Some older Samsung phones could fail to reach Triple Zero (000) during emergencies, Optus has warned. The telco will block the affected models from its network within the next month to ensure all devices can contact emergency services.

When a mobile phone cannot connect to its usual network, it automatically switches to another available network to reach Triple Zero.
