3G Only
Phones operating solely on 3G have been blocked from the network and can't make calls or use data.
If your mobile device was affected by the 3G shutdown, you may have lost partial or complete access to your mobile service. If we have contacted you, indicating that our records indicate you may have recently used an affected device then it's crucial that you carefully review the information below to ensure continued service.
The Telstra Wholesale Mobile Network has phased out their 3G services. This change enhances 4G networks, while enabling capacity, speed, and reliability expansion for 5G. The transition aimed to deliver improved connectivity and faster, low-latency communication across Australia. To stay fully connected, you'll need a 4G device with up-to-date software and settings. If it's a mobile phone it will require VoLTE (also known as HD Calling) capability that can make emergency calls over 4G.
From 28 October 2024, due to new Australian Communication and Media Authority (ACMA) regulations, mobile phones that are 3G-only, 4G non-VoLTE or make emergency calls over 3G had their network access blocked.
Non-calling devices such as Internet of Things (IOT), Machine-to-Machine (M2M) devices inc smart meters & sensors plus mobile broadband devices, tablets, laptops, smartwatches, etc that operate on 3G-only are no longer able to access the network.
4G VoLTE Mobile Phones that can make VoLTE emergency calls and non-calling 4G devices are still able to connect to the mobile network for calls and/or data according to the respective device capability.
Phones operating solely on 3G have been blocked from the network and can't make calls or use data.
4G non VoLTE phones are also blocked. 4G non-calling devices without VoLTE can continue to access data.
Any calling device that can't make calls to emergency services (000) over 4G VoLTE has been network blocked.
3G-only non-calling devices inc IoT, M2M, tablets & dongles can't connect. 4G non-calling can still access data
4G VoLTE capable devices need the correct software version and settings in order to make VoLTE calls.
Not all 4G devices support every band. Those lacking Band 28, our network's main 4G band, will be most affected.
ALDImobile has notified account holders via email and SMS where network data suggests incompatible device usage. If you've received such a notification, your device is likely affected. However, it's crucial to verify this applies to your current device. There's an SMS tool that will let you know, based on recent data, whether you need a hardware or software update.
If you're using a mobile phone that's been impacted by network updates, it's essential to replace it with a 4G VoLTE version that makes emergency calls over 4G. Or, if your phone requires updated software/network settings to enable 4G VoLTE, update your settings. If you have a 3G non-calling device you will need to replace it with a 4G version. As the shutdown is already completed it's best to take action ASAP in order to avoid further disruptions.
Outright devices, including low-cost mobile phones are available from many retailers, both online and in store. Replacement phones should be unlocked, support 4G VoLTE for all calls, including to emergency services. All 4G devices (including non-calling), should be compatible with ALDImobile's network bands and frequencies, particularly 4G Band 28.
The shutdown of Australia's remaining 3G mobile networks began 28 October 2024.

What is VoLTE?
What are the benefits?
VoLTE is the next step in voice calling technology, so there are many benefits, including:
How do I start using VoLTE?
To begin using VoLTE you will need a device which is compatible with the network and is VoLTE capable.
To check if your handset is compatible, there are a few things you can do:
Visit your handset manufacturer's website and check the network specs for your specific handset.
Ensure your handsets software is up to date and update if necessary.
Check your handset's mobile network settings. Different manufacturers put mobile network settings in different places, so visit your handset manufacturer's website for specific details on how you can enable VoLTE from handset, provided that it is compatible.
How am I charged if I use VoLTE?
Can I still call 000 on VoLTE?
Yes, calls to 000 will function as normal.

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:
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:
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.
