What to do if your mobile number has been stolen


Someone might have stolen your mobile number if:

  • You cannot make or receive calls or messages when you usually can;
  • Your mobile is showing ‘SOS only’ where reception bars usually appear.


What to do if you notice these signs


  1. Check if your mobile service has Ported Out status by logging in to My Account.
  2. Check your email for any notifications from TPG regarding a mobile service transfer.
  3. Contact us as soon as possible if you suspect someone stole your number.


We also recommend that you:

  • Contact your bank or financial institution straight away and tell them someone might be committing fraud;
  • Consider changing your passwords for accounts such as for your bank, email and social media;
  • Report any fraud to local police or the Australian Federal Police;
  • Report any cybercrime relating to identity theft and online fraud to the Australian Cyber Security Centre;
  • Contact IDCARE on 1300 432 273 if you want help with identity crime or cyber security;
  • Report the activity to Scamwatch.


How someone can steal your number


If a criminal has your personal information, they can steal your mobile number in a couple of ways:

  • An unauthorised port - the criminal contacts a new telco and pretends to be you, sets up an account and ports your number.
  • A SIM swap - the criminal contacts your current telco pretending to be you and requests a new SIM card that has your number.

Once a criminal has your number, they can receive SMS verification codes. This means they can get access to services such as your bank, email and social media.


How we can help


If someone ported your number without your consent, we can reverse the port.


If someone made a SIM swap without your consent, we can deactivate the SIM card and send you a new card.


Before a mobile number is ported, TPG carries out additional validation checks to ensure the port is authorised. We send a unique verification code via SMS to the affected mobile number. This verification code is required to authorise a porting request, which helps to protect our customers from having their mobile numbers stolen.
