Protecting Your Personal Phone Number from Unwanted Calls

Protecting Your Personal Phone Number from Unwanted Calls

Receiving unwanted calls on your personal phone can be both frustrating and intrusive. Fortunately, there are several effective strategies to protect your number from spam and robocalls.

Why Are Unwanted Calls So Common?

Unwanted calls, including spam and robocalls, have become increasingly prevalent due to the low cost and ease of making automated calls. Scammers often use caller ID spoofing to disguise their identity, making it challenging to identify and block these calls. In 2025, Americans received over 52.5 billion robocalls, averaging roughly 13–15 spam calls per person per month. (antivirus.com)

How Can I Block Spam Calls on My iPhone?

Apple provides built-in features to help manage unwanted calls:

  • Silence Unknown Callers: This feature silences calls from numbers not in your contacts, recent calls, or Siri suggestions. To activate it:
  1. Go to Settings > Phone.
  2. Toggle on Silence Unknown Callers.

While this method effectively reduces interruptions, it may also silence calls from legitimate contacts not saved in your phone. (techradar.com)

How Can I Block Spam Calls on My Android Phone?

Android devices offer several options to block unwanted calls:

  • Google Phone App: Many Android phones come with the Google Phone app, which includes a built-in spam filter. To enable it:
  1. Open the Phone app.
  2. Tap the three-dot menu > Settings > Caller ID & Spam.
  3. Toggle on See caller & spam ID and Filter spam calls.

This feature helps identify and block potential spam calls automatically. (whocalledus.net)
