A major Telstra network outage has disrupted mobile phone and data services across Australia, leaving thousands of customers unable to connect.

The outage also affected users of Boost Mobile, Belong, and ALDI Mobile, as they operate on Telstra’s network.

Many customers reported their phones showing “SOS Only” while calls, texts, and internet services stopped working.

The disruption also impacted public transport, EFTPOS payments, and some emergency communications in several regions.

Telstra says it has restored most services and is continuing to investigate the cause, with no evidence of a cyberattack so far.

Authorities have urged customers to stay updated as engineers work to fully restore the network. (nine.com.au)
