Cybercriminals now use mobile networks to carry out scams. One of the most dangerous is the SIM swap scam, where they steal phone numbers to access sensitive information.
This scam can lead to financial theft and identity fraud. By learning how SIM swap scams work and how to respond, you can better protect your personal information and finances.
What is a SIM SWAP Scam?
A SIM swap scam or SIM hijacking happens when criminals trick your mobile provider into transferring your phone number to a new SIM card they control.
Once they have your number, they can access your text messages, emails, and accounts that rely on SMS for authentication.
These scams are especially dangerous because many financial and social media accounts use two-factor authentication (2FA) through text messages, which allows scammers to reset their passwords and take over their accounts.
If successful, you lose access to your phone number, and the scammer starts receiving your calls and texts, which include one-time passwords (OTPs) and account recovery codes.
How Does SIM SWAP Scam Work?
Scammers start by collecting your personal information, like your name, address, phone number, and security answers. They get this information through phishing, leaked data, or by tricking you directly. They use these details to pretend to be you when contacting your phone carrier.
Next, the scammer calls your mobile provider, claiming they lost their phone or SIM card. They ask to move your phone number to a new SIM card they control, which uses the information they collected to convince the provider they are you.
Once the mobile provider approves the request, your SIM card stops working, and the scammer now gets all your calls and texts, which include important verification codes.
With access to your phone number, the scammer intercepts these codes sent via SMS for accounts like your bank, email, and social media. This lets them reset your passwords and lock you out of your accounts.
After gaining control, scammers can steal money from your bank, take personal data, and even impersonate you to commit more fraud. They empty your accounts, access your cryptocurrency, or carry out other fraudulent activities in your name.
What To Do If You Fall For SIM SWAP Scam?
If your phone stops working or you suspect a SIM swap scam, act fast to limit the damage.
- Secure Your Phone Number: Some mobile providers offer extra security measures like PINs or passcodes to prevent unauthorized SIM swaps. Activate these options to add more protection to your phone number.
- Contact Your Mobile Carrier Right Away: The moment you notice something is wrong, call your mobile provider. Ask them to block any SIM swap tries and restore your service. Let them know about the scam so they can secure your account.
- Protect Your Online Accounts: Change the passwords for all accounts connected to your phone number, starting with banking and email accounts. Create strong, unique passwords for each one. Switch from SMS-based two-factor authentication to app-based options like Google Authenticator or YubiKey for extra security.
- Check Your Bank Accounts: Watch your bank statements and online transactions closely for unusual activity. If you spot something suspicious, contact your bank immediately to prevent further losses.
- Report the Scam: File a report with local law enforcement and agencies like the Federal Trade Commission (FTC). These reports can help with investigations and may be necessary for recovering any financial losses.
