Persistent Calling Pattern from 0421 242 910
A single contributor has reported concerning calling behaviour from 0421 242 910 (also written as 0421242910), an Optus mobile number. The caller made multiple attempts in rapid succession without leaving a message, creating a pattern that suggests either intentional persistence or an automated system.
When the contributor attempted to call back 0421242910, they received a message indicating the number was not available. This discrepancy - where the number can call out but apparently cannot receive calls - is unusual and may indicate a spoofed or masked number rather than a genuine Optus mobile.
What Happened with 0421 242 910
The contributor received two consecutive calls from 0421 242 910 without any voicemail left. After the calls disconnected, the caller tried again. Each time the contributor attempted to return the call to 0421242910, they encountered a "not available" message, preventing any callback connection.
This pattern of repeated calling attempts combined with inability to be called back is a common indicator of spoofed or masked calling technology, often used by spam operators, scammers, or automated dialling systems.

WRITE A REVIEWFrequently Asked Questions
Why did my callback to 0421 242 910 fail when the number called me?
Spoofed or masked numbers often call outbound but cannot receive incoming calls. When 0421 242 910 calls, it may be masking the true originating number, allowing outbound calls but blocking callbacks. This is a red flag for spam or scam activity. Do not attempt multiple callbacks to 0421242910, as this may incur charges or connect you to unintended destinations.
Is 0421 242 910 a real Optus number?
While 0421 242 910 is registered as an Optus mobile number, the calling pattern reported (multiple attempts, no voicemail, failed callbacks) suggests the number may be spoofed or masked rather than being used legitimately. Legitimate callers can receive callbacks and will leave voicemail messages.
What should I do if 0421242910 keeps calling me?
Block 0421 242 910 immediately on your phone. If calls from 0421242910 persist after blocking, contact Optus customer service to report the harassing pattern. You can also lodge a complaint with ACMA at acma.gov.au and share your experience on Reverseau to alert other contributors.
Could 0421 242 910 be a legitimate business?
Unlikely. Legitimate businesses and services always identify themselves and leave voicemail messages. The pattern from 0421 242 910 - multiple rapid calls without identifying information and inability to be called back - is characteristic of spam or automated dialling systems, not genuine business contact.
Should I call back 0421242910 to find out who it is?
No. The fact that callbacks to 0421 242 910 fail suggests a spoofed number. Attempting to call back 0421242910 may route you to an incorrect number, incur unexpected charges, or connect you to a scammer impersonating a legitimate service. Let voicemail handle identification instead.
How do I report 0421 242 910 to Optus?
Contact Optus customer service through the Optus website or call them on their official number. Explain that you've received repeated calls from 0421 242 910 that appear to be spoofed or masked. Request that Optus investigate the number and block further calls. You can also report the pattern to ACMA and contribute your report to Reverseau.
