Community report for 0401 559 384 (0401559384): Robocall claiming unusual phone plan activity. Contributor on prepaid plan identified as fraud.
Robocall Scam Report for 0401 559 384
One contributor has reported a robocall from 0401 559 384 (also written as 0401559384) delivering a pre-recorded message in both Chinese and English. The message claimed to alert about unusual activity on the recipient's phone plan, but the contributor immediately recognised this as fraudulent since they operate on a prepaid plan where such account activity warnings would be irrelevant.
This type of robocall targeting mobile customers represents a common scam vector. The use of multiple languages suggests the caller is attempting to reach a broad audience, increasing the likelihood of reaching someone who may panic at the mention of account irregularities.
What the Robocall from 0401 559 384 Claims
The automated message received from 0401559384 focused on creating urgency by referencing "unusual activity" on a phone plan. This phrasing is designed to prompt recipients into immediate action, typically attempting to get them to either press a key to speak with support, call back a provided number, or provide account information to "verify" their identity.
The contributor's knowledge that they were on a prepaid plan provided protection against this scam. However, customers on standard postpaid plans might be more vulnerable to this exact message, as account activity alerts are a normal part of their service.
Report Details and Timing
The robocall to 0401 559 384 arrived as a voicemail message on 7 April 2026. The use of voicemail delivery rather than live connection is typical of large-scale robocall campaigns, allowing scammers to reach many numbers without requiring operator involvement. The Optus mobile network allocation suggests this campaign may be targeting Optus customers specifically, though the number itself could be spoofed.
What to Do If You Receive a Call from 0401 559 384
If 0401559384 or a similar number contacts you with claims about phone plan activity:
- Do not: Press any keys, call back the provided number, or share personal information like name, account number, or card details
- Do: Hang up immediately and delete the voicemail
- Do: Contact your actual provider directly using the number on your invoice or their official website if you need to verify account status

WRITE A REVIEWFrequently Asked Questions
Why would a robocall claim unusual activity if I'm on prepaid?
Robocalls from 0401559384 and similar scam numbers typically use generic messages designed to work against a broad audience. The 'unusual activity' alert is a common social engineering tactic because it creates urgency and fear, prompting some recipients to act without thinking. Prepaid customers aren't vulnerable to this specific claim, but the scammer's message isn't targeting anyone in particular - it's a numbers game.
Is 0401 559 384 actually an Optus number?
The number 0401559384 is allocated to Optus mobile, but this doesn't mean Optus sent the call. Scammers routinely 'spoof' phone numbers to make their calls appear to come from legitimate providers or local numbers. The fact that 0401 559 384 showed up on caller ID doesn't confirm the call actually originated from that number.
What happens if I press a key on the robocall from 0401 559 384?
If you press a key during the robocall from 0401559384, you typically either confirm your number is active (adding it to scam call lists) or connect to a scammer posing as customer support. Either outcome is bad - you'll either receive more scam calls, or be pressured to provide personal information or payment details.
How do I block 0401 559 384 on my phone?
On most Australian mobile phones, you can block 0401559384 by opening the call history or voicemail, finding the number 0401 559 384, and selecting 'Block' or 'Block Number'. The process varies slightly by phone type (iPhone vs Android), but all modern phones support call blocking. Contact your provider's support if you need help.
Should I call back the number in the robocall message from 0401 559 384?
Never call back any number mentioned in a robocall or suspicious message from 0401559384 or similar scam numbers. The 'callback request' is part of the scam. Instead, if you're concerned about your account, use the phone number on your official service invoice or the provider's website to contact them directly.
Can Optus help me stop robocalls from 0401 559 384?
Contact Optus directly to report the spoofed robocall from 0401559384. While they can't stop scammers from using number spoofing, reporting helps them track patterns and assist other customers. You can also enable call filtering features offered by Optus to block suspected scam calls, and report the number to Scamwatch and ACMA for broader action.
