up with one of the big three US carriers (AT&T, T-Mobile, or Verizon). You may have to do some searching in the App Store to find an app that works with your carrier at a price you can afford.

The good news is that Apple has a limited ID service of its own, dubbed Business Connect ID, which is on by default and completely free. The main issue is that it’s restricted to companies verified by Apple, so it may miss some smaller businesses, and it certainly won’t pick out scammers and stalkers.
