Most people protect their home with a lock on the door. But your mobile number? That's a key too – and scammers know it. If they get hold of it, they can access your bank, email, government accounts and personal information.
This page will help you to:
Protecting you and your mobile service from unauthorised access is really important to ALDI Mobile. That’s why we use extra security checks – including multi‑factor authentication (MFA) for certain high‑risk transactions – before we make some changes to your account.
You also play an important role in keeping your service secure. Even with strong checks in place, scammers may be able to pass security checks if they can access your mobile phone, My ALDI Mobile or your email account. These simple tips can make it much harder for scammers to impersonate you.
If a scammer can get into your email, knows your My ALDI Mobile password or takes control of your phone, they may be able to pass the same security checks we use to protect you.
Why it matters: If someone can access your phone, they can receive security codes sent by text.
If you are receiving unwanted marketing calls, ask the caller to stop calling you and remove you from their database. You can also consider adding your number to the Do Not Call Register to reduce most telemarketing calls.
Some changes to your mobile service are more sensitive than others. If a scammer managed to make them, they could gain control of your service or account.
That's why we use extra identity and MFA checks for these requests.
After you’ve logged into My ALDI Mobile or when you contact us, there are some things you may ask us to do that we treat as high‑risk transactions.
A high‑risk transaction is any request that:
These are high‑risk because your mobile number and account details can be used to help access other online accounts you have, like banking, email or social media.
Why it's high-risk
If a scammer can stop you using your number or move it to another SIM, they may be able to pass security checks for your other online accounts (like banking or social media) using your number instead of you.
Examples
Why it's high-risk
Anything that affects how you log in, how you are identified and who can access your account. If a scammer changes these, it could lead to you losing control of your service.
Examples
If something doesn’t feel right, take a moment before you act.
Contact the organisation using a number you find yourself.
Never share codes, access or passwords with anyone.
For high-risk transactions, ALDI Mobile uses multi-factor authentication (MFA) to check more than one thing and confirm it's really you, not someone pretending to be you.
If you ask us to swap your number onto a new SIM card (for example, for a lost or damaged phone), we treat this as a high‑risk transaction and use extra identification and MFA checks before we proceed. This may mean we cannot complete the request if we cannot verify that it is really you.
Porting is when your mobile number is moved from one provider to another. If scammers can get your number moved to a service they control, they may be able to receive your calls and text messages – including security codes used to access your bank, email and other important accounts.
Act quickly. If you notice any of the signs below, or you know someone has accessed your email, banking or other important accounts, treat it as urgent.
We can help you check your service and secure your ALDI Mobile account if you’re affected.
Protect your money, secure your accounts, and report the scam:
Do not click any links or open attachments and do not reply with personal or payment information. Access My ALDI Mobile only via the official website or app, or contact us using a number from our website. You can also report scam messages that appear to be from ALDI Mobile to Scamwatch and, for SMS or calls, follow the blocking steps on your device.
Whether you contact us by phone, online form or email, we ask identification questions to confirm you are authorised to access the account before we discuss or change anything. This helps stop someone using basic information about you (like your name and number) to take over your service.
Yes. You can set up a phone PIN known only to you so we can quickly identify you when you call, and you can ask us to add a security question to your account. Choose information that is not easy for others to guess or find online
The SMS Scam Filter looks for suspicious patterns in messages travelling across the network and blocks messages that match known scam campaigns before they reach your phone. Messages are only blocked when they meet agreed criteria and have been confirmed as part of a scam campaign by security experts.
Most ALDI Mobile services have access to the SMS Scam Filter automatically. If you want to opt out, send an SMS to 0438 214 682 with the words FILTER OFF. To turn it back on, send FILTER ON to the same number. To check if the filter is on or off, send an SMS to 0438 214 682 with the words FILTER STATUS.
Use a passcode, fingerprint or face unlock on your phone and set it to auto‑lock; do not store PINs or passwords on your device; and keep your software and apps up to date. Also review your social media profiles and remove your mobile number and birthdate from public view so scammers cannot easily collect this information.
Scammers use many stories, but most scam messages fit into a few common types:
Bank or company impersonation – messages that look like they’re from your bank, ALDI Mobile, a delivery company or government agency saying there’s a problem with your account and you must click a link or call a number urgently.
Delivery, toll or bill problems – texts or emails about an unpaid toll, missed delivery or overdue bill asking you to click a link to fix it or pay a small fee.
Refunds, prizes or special offers – messages saying you’re owed a refund, have won a prize or can get a gift card or investment deal that seems too good to be true.
“Hi Mum / Hi Dad” or family emergencies – messages pretending to be from a child or family member with a “new number” or in an emergency, asking you to transfer money.
Password, code or personal‑info requests – messages asking you to reply with passwords, one‑time codes, bank details or to log in through a link in the message.
If a message does any of these, treat it with caution and contact the organisation using a phone number or website you find yourself – not the details in the message.
Stop and think before you tap. There is a good chance it’s a scam if the message:
Is unexpected and tries to make you act immediately
Asks you to click a link, call a number in the message, or download an attachment
Says your account has been hacked, locked or will be closed if you don’t act now
Asks you to move money, buy gift cards, or share personal or banking details
Comes from a strange email address or number, or doesn’t use your name
You can choose answers that are memorable to you but not true in real life – for example, a made‑up best friend’s name. This makes it harder for someone who knows you, or who can see your social media, to guess your answers.
Hang up immediately. Genuine staff from ALDI Mobile, your bank or government agencies will not force you to download software or take control of your computer to fix a problem or process a refund. If you have already installed something or given access, disconnect from the internet, run an anti‑virus scan and contact your bank and a trusted computer technician.
Be careful, especially if the number looks like a premium or overseas number. Some scams rely on you calling back a number that hangs up quickly, then charging high call‑back fees. If you do not recognise the number, it is usually safer not to call back.
Most phones let you block numbers in your recent calls or messages list so future calls and texts from that number are blocked. Some devices also let you silence unknown callers or use apps that help identify and block scam calls and texts. You can also list your number on the national Do Not Call Register to reduce marketing calls.
They are high‑risk because they may cause you to lose access to your service or change key personal, contact or security information on your account. If a scammer could make those changes, they might then use your number or new details to access your banking, email or social media accounts.
The same technology is used for many different transactions. Some requests that seem small to you may still affect how you access your account or how we identify you, so we treat them as high‑risk and ask you to confirm with a one‑time code.
If you do not receive your code, first check that your phone has coverage and that your contact details are up to date. If you still cannot receive the code, or you no longer have access to your primary contact number, contact us. We may still be able to help, but we may need extra security checks and it can take longer.
For many SIM swaps and port‑in requests, we must confirm an SMS code sent to your number before we go ahead and there are no workarounds. If you cannot confirm the code, we may not be able to complete that request, although we may be able to help with other account issues after further checks.
If your number has been fraudulently ported away from ALDI Mobile, we may ask you to complete a port reversal authority so that we can attempt to move the number back into your name. This form gives us permission to request the reversal from the other provider.
Scam calls and texts are designed to steal money or personal information; marketing calls and texts promote legitimate products or services but may still be unwanted. Scam messages should be ignored, blocked and reported, while marketing communications can usually be stopped by asking the caller not to contact you again or replying STOP to SMS.
Here are some MFA how-to guides for popular email providers:
If your email provider isn't listed above, reach out to them directly to see how to enable MFA.
A key way to protect your ALDI Mobile account is to secure your email account with Multi-Factor Authentication (MFA).
Multi-Factor Authentication adds an extra layer of security to your email login process. Instead of just entering a password, MFA requires a second form of verification, like a code sent to your phone, a fingerprint scan, or an authentication app.
This means even if someone steals the password to your email account, they still can’t access it without that second factor.
Here's five reasons to enable MFA on your personal email address:
Your ALDI Mobile account, your bank account and many other online services, use your email address for password resets.
If someone gains access to your email inbox, they can potentially reset the password to any online account that your email address is linked to.
Having strong password isn't enough anymore. Passwords can be compromised through phishing scams, data breaches and other types of cyber attacks.
MFA significantly reduces the risk of unauthorised access to your email inbox.
Cybercrime is on the rise and the cybercriminals are getting smarter.
MFA helps protect you even if you accidently click on a malicious link or enter your details into a fake website.
Knowing that your email address is protected with MFA gives you confidence that your personal information is safer, even if your password is leaked.
Most major email providers offer simple, easy MFA setup options. It usually takes just a few minutes and the security benefits are long-lasting.
A common sign is that your phone suddenly shows “SOS only” and you cannot make or receive calls, send SMS or use data, even though your handset and SIM are not damaged. This can also happen during outages or faults, so contact us to check whether your number has been ported.
Tell us when the problem started, what messages or calls you have received, and whether your bank has noticed unusual activity. We may ask you to complete a port reversal authority or update your phone PIN as we work to secure your service.
In addition to contacting your bank and ALDI Mobile, consider contacting IDCARE or similar identity support services for help with securing your identity. You should also report the scam to the National Anti‑Scam Centre via Scamwatch and, if money has been stolen or your identity misused, to the police assistance line.
When someone gets access to your ALDI Mobile account, there are many ways you could be impacted:
Any mobile service on the account could be swapped to a different SIM card
This means that the number will be disconnected from the current SIM card and it will be moved to a new SIM card.
Whoever has the new SIM card will now start receiving phone calls and messages sent to that number.
The contact, personal and security information on that account could be changed
If someone gains access to your My ALDI Mobile account, they could also change key information on the account that may make it harder or impossible for you to gain access again.
This includes changes to the name on the account, the date of birth, the contact email or mobile number and the names of any authorised contacts on the account.
Your usage information could be exposed
Someone with access to your My ALDI Mobile account will also be able to see the usage of each mobile service on the account. That means they could see the mobile numbers you've been interacting with and the times and dates you interacted with them.
