What Are Scam Calls and Why Are They a Problem?

Scam calls, including robocalls and telemarketing, are automated or unsolicited calls designed to deceive recipients into providing personal information or money. They exploit the ease and low cost of making mass calls, leading to significant financial losses and privacy concerns.

How Can I Block Scam Calls on My Mobile Phone?

1. Use Robokiller to Block Scam Calls

Robokiller is a mobile app designed to block scam calls and texts. It utilizes a global database of known scammers and machine learning to identify and block unwanted calls before they reach you.
