Block SMS on iPhone: Stop unwanted messages in 7 easy steps

Blocking spam messages: simpler than you think

Another spam text message. Your iPhone vibrates, your AirPods pause your music. Yet another person trying to lure you in with "free" prizes or dubious links. Your privacy feels like an open door anyone can walk through.

Blocking seems like the solution, but most people don't do it. They think it's too complicated. They're afraid of accidentally blocking important numbers. However, here's the twist: blocking text messages on your iPhone is ridiculously simple —seven taps and you're done.

The real problem? People don't block enough, not too many. They tolerate the same annoying senders for years because they think unblocking them is a nightmare. Spoiler alert: it literally takes two seconds. With the right tools and this approach, you can regain your peace of mind in five minutes.

The reality of spam messages on your iPhone

You know the feeling: just when you're concentrating on your work or enjoying a quiet moment, another unwanted message arrives. Spam text messages aren't just annoying; they also pose a serious privacy risk. Phishing scams, fake link scams, and identity theft often start with a seemingly innocent message.

The good news? Your iPhone has built-in features that effectively address this problem. No extra apps needed, no technical expertise required. Just seven simple steps that anyone can follow.

The 7 Steps to Block Text Messages

Step 1: Open the Messages app

Start by opening your default Messages app. This green app with the speech bubble is usually on your home screen.

Step 2: Find the disruptive conversation

Scroll through your messages until you find the conversation with the sender you want to block. This can be a phone number or a name if the contact is already on your phone.

Step 3: Open the conversation

Tap the conversation to open it in full. You'll now see all messages from that sender.

Step 4: Tap on the contact details

At the top of the screen, you'll see the sender's name or phone number. Tap this to access more options.

Step 5: Select 'info'

A new menu will appear. Select the small "i" icon or the text "info." This will open the contact details.

Step 6: Find the blocking option

Scroll all the way down on this screen. At the bottom, you'll find various options for this contact.

Step 7: Activate 'Block this caller'

Tap this red text and confirm your choice. From now on, you will no longer receive messages, phone calls, or FaceTime calls from this number.

Manage blocked numbers

It happens that you accidentally block the wrong number, or you want to contact them again later. Unblocking is just as easy:

  1. Open Settings on your device
  2. Scroll to 'Phone'
  3. Select 'Blocked Contacts'
  4. Swipe the number to the left
  5. Tap 'Unblock'

You'll immediately see an overview of all blocked numbers. This is handy for periodically checking that everything is still correct.

Preventive measures against spam

Filter unknown senders

iOS offers a smart feature to automatically filter messages from unknown numbers. Go to Settings > Messages and enable "Filter Unknown Senders." These messages will then appear in a separate tab without notifications.

Report spam to providers

Many providers have special numbers where you can report spam. Forward the message to this service. They can take action against the sender and protect others.

Share your number consciously

The best protection starts with prevention. Be selective about where you leave your phone number. Online forms, contests, and free services often sell your data to advertisers.

Frequently asked questions

Does the blocked sender know that I have blocked them?
No, the sender won't receive a notification. To them, it will appear as if the messages are being sent normally. They just won't reach you.

Can I block entire categories?
Apple doesn't offer an option to block all international numbers, for example. You have to block numbers individually. You can, however, use third-party apps for more advanced filters.

Does this also work for iMessage?
Yes, this method will block both regular SMS and iMessage messages from the number in question.

When blocking isn't enough

Sometimes spammers keep coming back with new numbers. In that case, you might consider:

  • Changing your phone number (last resort)
  • A second number to use for online activities
  • Set stricter privacy settings on social media

Your privacy deserves protection. This approach will help you regain control over your message list. It'll only take five minutes, but it'll give you months of peace of mind. Stop tolerating what irritates you. Take action and block those unwanted messages today.

Conclusion: stop tolerating spam

So, blocking spam messages on your iPhone isn't rocket science. Seven taps and you're back to your peace of mind. Most people let the same numbers bother them for years, even though the solution is so simple.

Start cleaning up your message list today and activate that unknown sender filter right away. Your refurbished iPhone has all the tools you need. No hassle with extra apps, no technical knowledge required. Just do it. Your privacy and peace of mind are worth it.
