How to Block Scam Calls on Your AT&T iPhone

Scam calls are a persistent nuisance for iPhone users, often leading to unwanted interruptions and potential security risks. Fortunately, there are several effective methods to block these calls on your AT&T iPhone.

What Built-in Features Can Help Block Scam Calls?

Silence Unknown Callers

iOS offers a feature called "Silence Unknown Callers," which sends calls from numbers not in your contacts directly to voicemail. To enable this:

  1. Open Settings.
  2. Scroll down and tap on Phone.
  3. Toggle on Silence Unknown Callers.

This feature helps reduce interruptions from unknown numbers, though it may also silence calls from legitimate sources not saved in your contacts. (makeuseof.com)

Call Blocking and Identification

iOS also allows you to block specific numbers:

  1. Open the Phone app.
  2. Go to the Recents tab.
  3. Tap the information icon ("i") next to the number you want to block.
  4. Scroll down and select Block this Caller.

This method is effective for blocking known scam numbers but requires manual input. (makeuseof.com)

AT&T offers a service called ActiveArmor, which provides advanced call protection features:

This action notifies AT&T of potential scam numbers, aiding in the enhancement of their call protection services. (about.att.com)

What Are the Limitations of These Methods?

While these features and apps are effective, they may not block all scam calls. Some legitimate calls from unknown numbers might be missed, and scammers may use different numbers to bypass filters. Regularly updating your iOS and any call-blocking apps can help maintain optimal protection.

By utilizing these built-in features and services, you can significantly reduce the number of scam calls on your AT&T iPhone, enhancing your overall mobile experience.
