Protecting Your Phone Number from Unwanted Calls: A Comprehensive Guide

Receiving unwanted calls, such as spam and robocalls, is a common nuisance for many phone users. These calls can be disruptive and, in some cases, even dangerous. Fortunately, there are several effective strategies to protect your phone number and reduce these interruptions.

What Are Spam and Robocalls?

Spam calls are unsolicited communications, often from telemarketers or scammers, aiming to sell products or services. Robocalls are automated calls that deliver pre-recorded messages, frequently used for telemarketing or fraudulent purposes. Both types can be intrusive and pose security risks.

  1. Go to Settings > Phone.
  2. Toggle on Silence Unknown Callers.
  • Third-Party Apps: Applications like Truecaller can identify and block spam calls. After downloading from the App Store, grant the necessary permissions to enable call blocking. (techradar.com)
