What is a mobile phone porting or SIM swap scam?

A phone porting scam is when a cybercriminal transfers (ports) your mobile number from one provider to a different provider, or to a different SIM (a physical SIM card or an eSIM) on a device they control. 
 
Mobile phone porting is often the next step after a cybercriminal has accessed your personal information through other means, such as a phishing scam, which may allow them to answer any security questions your telecommunications provider might ask. 

This gives the criminals to access your security codes, including those from Bank First, so they can authorise transactions or change account details without your knowledge.  

Criminals may also use phone porting to gain control of email accounts, superannuation and government accounts, and your social media accounts, so they can access more of your personal information.

How do I know if my phone has been ported?

If you receive an unexpected text message from your mobile service provider advising that “you” have requested your number be ported to a different network provider, a criminal might be trying to port your phone. 

Another warning sign is if your mobile phone service is suddenly disconnected and showing “SOS only” where the telecommunications company name normally appears. This could mean your mobile phone number has been transferred to another provider without your permission. 

Keep an eye out for emails and notifications about new logins on different devices (that weren’t you). If you become locked out of your email or social media accounts, or you notice unauthorised transactions in your bank account, you may be a victim of phone porting. 

What to do if you suspect your phone has been ported

If your phone mobile service shows “SOS only” or “No Service” and doesn’t return quickly, contact your telecommunications provider to enquire why.
