Account security: Boost your cellphone’s account security with a unique, strong password and strong security questions and answers that only you know.And remember, your bank, cable provider, credit card company, or other service providers won’t ask for your personal or financial information through an email message. Don’t click on links in email messages from people you don’t know. Online behavior: Beware of phishing emails and other ways attackers may try to access your personal data to help them convince your bank or cell phone carrier that they are you.Fortunately, there are ways in which you, and your service providers, can help protect against becoming a victim of SIM swap fraud.
