iPhone Call Spam Screening: How to Block Robocalls and Junk Texts
If you're overwhelmed by robocalls and spam texts, you're not alone. According to spam analytics firm YouMail, U.S. consumers received an estimated 54.5 billion robocalls in 2024, or about 165 calls per second. Spam texts are just as bad — RoboKiller reports that Americans got 94 billion spam texts last year, a 12% increase from 2023.
Fortunately, Apple’s iPhone spam screening tools and third-party apps can help you regain control over your phone.
Why Spam Calls and Texts Are Surging
-
Scammers are getting smarter. Many spam calls now spoof local area codes or even real business numbers to trick you into answering.
-
Text spam is easier and cheaper. A single scammer can send thousands of phishing texts (aka "smishing") in seconds.
-
Consumer losses are rising. The FCC reports U.S. consumers lost over $10 billion to phone scams in 2023, with the average loss per incident over $800.
Built-in iPhone Features That Block Spam
1. Silence Unknown Callers
This feature, available in iOS 13 and later, automatically silences numbers not in your contacts. Calls go straight to voicemail, helping you avoid unwanted interruptions.
How to enable:
-
Settings > Phone > Silence Unknown Callers > Toggle ON
2. SMS Filtering
In Settings > Messages, toggle Filter Unknown Senders to push texts from unknown numbers into a separate tab — reducing phishing risk.
3. Report Junk
When you receive a suspicious message in iMessage, Apple gives you the option to “Report Junk”. This helps train Apple’s system to detect and block spam more effectively.
Third-Party Call and Text Blocking Apps
iPhones allow third-party apps to block calls and filter messages. These apps maintain live databases of known spam numbers and auto-block suspicious activity.

| AT&T | ActiveArmor | ✅ | Threat level alerts, reverse lookup |
| T-Mobile | Scam Shield | ✅ | Number masking, voicemail-to-text |
