As mobile networks evolve, older technologies like 3G are being phased out to make way for faster, more efficient networks such as 4G and 5G. Many users are surprised to find that their 4G devices are affected during the 3G shutdown.
If you’re wondering why this happens and how to check if your device is impacted, this guide has all the answers.
Why Are 3G Networks Being Shut Down?
As mobile technology advances, carriers are phasing out older networks like 3G to focus on newer, faster technologies such as 4G and 5G. The 3G shutdown allows carriers to:
Improve Safety Standards: One key reason for the 3G shutdown is to ensure devices meet modern safety requirements. In Australia, phones must support Triple Zero (000) emergency calls over 4G using VoLTE. Devices without this capability, including older 3G and some 4G models, can no longer meet these standards and are no longer usable.
Free Up Spectrum: The spectrum previously used by 3G networks is being reallocated to enhance 4G and 5G coverage and performance, resulting in faster speeds and more reliable connectivity.
While the transition enhances network efficiency and safety, it also means older and non-compliant devices will no longer function.
Why Are Some 4G Devices Blocked Too?
Not all 4G devices meet the requirements necessary to function after the 3G shutdown. A key factor is whether the device supports Voice over LTE (VoLTE), which is essential for making voice calls over 4G networks.
Triple Zero (000) Safety Standards
One critical reason devices are blocked is to ensure compliance with Australian safety regulations. Phones must support Triple Zero (000) emergency calling over 4G (via VoLTE). This is a legal requirement for all phones sold in Australia to ensure your safety in the event of an emergency.
Devices That May Be Blocked:
Older 3G Handsets:
These rely entirely on 3G networks for voice and data and are now obsolete.
4G Devices Without VoLTE:
Without VoLTE, these devices cannot make voice calls over 4G networks, including emergency calls.
Imported or Grey-Market Devices:
Some newer 4G and 5G phones purchased overseas or through retailers selling imported devices may not meet Australian standards, including Triple Zero (000) calling via VoLTE.
How to Check If Your Device is Impacted
To ensure your phone will continue to work after the 3G shutdown, follow these steps:
1. Check for VoLTE Support:
In Phone Settings: Go to Settings > Mobile Network > VoLTE or Advanced Calling. If you can enable VoLTE, your device supports it.
Carrier Compatibility: Visit your carrier’s website to see a list of VoLTE-compatible devices.
For additional instructions, visit this Optus support page to learn how to enable VoLTE or confirm its availability for your phone.
2. Verify Emergency Call Support:
Confirm with your device’s manufacturer or carrier that your phone supports Triple Zero (000) calling over 4G, a requirement for all phones used in Australia.
3. Confirm Network Band Compatibility:
Check if your phone supports the 4G LTE bands used by your carrier. Devices that lack support for certain bands may experience limited functionality or be blocked.
What Can You Do If Your Device Is Blocked?
If your phone is affected by the 3G shutdown, you have a few options to stay connected:
Upgrade to a Compliant Device:
Look for phones that support VoLTE and meet Australian safety standards, including emergency calling requirements.
Check for Software Updates:
Some devices may need a firmware update to enable VoLTE. Check with your manufacturer or carrier for any available updates.
Contact Your Service Provider for Support:
Reach out to your mobile provider for assistance. They can confirm your device’s compatibility, advise on any solutions, or recommend the next steps to ensure uninterrupted service.
Conclusion: Stay Ahead of the Transition
The 3G shutdown is a necessary step towards enhancing mobile networks, but it also highlights the need for devices to meet modern safety and compatibility standards. Even 4G and 5G devices may be affected if they lack VoLTE or don’t comply with Australian regulations, such as Triple Zero (000) emergency calling support.
