Action may be required to avoid interruption

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.

Why did this happen?

Why did this happen?

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.

What devices are affected?

What devices are affected?

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.

3G Only

3G Only

Phones operating solely on 3G have been blocked from the network and can't make calls or use data.

4G non-VoLTE

4G non-VoLTE

4G non VoLTE phones are also blocked. 4G non-calling devices without VoLTE can continue to access data.

Emergency calls over 3G

Emergency calls over 3G

Any calling device that can't make calls to emergency services (000) over 4G VoLTE has been network blocked.

Non-calling data devices

Non-calling data devices

3G-only non-calling devices inc IoT, M2M, tablets & dongles can't connect. 4G non-calling can still access data

Outdated settings

Outdated settings

4G VoLTE capable devices need the correct software version and settings in order to make VoLTE calls.

4G limited band coverage

4G limited band coverage

Not all 4G devices support every band. Those lacking Band 28, our network's main 4G band, will be most affected.

How do I know if my device is affected?

How do I know if my device is 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 my device is affected, what do I need to do?

If my device is affected, what do I need to do?

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.

We recommend updating affected devices immediately

Where can I get a compatible device?

Where can I get a compatible device?

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.

General 3G shutdown FAQs

When did 3G shutdown?

The shutdown of Australia's remaining 3G mobile networks began 28 October 2024.

This step was taken to reallocate resources to the more advanced 4G and 5G networks, which provide faster and more efficient services. The shutdown of 3G is part of an industry-wide transition by all network providers across Australia and globally towards newer, more efficient technologies.

My device stopped working when 3G shut down. What now?

If you have received a notification from us including the reference that "recent activity indicates use of a device that will be impacted", it is likely that you need to upgrade to a compatible device to continue using our services.

Please note that email notifications were sent to the account-holder, and the affected device could be any, some, or all of the devices connected to an account.

If you have multiple services it is important to check the specifications on each device to ensure that they support 4G for data and VoLTE for calls, and are compatible with the 4G and/or 5G bands that ALDImobile operates upon.

Device impacts from 28 October 2024
The Australian Communications and Media Authority confirmed specific requirements for mobile devices after the 3G shutdown. As a result, devices have been blocked from the network if they are:

  • 3G-only
  • Are a 4G phone without VoLTE capability
  • Use 3G for emergency calls even if they have 4G

Different devices, different impacts:

Mobile phones:

  • Must support 4G VoLTE for all calls, including emergency services
  • Require correct software version and settings
  • Have been blocked if they don't meet these requirements

Non-calling devices (IoT, M2M, tablets, etc):

  • 3G-only devices lose network access
  • 4G devices without VoLTE can continue accessing data
  • Must be compatible with current network bands
  • No emergency calling requirements if not phone capable

Checking your device compatibility
If you've received a notification about device compatibility:

  1. Text '3G' to 3498 for an immediate device check
  2. To validate whether a device has been blocked visit the Telstra Wholesale blocked device checker and enter your device IMEI 
  3. Verify for each device on your account
  4. Check specifications for:
    • 4G VoLTE capability
    • Emergency calling over 4G
    • Network band compatibility (especially Band 28)
    • Software/settings requirements

Multiple service considerations:

  • Check each device individually
  • Don't assume all devices on your account are affected
  • Verify specifications even if you haven't received a notification
  • Consider both calling and non-calling devices

Required actions:

  1. For incompatible phones:
    • Replace with a 4G VoLTE capable device, or
    • Update software/settings if device supports VoLTE
  2. For 3G non-calling devices:
    • Upgrade to 4G compatible versions
    • Ensure network band compatibility

Timing:

The shutdown date was aligned with regulatory requirements and network planning. To maintain uninterrupted service, ensure all your devices meet new network requirements.

Do I need a new SIM card if I upgrade my device for the 3G closure?

Existing ALDImobile SIM cards are compatible with 4G and 5G mobile devices.

However, it is important to check the size of the SIM card required for your new device. Our SIM cards are “3 in 1” which means they have a standard SIM, a micro SIM and a nano SIM all in the one card. You simply add or remove the insert frame to match the size that fits your device. 

If your new device requires a different SIM card size than your current one, you may need to add or remove inserts. Newer devices typically require smaller SIMs so it is most likely that you will need to remove rather than add an insert to fit a newer device.

What is the voice announcement I'm hearing about the 3G shutdown?

You may hear a Recorded Voice Announcement (RVA) when making outgoing calls, along the lines of:

RVA message until 28 October 2024:
"When the 3G network closes it's likely this phone won't be able to make calls, including emergency calls. Contact your service provider for details."

Updated RVA message from 28 October 2024:
"Your device may have reduced network connectivity and will not always be able to call triple zero. For your safety, upgrade to a compatible device now. Contact your service provider."

Why am I hearing this?

  • Your device has been identified as potentially impacted by the 3G shutdown or 700MHz 4G compatibility
  • The announcement serves as a reminder to upgrade your device
  • It will continue until network data shows a compatible device in use
  • Important: You cannot opt out of these announcements while using an affected device

Impact after network changes
Affected devices may lose the ability to:

  • Make regular calls, send/receive texts or access mobile data
  • Make emergency calls to 000
  • Maintain reliable network connectivity (for 700MHz incompatible devices)

Testing your device
DO NOT:

  • Call 000 to test compatibility
  • Assume your device will continue working completely

DO:

  • Use the SMS Device Checker tool
  • Text '3G' to 3498 for guidance
  • Check if you need software updates or hardware upgrade

After updating your device
Network data updates:

  • May take up to 24 hours to reflect changes
  • RVA messages will continue during this period
  • Use SMS tool to confirm update status

Checking network data updates:

  • Text '3G' to 3498
  • Review the returned device information
  • If showing new device: Data is current
  • If showing old device: Wait for update
  • Check regularly until new device appears

Still receiving RVA after device change?
If you have a new device but still hear the RVA and the SMS tool shows your new device, it may be incompatible with either 3G shutdown requirements or the 700MHz 4G network. Follow the SMS tool's advice for ensuring ongoing compatibility.

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

    How do I check if a device is 3G, 4G non-VoLTE, 4G VoLTE or 5G?

    To prepare for the 3G network shutdown, your device will need to support 4G or 5G, and VoLTE (Voice over LTE/HD calling/4G voice) for uninterrupted data and voice services.

    Note that some 4G devices lack VoLTE, limiting voice calls over 4G networks and are known as 4G non-VoLTE. Also, most 5G phones support 4G VoLTE, due to backward compatibility.

    To determine whether your current device is 3G, 4G non-VoLTE, 4G VoLTE or 5G you can check;

    1. Manufacturer information:
      • Contact your mobile device manufacturer for information about the network capabilities of your device.
    2. Device specifications:
      • Search for your phone model online to find its specifications on the manufacturer's website or on trusted tech review sites.
      • Look for terms like "3G", "4G LTE", "VoLTE" or "5G" in the network specifications.
      • If you see "5G", "VoLTE" or a similar indication, your phone is likely using Voice over LTE.
    3. Device settings:
      • For Android: Go to 'Settings' > 'About phone' > 'Network' or 'Status'.
      • For iOS: Go to 'Settings' > 'General' > 'About'.
    4. Network indicators:
      • Check the network indicator on your phone’s status bar for icons like "3G", "4G" or "LTE".
      • If you see "5G", "VoLTE" or a similar indication, your phone is likely using Voice over LTE.
    5. Test VoLTE features:
      • Make a call and see if you can use data services with 4G or 5G during the call to determine if your phone supports VoLTE.
      • If you can use 4G or 5G data while on a call, your device is likely to be using VoLTE, as non-VoLTE phones switch to 3G and cannot sustain high-speed data while on a call.

    Remember, you'll need a 4G VoLTE or 5G device to continue using both voice and data once 3G network services are switched off.

    How do I identify my device?

    To find out what device you have, follow these steps:

    1. Check the device itself: Look for the model name printed on the back or front, or displayed during start-up.
    2. Device settings:
      • For Android: Go to 'Settings' > 'About Phone' or 'About Device' for device name, model number, and manufacturer.
      • For iOS: Go to 'Settings' > 'General' > 'About' for model name and number.
    3. Use the IMEI number: Dial *#06# for the IMEI and use an online IMEI checker to lookup your device details.
    4. Original packaging: Check the phone’s original packaging for model and manufacturer information.
    5. Device documentation: Refer to the user manual or documentation for model details.
    6. Check with the retailer: Contact the retailer (or check their receipts or order confirmations) for device information, based on purchase history.

    These methods can help in identifying your mobile device. If uncertain, search online with any known features or specifications to see if you can find a match.

    What is my device's IMEI?

    An IMEI (International Mobile Equipment Identity) is a unique 15-digit number that identifies individual mobile devices. It acts like a serial number for your phone and is used to verify and distinguish devices.

    How to find your IMEI number:

    1. Dial a Code: Dial *#06# on your phone.
      The IMEI number should automatically appear on the screen.
    2. Device settings:
      • For Android: Go to 'Settings' > 'About Phone' > 'Status' > 'IMEI Information'.
      • For iOS: Go to 'Settings' > 'General' > 'About', and scroll down to find the IMEI.
    3. Physical check: The IMEI is often printed on the back of the device, under the battery compartment, or on the SIM tray.
    4. Device packaging: The IMEI number is usually also printed on the phone's original packaging box.

    How does the 3G shutdown affect my 3G-only device?

    4G & VoLTE FAQs

    What is VoLTE?

    What is VoLTE?

     

    VoLTE enables compatible handsets to make voice calls via the 4G network. VoLTE was out along-side WiFi Calling and has been available to all services since December 2022.

    What is VoLTE?

    • VoLTE (Voice over LTE) allows you to make voice calls via the 4G network. 
    • Prior to VoLTE, voice calls could only take place on the 3G network.

    What are the benefits?

    VoLTE is the next step in voice calling technology, so there are many benefits, including:

    • Clearer calls with reduced background noise
    • Faster call connections
    • Reduced dependency on the 3G network for making and receiving calls

      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:

      1. Visit your handset manufacturer's website and check the network specs for your specific handset.

      2. Ensure your handsets software is up to date and update if necessary.

      3. 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?

      • VoLTE calls are included as part of the call inclusions for Mobile Plan customers, and are charged at the standard call rate for PAYG customers.
      • VoLTE calls will not consume any of your mobile data.

      Can I still call 000 on VoLTE?

      Yes, calls to 000 will function as normal.

      What does 4G non-VoLTE mean?

      Important update: Following ACMA regulations, 4G phones without VoLTE capability were blocked from the network after 28 October 2024, as they are unable to make emergency calls over 4G.

      Understanding 4G non-VoLTE

      For mobile phones
      A 4G non-VoLTE phone can connect to 4G networks for data services, providing fast internet speeds for downloads and streaming. However, these devices cannot make voice calls over 4G and must switch to 3G for any voice calls, including emergency calls.

      Because these phones rely on 3G for voice calls and cannot make emergency calls over 4G, they were blocked from the network after the 3G shutdown.

      For non-calling devices
      Many devices like tablets, IoT sensors, or data modems are designed for data-only use and don't include voice calling capabilities. These devices don't require VoLTE support, and if they're 4G capable, will continue working normally after the 3G shutdown.

      Impact after 3G shutdown

      Mobile phones
      4G non-VoLTE phones will be blocked from the network completely. This is because they cannot make emergency calls over 4G, which is now a regulatory requirement. These devices must be replaced, regardless of their data capabilities.

      Data-only devices
      If your device only uses data and doesn't make calls (like a tablet or IoT sensor), it will continue working normally as long as it supports 4G. These devices aren't affected by the VoLTE requirement since they don't make calls.

      Required action

      For phones:
      You must upgrade to a device that supports 4G VoLTE and can make emergency calls over 4G. Ensure any new device is compatible with current network bands.

      For data-only devices:
      No action is needed if your device supports 4G. Only devices that are 3G-only need to be upgraded.

      Check your device by texting '3G' to 3498 for specific guidance on upgrading requirements.

      What is WiFi Calling?

      WiFi Calling will enable compatible handsets to make voice calls via WiFi connection.

      WiFi Calling is currently being being rolled out along-side VoLTE and will be made available to all services by the end of December 2022.

      What is WiFi Calling?

      WiFi Calling (sometimes referred to as VoWiFi or Voice over WiFi) will allow you to make voice calls over a compatible WiFi connection.

      If your connected to a compatible WiFi Connection, and WiFi Calling is enabled on your handset, your voice calls will begin going via WiFi by default.

      What are the benefits?

      WiFi Calling is the next step in voice calling technology, so there are many benefits, including:

      • Clearer calls with reduced background noise

      • Faster call connections

      • Reduced dependency on the 3G and 4G networks for making and receiving calls

      How do I start using WiFi Calling?

      To begin using WiFi Calling you will need a device which is WiFi Calling capable.

      To check if your handset is compatible, there are a few things you can do:

      1. Visit your handset manufacturer's website and check the tech specs for your specific handset.

      2. Ensure your handsets software is up to date and update if necessary.

      3. 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.

      How am I charged if I use WiFi Calling?

      WiFi Calling is included as part of the call inclusions for Mobile Plan customers and are charged at the standard call rate for PAYG customers.

      Calls made using WiFi Calling will consume a small amount of data (approx. 100-120kbps of bandwidth). 

      Any data consumed as a result of WiFi Calling will come out of the data allowance of the WiFi network that you are using.

      Is WiFi Calling secure?

      Yes, calls made over WiFi are protected by the same secure industry standards as other mobile calls.

      Can I still call 000 using WiFi Calling?

      Yes, calls to 000 will function as normal.

      Can I SMS over WiFi?

      No, only voice calls are included as part of WiFi Calling.

      Can I use WiFi Calling on any WiFi connection?

      The ability to make voice calls over WiFi is something that the owner of the WiFi network controls.

      If you are ever unable to use WiFi Calling, and your handset is compatible and capable, then it is likely that the owner of the WiFi network that you're connected to is not allowing WiFi Calling to be done on their network.

      Can I use WiFi Calling when I’m overseas?

      As long as you’re connected to a compatible WiFi network overseas, you will be able to make and receive voice calls at your standard rate; as if you were still in Australia.

      Be careful, though. If you lose connection to the WiFi network whilst on a call your handset may automatically connect to the local mobile network and you will begin being charged at standard international roaming rates.

      What is WiFi-SMS/MMS

      WiFi-SMS and WiFi-MMS, also known as SMSoIP (SMS over Internet Protocol) and MMSoIP (MMS over Internet Protocol), allow you to send and receive text and multimedia messages over WiFi instead of the mobile network. This enhancement is crucial as we moved away from 3G networks on 28 October 2024.

      How to use WiFi-SMS

      To use WiFi-SMS, you need:

      • A compatible VoLTE/4G Voice smartphone
      • Latest software updates installed
      • WiFi Calling enabled
      • Connected to a compatible WiFi network

      Enabling WiFi-SMS

      For iPhones:

      1. Go to Settings > Mobile > WiFi Calling and turn it on.
      2. Go to Settings > Messages, turn iMessage off and back on.

      For Android:

      1. Open the Phone app and go to Settings.
      2. Turn on WiFi Calling.

      Benefits of WiFi-SMS

      • Send/receive texts over WiFi without mobile signal.
      • Avoid SMS charges when travelling and using WiFi.
      • Keep messaging after the 3G shutdown in 2024.

      Charges

      When using WiFi-SMS, you're charged standard rates based on the number, not roaming rates. So even overseas (when using WiFi-SMS only), texts to Australian numbers are charged at local rates.

      Please note that while minimal, broadband usage for this service will count towards your data allowance.

      Compatible Devices

      Most recent smartphones with VoLTE support (required for post 3G-shutdown) should work with WiFi-SMS. Check your device specs for clarification.

      • Check your device specs on the manufacturer’s website for clarification.

      My device Is 4G, but I received a notification about the 3G closure. Am I impacted?

      Important: Having 4G capability alone isn't enough to ensure your device will work after 3G shutdown commenced on 28 October 2024.

      Why you received a notification
      If we've contacted you about the 3G closure notifying you about an impacted device, our network data likely indicates that a device on your account either:

      • Lacks VoLTE (HD calling) capability
      • Currently makes emergency calls over 3G
      • Needs software updates to enable VoLTE

      Understanding VoLTE requirements
      A 4G device must have VoLTE (Voice over LTE or HD calling) capability to make calls after the shutdown. Without VoLTE, mobile phones are blocked from the network, even if it can connect to 4G for data.

      For calling devices (phones)
      Your device needs:

      • 4G or 5G data capability
      • VoLTE support for voice calls
      • Ability to make emergency calls over 4G

      For non-calling devices
      If your device only uses data (like tablets, dongles or IoT devices), it only needs 4G capability to continue working after the shutdown. VoLTE isn't required for devices that don't make calls.

      Checking your device
      Text '3G' to 3498 to check if your device needs:

      • A hardware upgrade
      • Software updates
      • Settings changes

      This will help you understand exactly what action you need to take after the shut down date.

        Will I have to change my handset settings to access VoLTE (HD calling)?

        Important: Given 3G shut down on 28 October 2024, your device must support emergency calling over 4G VoLTE or it will have been blocked from the network. This capability is built into the device hardware - it cannot be enabled through settings if your device doesn't support it.

        Device capability
        VoLTE support is hardware-dependent. Your device either:

        • Has VoLTE capability built-in, or
        • Doesn't support VoLTE and needs replacement

        Emergency calling requirement
        The ability to make emergency calls over 4G VoLTE is:

        • A physical hardware feature
        • Cannot be added through settings
        • Required to continue using the network after shutdown

        Network activation
        If your device supports VoLTE, it typically activates automatically once enabled at the network tower. Some devices may need:

        • Settings adjustments
        • Firmware or software updates
        • A restart/power cycle

        Device settings location

        For iPhone:
        Settings > Mobile Data > Mobile Data Options > Voice & Data > select 4G, VoLTE On

        For Android:
        Settings > Network & Internet > Mobile Network > Advanced > VoLTE
        (Note: Menu locations may vary by manufacturer)

        Compatibility check
        To verify your device's VoLTE and emergency calling capability:

        • Text '3G' to 3498
        • Check manufacturer specifications
        • Review device documentation

        Remember: If your device doesn't support emergency calling over 4G VoLTE, no amount of settings changes will enable this feature - you'll need to upgrade to a compatible device to continue using after the 3G shutdown.

        Emergency call FAQs

        Will my device be able to call emergency services (000) after the 3G shutdown?

        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.

        My device can't make Emergency 000 calls over 4G (VoLTE). Do I need an upgrade?

        Yes - you must upgrade your device. The ACMA's Emergency Call Service Determination requires all devices to make emergency calls over 4G VoLTE, or they will be blocked from the network.

        Why immediate action is required
        The situation changed from previous advice. It's no longer about losing parts of your service - devices that can't make emergency calls over 4G VoLTE will be blocked from connecting to the network entirely after the 3G shutdown. This means you'll have no calls (including emergency), no text messages, no data services, and no network access of any kind.

        Is my device blocked?
        To validate whether a device has been blocked visit the Telstra Wholesale blocked device checker and enter your device IMEI.

        Network requirements
        Your new device must support 4G VoLTE for regular calls and emergency calling over 4G. It should also be compatible with current network bands for optimal coverage. Without these capabilities, your device won't be allowed to connect to the network after the shutdown date.

        Timing considerations
        3G shutdown has already commenced. Upgrade now to ensure your new device is fully compatible and working correctly as you may have already been exposed to sudden loss of service if your device is impacted.

        Choosing a new device
        When selecting a replacement device, make sure it's purchased from a reputable Australian seller. This helps ensure the device:

        • Supports emergency calling over 4G VoLTE
        • Is compatible with Australian networks
        • Meets all regulatory requirements

        Need help?
        Text '3G' to 3498 to confirm your current device status. This will give you specific advice on whether your current device is able to make calls to emergency services and whether a hardware upgrade is required.
