How to protect yourself from SIM swap scams

In today's digital age, our phone numbers have become a crucial part of our identity. Unfortunately, this has given rise to a dangerous form of fraud known as SIM swap scams. This article will guide you through understanding and protecting yourself from this threat. 

What is a SIM swap scam

A SIM swap scam, also called SIM swapping or SIM swap fraud, occurs when a malicious actor convinces your mobile carrier to transfer your phone number to a new SIM card they control. This gives them access to your calls, text messages, and potentially much more. 

Why is it dangerous? 

Once scammers control your phone number, they could intercept your SMS one-time passwords (OTPs) used for two-factor authentication, allowing them to: 

1. Access your bank accounts and make unauthorized transfers 

2. Take over your social media profiles 

3. Gain entry to other online accounts linked to your phone number
