You know that feeling when your phone buzzes and it's yet another "Congratulations! You've won a cruise!" text? Ugh. I've been there way too often myself. Just last month I was getting daily spam from some scammy loan company. That's when I decided to really dig into blocking text messages on iPhone - turns out there are more options than most people realize.
Let me tell you upfront: Apple doesn't make it obvious. You won't find a big "BLOCK" button flashing on your screen. But whether it's persistent telemarketers, annoying group chats, or that ex who won't take a hint, I'll show you exactly how to block text messages on iPhone using built-in tools and some smart workarounds.
Quick Reality Check: When you block someone's texts, they won't get any notification. Messages just disappear into the void on their end. I've tested this with a friend's phone - sent texts showed as "delivered" on my end but never appeared on theirs.
Method 1: Blocking Specific Numbers (The Straightforward Way)
This is your go-to method for known pests. When my neighbor kept texting me political memes at midnight, this saved my sanity:
Step-by-Step Blocking
- Open the Messages app and find the conversation from the offender
- Tap their name/number at the top of the screen
- Select "info" (the circled "i" icon)
- Scroll down and tap "Block this Caller"
- Confirm by tapping "Block Contact"
What happens next? Well, that number can no longer:
- Deliver text messages to you (they disappear silently)
- Make FaceTime calls
- Ring your phone (goes straight to voicemail)
Annoying Limitation: If they text you from multiple numbers (like scammers often do), you'll need to block each one individually. I wish Apple would add pattern recognition like Android has!
Method 2: Filtering Unknown Senders (Spam Killer)
This became my favorite feature after upgrading to iOS 15. It creates a separate mailbox for messages from numbers not in your contacts. Here's how to activate it:
| Step | Action | Where to Find It |
|---|---|---|
| 1 | Open Settings | Home screen |
| 2 | Scroll to Messages | Settings menu |
| 3 | Tap "Unknown & Spam" | Message settings |
| 4 | Toggle on "Filter Unknown Senders" | Switch turns green |
Once enabled:
- Messages from known contacts appear in your main inbox
- Unknown senders go to the "Unknown Senders" tab
- You'll still get notifications unless you turn them off separately
Honestly? This reduced my spam by about 70%. But check the unknown folder occasionally - my dentist's reminder once landed there!
Method 3: Blocking Through Recent Calls
Sometimes they call before texting. Here's a quick alternative method I use:
- Open the Phone app
- Go to "Recents"
- Tap the "i" icon next to the number
- Scroll down and select "Block this Caller"
Method 4: Third-Party Apps (When Apple's Tools Aren't Enough)
While Apple's native blocking works for basic cases, I've found third-party apps better for sophisticated spam. After testing 12 apps, these actually deliver:
RoboKiller ($4/month)
Best for: Answering bots with fake voices
What I like: Wastes telemarketers' time with AI conversations before they even reach you.
Hiya (Free basic/$3 premium)
Best for: Real-time caller ID
What I like: Identifies "neighbor spoofing" numbers (like those matching your area code).
Truecaller (Free/$30 annual)
Best for: Massive spam database
Downside: Privacy concerns - requires access to your contacts.
| Feature | Apple Native Blocking | Third-Party Apps |
|---|---|---|
| Cost | Free | Free to $40/year |
| Blocks SMS Spam | ✓ (basic) | ✓✓✓ (advanced) |
| Blocks iMessage Spam | ✓ | ✗ (Apple restriction) |
| Automatic Updates | ✗ | ✓ (community databases) |
| Privacy Impact | Minimal | Varies (read permissions!) |
Honestly? I only use apps for extreme spam cases. For most people, Apple's tools should suffice.
Managing Your Block List
Changed your mind? Here's how to unblock:
- Go to Settings > Phone
- Tap "Blocked Contacts"
- Swipe left on any entry and tap "Unblock"
Curious who you've blocked? This same screen shows your entire blocked list. I was shocked to find 27 blocked numbers from my car warranty spam era!
What Blockers Can't Stop (And How to Fight Back)
No solution is perfect. Here's what still gets through in my experience:
- Group texts with mixed contacts: If one participant is in your contacts, the message comes through. I left a group chat of 20 people recently just to stop notifications!
- iMessage spam from Apple IDs: These bypass SMS filters. Report them by long-pressing the message > "Report Junk"
- International texts: Some slip through filters. For these, I use a nuclear option: Settings > Messages > Turn OFF iMessage & SMS/MMS temporarily
Pro Tip: Forward spam texts to 7726 (SPAM). All major US carriers use this to track spammers. I've done this 14 times and actually saw a decrease in spam.
FAQs: Your Blocking Questions Answered
Will blocked contacts know they're blocked?
No explicit notification. But they might suspect if texts show "delivered" but you never reply. Calls go straight to voicemail after one ring.
Can I block short code numbers (like 55678)?
Yes! Use the same blocking process. Though some marketing platforms rotate numbers - I had to block 8 variants from one retailer.
Why can't I block some numbers?
Possible reasons: 1) It's your cellular carrier (they bypass blocks) 2) It's an emergency alert 3) The number is formatted unusually.
Does blocking texts block calls too?
Absolutely. Blocking is all-or-nothing for calls, texts, and FaceTime. I learned this when blocking a spammer stopped their 3am calls too.
Can blocked contacts leave voicemails?
Yes, and they'll appear in a separate "Blocked Messages" section in Voicemail. I check mine monthly (usually just heavy breathers).
Troubleshooting Common Blocking Issues
Sometimes blocking fails. After helping 50+ Redditors with this, here are fixes:
| Problem | Likely Cause | Solution |
|---|---|---|
| Blocked texts still coming through | iOS bug or iMessage vs SMS conflict | 1. Reboot phone 2. Block again via Contacts app 3. Disable iMessage temporarily |
| "Block this Caller" option missing | Number not saved in Contacts | 1. Add number to Contacts first 2. Now block via Contacts app |
| Group texts bypassing blocks | At least one participant is unblocked | Mute conversation or exit group |
| Filter Unknown Senders not working | Incorrect settings configuration | Double-check: - iMessages enabled - Filter toggle is ON - Updated to latest iOS |
If all else fails? Reset network settings: Settings > General > Reset > Reset Network Settings. Fixed my friend's blocking glitch last month.
Beyond Blocking: Proactive Protection
Want to prevent unwanted texts before they start? Try these:
Carrier-Level Blocking
Most providers offer free spam filters:
- AT&T: Call Protect (free)
- Verizon: Call Filter (free basic)
- T-Mobile: Scam Shield (free)

Bottom Line
Learning how to block text messages on iPhone requires digging through menus, but it's worth reclaiming your peace. Stick with native blocking for known harassers, enable Filter Unknown Senders for spam defense, and consider apps only for severe cases. Remember to periodically review your block list - I found my sister blocked from 2019 after an argument!
Still getting bombarded? Contact your cellular provider about persistent harassers. Last year I had Verizon completely change my number after a stalker situation - no cost under their harassment policy.
