3G shutdown FAQs
Why do the new emergency calling rules mean some devices were blocked?
BackgroundOn 24 October 2024, the Australian Communications and Media Authority (ACMA) issued the Telecommunications (Emergency Call Service) Amendment Determination 2024 (No. 1). This regulation required mobile network providers to block phones that cannot make emergency calls over 4G VoLTE after the 3G shutdown. This moves beyond previous network shutdown arrangements to make this a legal requirement, ensuring all connected mobile phones can access emergency services for public safety reasons. Network changesThe 3G network shutdown commenced on 28 October 2024. From this date, irrespective of regular call or data capability, the new ACMA amendment required that all mobile phones must be able to make emergency calls over 4G VoLTE to connect, and maintain connection with the network. This capability is a hardware feature of the device - it cannot be added through settings or updates. Device requirementsMobile phones must support 4G VoLTE for all calls, and permit emergency calling over 4G. Non-calling devices (like tablets or IoT sensors) only need 4G data compatibility as they are not intended to primarily be calling devices. For existing customersIf your current mobile phone is changed or becomes unable to make emergency calls over 4G VoLTE at the hardware level: Device compatibility is checked automatically and ongoing by the network Incompatible phones will not be allowed to connect The service itself is unaffected and can be restored by switching to a compatible device For new servicesWhen activating a new service: Device compatibility will be checked at the network level upon connection Incompatible phones won't be allowed to connect The service itself is unaffected and can be activated by using a compatible device Taking action Text '3G' to 3498 to check currently connected device status To validate whether a device has been blocked visit the Telstra Wholesale blocked device checker and enter your device IMEI If affected, upgrade to a 4G VoLTE capable device that makes emergency calls over 4G Outright devices, including low-cost mobile phones are available from many retailers, both online and in store After 28 October 2024 If you change devices on an existing service or attempt to activate a new service and are unable to connect to the network, then try another device as it is possible the device you are attempting to use is blocked due to not supporting emergency calls over 4G. Remember: This is a regulatory requirement affecting all mobile providers. After 28 October 2024, incompatible phones were blocked from connecting to mobile network - services are not impacted and the SIM will connect as soon as it is placed into a compatible device.
Read moreHow are devices that can't make 4G emergency calls blocked after 3G shutdown
From 28 October 2024, new regulations required mobile networks to block devices that cannot make emergency calls over 4G VoLTE. Here's what you need to know about how this works. Understanding device identificationEvery mobile device has a unique IMEI (International Mobile Equipment Identity) number. The first 8 digits of this number form the TAC (Type Allocation Code), which identifies not just the make and model, but the specific variant of your device. Why variants matterThe same phone model might have different versions for different markets. For example: An Australian iPhone variant may support local 4G emergency calling The same model from another market might not Each variant has its own unique TAC Network compatibility varies between variants The blocking processWhen your device tries to connect to the network, it sends its IMEI. Network providers (in ALDI Mobile's case this is the Telstra Wholesale network) maintain a list of TACs that identifies devices unable to make emergency calls over 4G. If your device's TAC is on this list, it will be blocked immediately. ALDI Mobile do not control this list and are not able to add or remove TACs from it. What happens when blocked Your device will display "no service" No calls, texts, or data will work The device cannot be unblocked Moving your SIM to a compatible device is the only solution Restoring serviceTo regain network access: Get a device with a compatible TAC Move your SIM to the new device Service will restore automatically Checking your deviceText '3G' to 3498 to check if your device will be blocked. This check uses your device's TAC to confirm compatibility with Australian networks and emergency calling requirements. Important: Once blocking begins, you won't receive notifications on a blocked device. Check compatibility and upgrade before the shutdown date. After blocking begins, if a device doesn't connect that previously did, it is likely incompatible and the SIM should be moved to a compatible device to connect. It's important to note that you service remains active and won't be impacted by your device status.

Read moreWhat if my device has limited 4G band coverage and/or missing Band 28?
Mobile networks operate on specific frequencies called "bands". Each tower broadcasts signals on various bands, and your device must support at least one to connect. Different bands have unique characteristics affecting coverage, building penetration, and data capacity. Significance of Band 28 Band 28 (700 MHz) is crucial on the Telstra Wholesale network that ALDI Mobile uses because it has: Extended coverage: Provides better coverage in rural and remote areas. Building penetration: Improved indoor reception. Network efficiency: Key for balancing network load and performance. Implications of limited 4G band support Coverage issues: Potential signal loss in areas where only unsupported bands are available. Compromised indoor reception, especially in buildings with thick walls. Reduced network performance: Possible slower data speeds or less reliable connections. Future-proofing concerns: Critical as 3G networks were shut down from 28 October 2024). Recommended actions Check your device specifications: Review your device's supported 4G bands in its manual or online specifications. Use our coverage checker: Review the coverage map on our website. Consider an upgrade: If experiencing consistent coverage issues, consider a device with wider 4G band support. Network details To fully leverage the Telstra Wholesale network capabilities, ensure your device supports the bands used in your area: Required primary bands: 4G: 700MHz (Band 28) - Main coverage band 5G: 3.6GHz (Band n78) - Main 5G band Additional capacity bands (availability varies by location): 4G: 1800MHz (Band 3), 2100MHz (Band 1), 2600MHz (Band 7) 5G: 850MHz (Band n5), 2.6GHz (Band n7), 26GHz (Band n258) Note: Not all frequencies and bands are active in every location. For specific area information, consult the Radio Frequency National Site Archive (RFNSA). For further details about our network coverage, please refer to our coverage map.

Read moreMy 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 requiredThe 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 requirementsYour 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 considerations3G 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 deviceWhen 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.
Read moreWill 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 capabilityMost 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 devicesIf 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 deviceText '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 actionIf 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.

How do I enable VoLTE (4G voice calling) on my device?
To continue accessing the network and being able to make voice calls after 3G shut down on 28 October 2024, devices need to support VoLTE (Voice over LTE/4G voice calling/HD calls). Here are the steps to enable it: Check for software updates First, ensure your device is running the latest software version from the manufacturer. Software updates often enable new features like VoLTE. Android: Open Settings > System > Software update (path may vary) Check for updates and install any available iPhone: Go to Settings > General > Software Update Enable VoLTE in settings Once updated, you'll need to turn on VoLTE in your mobile network settings. The path differs by manufacturer: Android: Open Settings > Network & internet > Mobile network Look for an option like "Enhanced 4G LTE Mode" or "VoLTE" and turn it on iPhone: Go to Settings > Mobile Data > Mobile Data Options Tap "Voice & Data" and select the VoLTE enabled option (e.g. 4G, VoLTE On) Samsung: Tap Settings > Connections > Mobile networks Toggle VoLTE calls Huawei: Tap Settings > Wireless & Networks > Mobile Network Toggle VoLTE calls OPPO: Tap Settings > Dual SIM (or 'SIM card and mobile data' on single SIM models) & Cellular Network Choose SIM 1 or SIM 2 (just SIM on single SIM phones) Nokia: Tap Settings > Network & Internet > Mobile Network > Advanced Toggle Enhanced 4G LTE Mode Motorola: Settings > Mobile network > Mobile data Toggle VoLTE calls Reboot your device After enabling VoLTE, restart your phone to ensure the new settings take effect. If you don't see VoLTE options or have trouble, check your device manufacturer's support for model-specific instructions. Enabling VoLTE will allow you to continue voice calling over 4G after the 3G shutdown, while also accessing data simultaneously, as long as your device supports it. If your device does not have VoLTE capability then it will need to be replaced in order to be able to continue using the service after 3G was switched off.
