How to block scam texts and emails on iPhone

Turn on iPhone filtering, avoid fake links, report scam texts, and add a scam focused layer for SMS and email protection.

iPhone settings screen for message filtering

If scam texts are the problem, do three things today:

  1. Turn on Apple's built in filtering.
  2. Stop using links inside bank, delivery, tax, account, or payment messages.
  3. Add a filter that is built for scams, not only for messy inbox cleanup.

iPhones with iOS 26 have newer tools to help screen unknown senders, spam, and blocked contacts. If your iPhone cannot run iOS 26, Apple still gives you basic blocking and filtering tools, but they are not the same as a dedicated scam layer.

That is the gap this article is about.

Turn on Apple's tools first

Apple documents three useful controls for iPhone users:

Use them. They remove some noise and make obvious repeat scams easier to ignore.

On iOS 26, Apple has also moved more spam and unknown sender handling into clearer folders and controls. That helps. It is a good first layer, especially for people who mainly get random spam from numbers they do not know.

But scammers do not always behave like random strangers.

Why unknown sender filtering can fall short

A scam can appear to come from a sender you recognize or a situation that makes sense.

Examples:

MessageWhy it gets past your guard
"Your bank account is locked"You really do have that bank
"Your package needs a delivery fee"You were waiting for an order
"Your child changed numbers"Family messages are emotional
"Your tax invoice is attached"The email includes your real name or company
"A new login was detected"You have seen real security alerts before

The problem is not only who sent it. The problem is the story, the link, the timing, and the request.

The open it yourself rule

For bank, delivery, tax, school, email, Apple ID, PayPal, Microsoft, or payment messages:

  1. Do not tap the link.
  2. Do not call the number in the message.
  3. Open the official app yourself.
  4. Type the website yourself.
  5. Call the number on your card, bill, account page, or official website.

This sounds simple because it is. It breaks the scammer's route.

The message may be fake, but the official app is still the official app.

Treat email and SMS as one scam path

People separate texts and emails. Scammers do not.

A fake bank SMS may lead to an email. A fake invoice email may lead to a text. A fake delivery email may ask you to confirm a phone number. A fake tech support email may ask you to call.

Watch for:

If the message makes you feel rushed, slow down on purpose.

Report the message

Forwarding spam texts to 7726, which spells SPAM, is supported by many carriers in the United States and Canada. Apple also lets users report junk in Messages when the option appears.

For fraud reports:

RegionWhere to start
United StatesFTC at ReportFraud.ftc.gov, your bank, and your carrier through 7726 where supported
CanadaCanadian Anti-Fraud Centre, your bank, and 7726 where supported
MexicoYour bank first, then CONDUSEF guidance and local cyber police channels
BrazilYour bank first. For Pix, ask about the Mecanismo Especial de Devolução
UAEYour bank first, then Dubai Police, Abu Dhabi Police Aman service, or the official cybercrime channel for your emirate

The setup I would give a family member

If someone asked me to make their iPhone safer in ten minutes, I would do this:

  1. Turn on unknown sender filtering.
  2. Save bank, school, doctor, and family numbers.
  3. Put the bank app on the home screen.
  4. Teach the open it yourself rule.
  5. Forward clear spam to 7726 where supported.
  6. Add a scam filter if they receive bank, delivery, tax, or family emergency messages often.

That last point matters for older iPhones too. If a device cannot use the newest iOS 26 filtering, the person still deserves help before a scam reaches the tap.
