How to Block Unknown Calls: A Guide for Everyday Users

Receiving unknown calls can be both disruptive and concerning. Fortunately, there are effective strategies to block these calls and safeguard your privacy.

Why Am I Receiving Unknown Calls?

Unknown calls often originate from telemarketers, scammers, or robocallers. These calls can be intrusive and sometimes deceptive, aiming to solicit personal information or money.

What Are the Risks of Unknown Calls?

Answering unknown calls can expose you to potential scams, identity theft, and unwanted solicitations. Some scammers use sophisticated tactics to appear legitimate, making it challenging to discern their true intentions.

How Can I Block Unknown Calls on My Phone?

For iPhone Users:

  1. Go to Settings.
  2. Tap on Phone.
  3. Select Silence Unknown Callers.

This feature sends calls from numbers not in your contacts directly to voicemail. However, it may also redirect important calls from unknown numbers to voicemail.

For Android Users:

  1. Open the Phone app.
  2. Tap the three-dot menu and select Settings.
  3. Choose Block numbers.
  4. Enable Block unknown callers.

This option blocks calls from unidentified numbers but might also block legitimate calls from unknown sources.

What Are the Limitations of Built-in Call Blocking Features?

While built-in features can reduce unwanted calls, they have limitations:

  • False Positives: Important calls from unknown numbers may be blocked.
