Nearly half a million Australians might be carrying phones that can’t dial for help when it matters most. Optus has warned regulators that up to 470,000 Samsung phones connected to its network could fail to call Triple Zero (000) — a scenario the company itself calls a “worst-case situation.” The revelation adds another chapter to Australia’s growing concerns about the reliability of emergency communications. But here’s where it gets even more alarming: this issue ties back to the nationwide shutdown of the 3G network.
During a Senate estimates hearing, Optus disclosed that it had identified hundreds of thousands of potentially affected Samsung devices. The investigation began after reports surfaced that numerous older Samsung models couldn’t reach Triple Zero through Vodafone’s network following the flawed 3G phase-out. The issue became heartbreakingly real when TPG Telecom, Vodafone’s parent company, confirmed that one customer recently died after his outdated phone software stopped an emergency call from connecting—even though Vodafone’s mobile network was fully operational at the time.
According to the Australian Communications and Media Authority (ACMA), TPG has already blocked more than 7,100 malfunctioning Samsung devices. Meanwhile, Telstra has located around 114,000 customers with phones that need urgent software updates. Of those, over 4,100 cannot be fixed at all and will be disconnected from Australian networks between now and January. Telstra’s own tests revealed that these phones only fail to complete Triple Zero calls when the Telstra or Optus networks are unavailable, forcing them to switch to Vodafone—a process the older devices can’t manage correctly.
ACMA spokesperson Cathy Rainsford confirmed that Optus is now “manually” testing roughly 470,000 Samsung phones to determine how many truly need intervention. Fortunately, she added, most can probably be repaired with a simple software update. “As of November 14, Optus said the maximum possible number of impacted devices was about 470,000,” Rainsford told senators. “The vast majority are expected to be fixable, and Optus is carefully verifying that.”
Samsung has released its own statement, advising that phones older than seven years will likely require replacement altogether. However, most of the affected models should return to normal function once updated. Customers with impacted devices will have 28 days after carrier notification to update or replace their phones—after which uncorrected devices will be barred from connecting to any Australian mobile network.
This isn’t just a technical glitch; it’s a matter of public safety. Under new telecommunications rules introduced in 2024, providers must alert customers if their phones can’t connect to Triple Zero and then block noncompliant devices to prevent confusion during emergencies. Carriers are also required to ensure that emergency calls can connect through other networks even during major outages—a safeguard that clearly faltered in this case.
When questioned by Liberal Senator Sarah Henderson, ACMA admitted it is currently investigating two possible rule breaches and has demanded detailed information from Samsung and TPG. Senator Henderson condemned what she described as a serious public safety oversight and criticized the federal government for not launching a nationwide awareness initiative sooner. "This is not just a technical failure—it’s a human safety issue," she warned.
This controversy comes on the heels of a turbulent period for Australia’s telecommunications sector. Following the nationwide Optus outage in September—which has been linked to at least two deaths—trust in the emergency call infrastructure has taken a major hit. The 3G shutdown, rolled out from January to November 2024 to make room for faster 4G and 5G networks, was supposed to be a leap forward. Instead, it has exposed a hidden vulnerability affecting both 3G-only devices and certain older 4G models that automatically switched to 3G for emergency calls.
Only late in October—months after the 3G network was decommissioned—did telcos realize that many Samsung phones were failing to route Triple Zero calls properly through Vodafone. And that shocking delay raises the biggest question of all: How could such a critical flaw go unnoticed until lives were already lost?
So what do you think—is this a simple technical oversight, or has Australia’s rush toward next-generation technology put lives at risk? Should telcos face heavier penalties, or does the responsibility fall on consumers to keep their phones updated? Leave your thoughts below—this debate is far from over.
