What Is SIM Swap Fraud?

Imagine this: You’re walking down Church Street, and out of nowhere, your phone stops working. No calls. No texts. No access to your accounts. It’s more than just a frustrating inconvenience—it could be the first sign of SIM swap fraud.

What Is SIM Swap Fraud?

SIM swap fraud is a sneaky, high-stakes scam in which fraudsters take over your phone number by convincing your mobile carrier to activate a new SIM card in their device instead of yours. Once they succeed, they intercept your calls and texts—and, more dangerously, your security codes.

These codes are often the key to your most sensitive accounts, like online banking, email, and social media. For Vermont residents who rely on digital tools for everything from checking your credit union balances to managing local business accounts, this kind of fraud can have serious consequences.

A Quick Note on SIM Cards

Your SIM card (Subscriber Identity Module) is the small chip in your phone that allows you to make calls and send texts. Without it, your phone can only connect to Wi-Fi—no cell service, no texts, no security codes.

How the Scam Works

Here’s how it typically plays out:

  1. Data collection: Scammers gather personal information through phishing, malware, or social media.
  2. Impersonation: They contact your carrier, claiming to be you, and request a new SIM card activation.
  3. Control: Once activated, all your calls and texts go to the scammer’s device.

Why It’s So Dangerous

With 2FA codes rerouted, scammers can access your financial accounts, lock you out of your email, or even drain your checking account—often before you realize what’s happening.

In 2021 alone, the FBI reported over $68 million in SIM swap fraud losses. And the trend is rising, with reports up over 400% since 2018. This isn’t just a big-city problem—it can happen anywhere, including right here in Vermont.

Even high-profile figures have been affected. Twitter’s former CEO, Jack Dorsey, was famously SIM-swapped using information found on social media to bypass security questions.  High-profile cases like Dorsey’s grab the headlines, but here in Vermont, SIM swap fraud can hit anyone from small business owners to college students and everyone in between.

Warning Signs to Watch For

If something feels off, trust your instincts. These signs could indicate a SIM swap:

  • You suddenly can't make calls or send texts.
  • Your carrier notifies you of SIM activity from a different device.
  • You’re locked out of your accounts.
  • You notice suspicious or unauthorized transactions.

Smart Tips to Protect Yourself

Staying safe doesn’t require tech wizardry—just a little preparedness:

  • Use strong, unique passwords and change them regularly.
  • Don’t click suspicious links or respond to unexpected emails or texts.
  • Limit what you share online—even your pet’s name can be used to guess a security question.
  • Set up a PIN or passcode with your mobile carrier for added protection.
  • Use an authentication app (like Google Authenticator) instead of text-based 2FA.
  • Enable account alerts with your financial institutions and cell provider.
  • Consider behavioral analysis tools—some credit unions and banks use them to flag compromised devices.
  • Expect call-back verifications from organizations when something looks off—that’s a good thing.

Stay Vigilant

SIM swapping is a serious threat, but by adding layers of protection, you can better safeguard your accounts and identity. By adding a few simple layers of protection and knowing what to look out for, you can protect your identity and your financial well-being.
