How to protect yourself from SIM swaps

What is a SIM swap?

A SIM swap happens when someone takes control of your mobile number by convincing your provider to move it to a new SIM card they control.

They usually pretend to be you and use personal details like your date of birth or address to pass security checks.

Once they take over your number, they can receive your calls and texts — including security codes used to log in to your bank, email or social media accounts.

You might first notice something is wrong when your mobile service suddenly stops working.

How to protect yourself

Scams are common, but there are things you can do to reduce your risk.

Be careful with your personal information

• Don’t share your full name, date of birth, address or phone number publicly online
• Limit what others can see on social media or dating profiles
• Keep your mail secure — a locked letterbox can help

Watch out for scams

• Don’t click links in unexpected texts or emails
• Don’t respond to messages claiming you’ve won a prize or need to act urgently
• Never give passwords or verification codes to someone who contacts you
• Hang up if a caller asks for remote access to your computer

Add extra security where you can

• Ask your telco if you can add a password or PIN to your account
• Use strong, unique passwords for your accounts
• Turn on multi-factor authentication (using an app where possible)
