Repeated Call Spam from 04 4013 5275
One contributor has reported receiving multiple calls from 04 4013 5275 (also written as 0440135275) and related numbers in the same range. What stands out about this report is that none of the callers bothered to leave a voicemail message, a classic indicator of automated spam dialling campaigns or nuisance calling patterns.
The number is allocated to Optus Mobile, so the calls appear to originate from an active mobile service rather than a dedicated business line. The pattern of repeated calls across a number range suggests coordinated calling activity typical of spam operations.
Call Pattern from 0440135275
The contributor noted that various numbers within the same range as 04 4013 5275 have called repeatedly. The absence of voicemail messages is significant - legitimate callers almost always leave a message when unable to reach someone, especially on first contact. The fact that multiple numbers from the same range are involved indicates this may be part of a larger spam operation cycling through similar numbers.
This pattern of repeated calls from 04 4013 5275 and related numbers with no message left is consistent with automated calling systems or spam networks designed to generate call volume rather than establish genuine communication.

WRITE A REVIEWFrequently Asked Questions
Why do callers from 04 4013 5275 not leave voicemail messages?
The contributor's report suggests the calls from 04 4013 5275 are part of an automated spam campaign. Legitimate callers nearly always leave a message on first contact, especially when trying to reach someone for genuine business purposes. The pattern of repeated calls with no voicemail is typical of robocalling or spam dialling systems designed to generate call volume rather than establish real communication.
Should I be concerned about repeated calls from 0440135275 and similar numbers?
Yes, the pattern reported for 0440135275 warrants concern. Multiple calls from a range of similar numbers with no voicemail left indicates coordinated spam activity. This is not typical behaviour from legitimate callers and suggests either a spam operation or a nuisance calling network cycling through numbers.
How can I stop calls from 04 4013 5275 and the number range?
Block 04 4013 5275 immediately on your phone, then add other numbers from the same range that have called you to your blocklist as well. Contact Optus (your provider if you're an Optus customer) to report the spam campaign. Register with the Do Not Call Register at donotcall.gov.au to reduce marketing calls generally, and report the pattern to ACMA at acma.gov.au.
What does it mean if multiple numbers call me from the same range as 0440135275?
Multiple calls from different numbers within the same range, as reported for 0440135275, indicates a coordinated operation rather than an error or one-off misdial. Spam operations often cycle through similar number ranges to avoid individual number blocking. If you're receiving calls from 04 4013 5275 and similar numbers in that range, you're likely targeted by the same spam network.
Is 04 4013 5275 a legitimate Optus number?
The number 0440135275 is allocated to Optus Mobile, so it is a valid Optus mobile service number. However, legitimate Optus services would leave voicemail messages and not repeatedly call without attempting to communicate. The pattern reported for 04 4013 5275 suggests the number is either compromised, spoofed, or being used for spam purposes despite its Optus allocation.
What should I do if I accidentally answer a call from 04 4013 5275?
If you answer 0440135275, do not engage with the caller. Hang up immediately without providing any personal information, confirming your identity, or asking questions. Do not press any buttons if prompted, as this confirms your number is active and may lead to more calls. Simply disconnect and block the number right away.
