Critical update: Following ACMA regulations, devices that cannot make emergency calls over 4G VoLTE were blocked from the network from 28 October 2024.

Emergency calling capability
Most modern 4G VoLTE devices will continue making emergency calls after the shutdown. However, some older 4G devices are hardwired to use 3G specifically for emergency calls - this cannot be changed through settings or updates.

Impact on affected devices
If your mobile phone uses 3G for emergency calls:

• It was blocked from connecting to the network
• Cannot be modified to work after shutdown
• Must be replaced with a compatible device

This applies even if your device can make regular calls over 4G VoLTE.

Checking your device
Text '3G' to 3498 to verify your device's emergency calling capability. The tool will tell you if you need:

• A hardware upgrade (new device)
• Software updates (if applicable)

You can also validate whether a device has been blocked by visiting the Telstra Wholesale blocked device checker and entering your device IMEI. 

Important: Do not call 000 to test your device. This interferes with emergency services and won't confirm compatibility.

Required action
If your device cannot make emergency calls over 4G we strongly recommend upgrading to a newer, compatible device from a reputable seller in Australia and verify emergency calling capability before the shutdown. This will ensure you can continue making calls to 000 and other emergency services after the 3G network is decommissioned.

Remember: Emergency calling capability is built into the device hardware. If your device is incompatible, it must be replaced - no settings changes can fix this limitation.
