In today's digital age, unsolicited calls are a common nuisance. To combat this, various solutions have emerged, including carrier call filtering, Apple's built-in call blocking, and third-party apps like Robokiller. This article delves into each option to help you make an informed choice.
What Is Carrier Call Filtering?
Carrier call filtering involves services provided by your mobile carrier to identify and block potential spam or fraudulent calls. Major carriers in the U.S. offer such services:
-
AT&T ActiveArmor: Offers a free version that blocks scam calls.
-
T-Mobile Scam Shield: Provides a free service to detect and block scam calls.
-
Verizon Call Filter: Offers a paid service with advanced spam detection features.
These services typically label suspected spam calls, allowing users to decide whether to answer or block them. However, they may not be as effective in completely blocking unwanted calls.
How Does Apple's Call Blocking Work?
Apple's built-in call blocking feature, known as "Silence Unknown Callers," sends calls from unknown numbers directly to voicemail. This feature is accessible through the iPhone's settings:
-
Open the Settings app.
-
Tap on Phone.
-
Select Silence Unknown Callers.
While this method effectively silences unsolicited calls, it also means you might miss important calls from unknown numbers, such as from doctors or delivery services.
What Is Robokiller and How Does It Work?
Robokiller is a third-party app designed to block spam calls by using AI-powered answer bots that engage with scammers, wasting their time and deterring future calls. It offers features like:
-
Spam Call Blocking: Automatically identifies and blocks spam calls.
-
Answer Bots: Engages with scammers to waste their time.
-
Customizable Blocking: Allows users to set preferences for blocking calls.
Robokiller is available for both iOS and Android devices. However, it requires a subscription, with plans starting at $4.99 per month. (parade.com)
