Identity theft and cybercrime support network IDCare is warning Aussie phone users to be aware that when their phone enters SOS-only mode, it may not be because of lack of reception or a network outage.
It could also be a sign that someone is attempting to illegally port your number, especially if your phone doesn’t exit SOS mode when you move into different coverage areas.
Unauthorised mobile porting is “when a criminal contacts a different telephone provider, sets up an account with them and requests to have your number brought over from your current provider,” IDCare says.
Many people use mobile numbers as an added layer of security for accounts like online banking, emails and social media accounts – for example, entering a code that was texted to you to log in somewhere, or using a text prompt to help with a password reset.
Porting your number illegally can, in some instances, then lead to criminals gaining control of your accounts.
This type is scam is difficult to prevent, as it involves a legitimate service, in this case number porting. Consider using something other than your mobile phone number for two-factor identification.
IDCare says using a banking app can also save you some trouble as they have the ability to temporarily freeze your accounts and cards in the event of any nefarious activity.
