Some older Samsung phones no longer meet national emergency-call requirements and will be blocked from the Optus network.

If you’re affected, you’ll receive an SMS and email from 22 October 2025. Check your device and either replace it with a compatible 4G or 5G handset OR make sure the software is updated to Android version 13 or higher to stay connected.
