Amaysim pays $138,600 over anti-fraud breaches

Amaysim has paid a $138,600 penalty after failing to carry out mandatory identity checks before transferring mobile numbers from other providers, resulting in unauthorised transfers.

An Australian Communications and Media Authority (ACMA) investigation found Amaysim Mobile Pty Ltd breached anti-fraud rules on 13 occasions in 2025.

The regulator has also issued a formal warning to Ezee Mobile following a separate investigation into its consumer information obligations.

Identity checks failed

ACMA chair Nerida O’Loughlin said robust identity verification processes were essential to protect consumers from mobile number fraud.

“These checks are critical to prevent fraudsters hijacking mobile services and exposing Australians to identity theft, financial harm and other serious consequences,” O’Loughlin said.

“While the ACMA is not aware of any financial losses arising from these breaches, victims can face significant distress, disruption to essential services and the time-consuming process of restoring access to compromised accounts and identities.”

The ACMA has accepted a court-enforceable undertaking from Amaysim requiring an independent review of its policies and procedures, implementation of recommended improvements and regular reporting to the regulator.

Ezee Mobile receives formal warning

In a separate investigation, the ACMA found Switch Mobile Networks Pty Ltd, trading as Ezee Mobile, failed to provide consumers with information about reporting suspected scams to police and government support services.

The regulator issued the company a formal warning.

The Telecommunications (Mobile Number Pre-Porting Additional Identity Verification) Industry Standard 2020 requires telcos to carry out additional identity verification before transferring a mobile number to their service.

Providers must also publish information explaining where consumers can report suspected fraudulent number transfers.

Penalties exceed $5.2 million

The actions form part of the ACMA’s ongoing crackdown on mobile number fraud. Telcos have paid more than $5.2 million for breaches of the rules to date.

The regulator advises consumers who suspect they have been targeted by a phone scam or fraud to contact their telco and financial institution immediately.
