How to Identify and Block Spam Calls While Allowing Contacts Through

Spam calls can be a significant nuisance, disrupting your day and potentially exposing you to scams. Fortunately, there are effective strategies to identify and block these unwanted calls while ensuring that calls from your contacts come through uninterrupted.

1. Utilize Built-in Features on Your Smartphone

iPhone Users:

  • Silence Unknown Callers: This feature silences calls from numbers not saved in your contacts, sending them directly to voicemail. To enable it:

  • Go to Settings > Phone > Silence Unknown Callers and toggle it on. (support.apple.com)

  • Call Identification Apps: iPhones support third-party apps that can identify and block spam calls. To set this up:

  • Download a reputable call identification app from the App Store.

  • After installation, go to Settings > Phone > Call Blocking & Identification and enable the app. (support.apple.com)

Android Users:

  • Caller ID & Spam Protection: This feature provides information about incoming calls and warns you about potential spam. To activate it:

  • Open the Phone app.

  • Tap the three-dot menu > Settings > Caller ID & Spam and toggle on See caller ID & spam. (support.google.com)

  • Call Screening: On certain Android devices, you can screen calls to filter out spam:

  • Go to Settings > Call Screen and enable Automatically Screen Calls. (howtogeek.com)

2. Report and Block Unwanted Calls

  • iPhone: To block a specific number:

  • Open the Phone app, tap the Info icon next to the number, and select Block this Caller. (support.apple.com)

  • Android: To report a spam call:

  • Open the Phone app, tap the Recents tab, select the call, and choose Block or Report spam. (support.google.com)

3. Consider Third-Party Call Blocking Apps

If built-in features are insufficient, third-party apps can offer enhanced protection:

  • Robokiller: This app identifies and blocks spam calls, allowing you to customize your preferences.

  • Truecaller: Offers a comprehensive database of known spam numbers and provides real-time alerts.

4. Stay Vigilant and Educate Yourself

  • Recognize Common Spam Tactics: Be aware of unsolicited calls claiming to be from banks, government agencies, or offering too-good-to-be-true deals.

  • Avoid Sharing Personal Information: Never share sensitive information over the phone unless you're certain of the caller's identity.

By implementing these strategies, you can significantly reduce the number of spam calls you receive while ensuring that important calls from your contacts get through.
