SIM Swapping Scam: How to Protect Yourself from Phone Number Theft

SIM swapping, a type of cyber fraud, is on the rise, as evidenced by a recent case where victims lost a staggering $1.8 million. This scam works by tricking mobile carriers into transferring a victim's phone number to a fraudster's device. Once the number is transferred, the scammer can intercept text messages and phone calls, often gaining access to sensitive information needed to reset passwords and access bank accounts.

Protecting yourself from SIM swapping requires vigilance. Experts recommend setting up a PIN or password with your mobile carrier. This adds an extra layer of security, requiring the carrier to verify your identity before making any changes to your account. It's also crucial to be wary of phishing emails and suspicious phone calls that may attempt to gather personal information.

Another preventative measure is to use strong, unique passwords for all your online accounts. Enable two-factor authentication (2FA) whenever possible, using an authenticator app instead of SMS-based 2FA, as text messages can be intercepted in a SIM swap. Regularly monitor your bank and credit card statements for any unauthorized activity. By taking these steps, you can significantly reduce your risk of becoming a victim of SIM swapping.
