How to Block Unknown Calls Without a Subscription: A Simple Guide

Unwanted calls from unknown numbers can be a significant nuisance, disrupting your daily life and potentially exposing you to scams. While many call-blocking apps require subscriptions, there are effective methods to block these calls without incurring additional costs.

Understanding the Challenge of Blocking Unknown Calls

Blocking calls from unknown numbers is challenging because legitimate callers may also be unknown to you. Traditional call-blocking apps often rely on databases of known spam numbers, which can miss new or spoofed numbers. Additionally, some apps may require subscriptions or complex setups, making them less accessible.
