Apple has paused the rollout of several recent iOS updates after Australian users reported network connectivity problems, an issue that appears to affect older iPhone models on local carrier networks.
The disruption follows Apple’s release of multiple software updates this week, including iOS 26.2.1 and several maintenance versions for older devices, which collectively triggered unexpected compatibility issues in Australia.
According to a newly published support notice, Australian carrier Telstra is investigating a fault that prevents some older Apple devices from connecting reliably to its network after installing specific iOS updates.
Telstra confirmed that the issue affects voice services and data connectivity, with particular concern around failed calls to Australia’s 000 emergency number, elevating the problem beyond routine software inconvenience.
The carrier advised customers using impacted devices to delay installing recent software updates until engineers confirm the underlying compatibility problem has been resolved in coordination with Apple.
Affected devices and paused updates
Telstra identified the iPhone 8, iPhone 8 Plus, and iPhone X as affected when updated to iOS 16.7.13, indicating a link between the software version and network registration behaviour.
In response, Apple halted the global distribution of several updates intended for older hardware, including iOS 18.7.4, iOS 16.7.13, iOS 15.8.6, and iOS 12.5.8.
Update tracking also shows Apple has resumed signing iOS 12.5.8, iOS 15.8.6, and iOS 18.7.4, while iOS 16.7.13 remains unavailable, limiting downgrade and restore options for affected users.
Apple’s decision to pause availability reflects a cautious approach when network reliability becomes compromised, particularly in regions where emergency calling standards impose strict operational requirements.
Importantly, Apple’s support documentation confirms the paused updates contain no security patches, which limits the immediate risk for users who delay installation while the issue remains unresolved.
That distinction matters because it allows users to prioritise connectivity and emergency access without exposing devices to known security vulnerabilities during the temporary pause.
What still works and what to expect
Apple has confirmed that iOS 26.2.1 remains unaffected and continues to roll out normally to supported iPhones, suggesting the issue is isolated to legacy update branches rather than the latest platform release.
The situation highlights ongoing challenges in maintaining compatibility between ageing hardware, evolving carrier infrastructure, and regional network standards, especially as operating systems receive extended long-term support.
Apple and Telstra have not provided a specific timeline for a fix, but both companies indicated active collaboration to restore full network functionality for impacted devices.
Users with older iPhones in Australia are advised to monitor carrier and Apple support channels for further updates before installing paused software versions.
