Can someone hijack your phone number? Yes, phone number hijacking, also known as SIM swapping or port-out scamming, is a real threat. This occurs when someone fraudulently transfers your phone number to another SIM card, potentially gaining access to sensitive accounts linked to your phone number. Understanding how this happens and how to protect yourself is crucial.
What Is Phone Number Hijacking?
Phone number hijacking involves unauthorized access to your phone number, often through SIM swapping. This is when a scammer tricks your mobile carrier into transferring your number to a new SIM card they control. Once they have your number, they can intercept calls and texts, including two-factor authentication codes, potentially accessing your bank accounts, email, and social media.

- Gathering Information: Scammers collect personal information through phishing, social engineering, or data breaches.

- Activating a New SIM: Your number is transferred to a SIM card they control, giving them access to your calls and texts.
Why Is Phone Number Hijacking Dangerous?

How Can You Protect Yourself from Phone Number Hijacking?
