To prevent SIM card swapping, you'll need to be vigilant about the information you share and how passwords are stored. The FBI recommends the following precautions:

• If you're contacted by someone claiming to be from a telecom company, don't volunteer personal information, like your PIN or phone number. Instead, verify the call by dialing the customer service line of your mobile carrier.
• Avoid posting personal information online, such as your phone number or address. This can include photos shared on social media, too. A good example of this would be to avoid posting a picture of your vaccination card, which includes your date of birth.
• Use a variety of passwords to access online accounts and change them often.
• Embrace strong multi-factor authentication methods such as biometrics, physical security tokens or standalone authentication applications to access online accounts.
• Don't store passwords, usernames or other information for easy login on mobile device applications.
• Don't advertise information about financial assets, including ownership or investment of cryptocurrency, on social media websites and forums.

If your phone has been cut off and you think you might be a victim to a SIM swap, immediately notify your phone provider and change the passwords to your online accounts. You can report the scam to the FBI's Internet Crime Complaint Center at www.ic3.gov.
