Mobile number fraud happens when a scammer takes control of your phone number or makes unauthorised changes to your mobile account. Once they have access, they can receive verification codes and reset passwords. 

This can give them access to: 

• Bank accounts  

• myGov and other government services  

• Email and social media accounts  

• Subscription and rewards programs  

Because many services rely on SMS verification, your mobile number can be used to unlock multiple accounts. 

Scammers use different methods to take control of a mobile number. Some of the most common include: 

Phishing Attempts 

Fake emails or text messages may ask you to click a link or provide personal details. These are designed to steal your information. 

Data Breaches 

If your personal data has been exposed, scammers can use it to impersonate you and request account changes. 

Email Account Takeover 

If your email is compromised, scammers can reset passwords and request access to your mobile account. 

Stolen Personal Information 

Scammers may use your ID details to convince a telco provider to transfer your number. 

It is important to act quickly if you notice anything unusual. Common warning signs include: 

• Unexpected alerts about changes to your mobile account  

• Verification codes you did not request  

• Password reset emails you did not initiate  

• Unusual login attempts  

• Your phone suddenly losing signal or showing “SOS only”  

A sudden loss of service can be a strong sign that your number has been taken over. 

If you think your mobile number has been compromised, act right away: 

1. Contact your bank immediately  

2. Reach out to your mobile provider  

3. Change passwords on all your accounts  

4. Monitor your bank and online activity  

If your personal details have been exposed, you can also contact IDCARE for support. 

There are simple steps you can take to reduce your risk: 

Stop 

Do not click unexpected links or download attachments you were not expecting. Avoid sharing personal details unless you are sure who you are dealing with. 

Check 

Verify any contact from your telco by using official channels such as their website or app. Regularly check your account for unusual activity. 

Protect 

Use strong and unique passwords. Enable multi-factor authentication where possible. Delete emails that contain sensitive information, especially those with ID documents. 

Your mobile provider also plays an important role in keeping your number secure. Many Australian telcos, including Yomojo, encourage customers to stay alert and take simple steps to protect their accounts. 

Using secure account details, keeping your contact information up to date, and reaching out to support quickly if something seems off can help reduce the risk of unauthorised access. 

If you ever notice unusual activity on your mobile service, it is important to contact your provider as soon as possible so they can help secure your account. 

As more services rely on mobile numbers for security, scammers are finding new ways to take advantage of this. Mobile number fraud is not just about losing access to your phone. It can lead to financial loss and identity theft. 

Staying informed and acting quickly can make a big difference. 

Your mobile number is more than just a way to stay connected. It is a key part of your digital identity. Taking a few simple precautions can help keep your information safe.
