SIM-Swap Scams: What You Need to Know
SIM-swap scams are a dangerous type of fraud where scammers take control of your mobile phone number to bypass two-factor authentication and access your personal accounts. By tricking mobile carriers into switching your number to a new SIM card, scammers can intercept texts, calls, and sensitive information, leading to financial loss and identity theft.

How SIM-Swap Scams Work
SIM-swap scams are a modern twist on identity theft. In this type of scam, fraudsters gather personal information about you—sometimes from social media, data breaches, or phishing attempts—and use it to impersonate you when contacting your mobile provider. By convincing the provider to transfer your phone number to a new SIM card that they control, the scammer essentially “swaps” your SIM card.
Once they have control of your phone number, they can intercept calls and text messages, including those used for two-factor authentication (2FA). This allows them to bypass security measures on your bank accounts, email, social media, and more. For instance, if your bank sends you a text message with a one-time password, the scammer receives it instead and can then access your account.

Why Do People Fall for SIM-Swap Scams?
SIM-swap scams succeed because they exploit the trust you have in your mobile provider and the convenience of mobile communications. When scammers contact your provider with enough of your personal details, they can often convince the carrier to activate a new SIM card. Many people don’t expect that their mobile number—something they rely on daily—could be hijacked.
The scam is particularly insidious because it can occur without any immediate signs on your device. You might suddenly lose service or notice unusual activity in your online accounts before realizing what has happened. This delayed discovery gives scammers a head start in accessing your sensitive information.

The Mindset Behind SIM-Swap Scams
At its core, a SIM-swap scam is all about exploiting trust and convenience. Scammers know that your mobile phone number is the key to many of your online accounts. By convincing your mobile provider that they are you, they bypass many of the security measures designed to protect you. Their approach is not primarily technological—it’s rooted in social engineering. They use gathered personal data and persuasive tactics to manipulate customer service representatives into making the switch.
People fall for these scams because they often don’t suspect that something as everyday as a phone number could be at risk. The combination of trust in the mobile system and the sophistication of the scammers’ methods leaves many unaware until it’s too late.
