Effective Strategies to Reduce Repeat Spam Calls on Your iPhone

Spam calls are a persistent nuisance for iPhone users, often disrupting daily routines and compromising privacy. Fortunately, there are several effective strategies to reduce these interruptions.

How Can You Silence Unknown Callers on Your iPhone?

iOS offers a built-in feature called "Silence Unknown Callers" that automatically silences calls from numbers not saved in your contacts, recent calls, or Siri Suggestions. To enable this feature:

  1. Open the Settings app.
  2. Tap Phone.
  3. Select Silence Unknown Callers.
  4. Toggle the switch to On.

This setting ensures that calls from unfamiliar numbers are sent directly to voicemail without ringing, allowing you to review them at your convenience. (support.apple.com)

If you receive spam calls from specific numbers, you can block them manually:

  1. Open the Phone app.
  2. Go to the Recents tab.
  3. Tap the Info icon next to the number you want to block.
  4. Scroll down and tap Block this Caller.

This action prevents the blocked number from contacting you via calls, messages, or FaceTime. (support.apple.com)

How Can You Utilize Carrier Services to Block Spam Calls?

Many carriers offer services to identify and block spam calls:

  • Verizon: Provides a service called Call Filter that identifies potential spam calls.
  • T-Mobile: Offers Scam Shield, which detects and blocks scam calls.

To activate these services, contact your carrier or visit their website for instructions. (howtogeek.com)
