How to Determine if Your Device is Affected by the 3G Network Shutdown

Australians apprehensive about the imminent shutdown of 3G networks now have a solution. The Australian Mobile Telecommunications Association (AMTA) has rolled out an online tool called “Check My Device,” designed to help users determine if their mobile phones will remain functional on newer networks, including maintaining access to the crucial Triple Zero emergency service.

Hosted at, the tool supports 11 languages, such as Mandarin, Arabic, Greek, and Hindi, catering to Australia’s diverse demographics. It allows users to enter the 15-digit International Mobile Equipment Identity (IMEI) number of their phone—accessible by dialing *#06#—to instantly find out if their device will work after the 3G network is discontinued.

If a device indicates a “CHECK” status, the AMTA strongly recommends contacting the service provider to confirm the device’s ability to make emergency calls post-3G network shutdown. Additionally, Telstra and Optus customers can directly verify their phone’s functionality by texting “3” to “3498.”

When considering the purchase of a new phone, AMTA advises consumers to check the IMEI number with the seller to ensure the device will continue to operate post-3G shutdown. The association also cautions against buying “grey-import” devices, which might not support emergency calls once 3G services end, and stresses the importance of ensuring that the device is not blocked or restricted in any way.

Australia is phasing out its 3G networks in stages, with TPG Telecom’s Vodafone network being the first to close in January 2024. Following that, Telstra is set to decommission its 3G services by August 31, 2024, with Optus beginning its shutdown in September 2024.

Louise Hyland, CEO of AMTA, highlighted the critical nature of this transition, stating, “Devices that depend on 3G for voice calls will no longer be able to make any calls, including emergency calls to Triple Zero, once the 3G networks are shut down in Australia. This includes some 4G devices as well. ‘Check My Device’ offers a straightforward way for users to ensure their mobiles are ready for the network switch.”

This new initiative aims to ensure all Australians remain connected and have access to essential services as the telecommunications landscape transitions away from older technologies.
