Critical update: Following ACMA's Emergency Call Service Determination, devices that cannot make emergency calls over 4G VoLTE were blocked from accessing the network from 28 October 2024.

Affected devices

Mobile phones
Devices are blocked from the network if they:

• Are 3G-only
• Don't support VoLTE calling
• Make emergency calls over 3G

Devices with limited 4G band support may experience partial or full coverage gaps, depending on your location and the specific bands supported.

Other connected devices
Any device with a SIM card must be 4G compatible to continue working. This includes tablets, laptops, security cameras, monitoring devices, medical alarms, and IoT devices.

Network requirements
Calling devices must support VoLTE for all calls, including emergency calls. For optimal coverage, devices should be compatible with Telstra Wholesale network 4G bands: 700MHz (B28, most important), 1800MHz (B3), 2100MHz (B1), and 2600MHz (B7).

Checking your device

Quick check
Text '3G' to 3498 from your device. You'll receive current device information, network capability status, and any required upgrade information.

Detailed verification
Search your device specifications online to check VoLTE and 4G band support. Verify the software version requirements and ensure emergency calling capability over 4G is supported.

Software considerations
Even compatible devices may need software updates or configuration changes. This includes network settings updates, VoLTE activation, and emergency calling setup. Check your device settings and install any available updates.

Important: The 3G shutdown has already completed. Check your device now to avoid service interruption.
