Your phone number can unlock your bank, email and social accounts.
Direct answer
SIM swap fraud happens when criminals persuade your mobile provider to transfer your number to a new SIM that they control. They then receive your texts and calls, including login codes, and can access your accounts. Protect yourself with a mobile account PIN, authenticator apps and by limiting personal information online.
Warning signs
- Sudden loss of signal on your phone.
- Alerts about password changes or logins you did not make.
- Provider messages about a SIM change you did not request.
Protect yourself
- Ask your provider about extra account security such as a PIN.
- Use an authenticator app or security key instead of SMS codes where possible.
- Do not post your phone number, birth date and address publicly.
- Be careful with phishing links.
If it happens
Contact your provider immediately, then your bank and email provider. Change passwords and report to authorities.
