Australians urged to test mobile phone capability ahead of 3G switchover

Australians can now use a new free online tool to check if their mobile handset will be impacted by the upcoming 3G network switchover.
 
The Australian Mobile Telecommunications Association (AMTA) tool allows consumers to enter their device’s unique IMEI number to see if their handset will no longer have access Triple Zero after both Telstra and Optus plan to switchover to 4G and 5G from 1 September 2024.

The IMEI is a 15-digit serial number for mobile handsets. The new tool, and instruction on how to locate the IMEI, are available at www.3gclosure.com.au.

Customers will not be required to enter any personal information when using the tool.
 
The Government is concerned about a sub-set of 4G enabled handsets that will continue to operate normally for voice, SMS and data after the switchover, but will default to 3G for Triple Zero calls because of manufacturer configuration. This may include older devices and devices purchased overseas.
 
Industry estimates provided to the Government earlier this year suggested the number of impacted devices was around 740,000. Through the Working Group established by the Government, industry now estimates 283,000 devices will be impacted.
 
Telstra and Optus customers can already access an SMS tool to check if their mobile handset may be affected.  Customers can text ‘3’ to ‘3498’ and the service will automatically respond with advice on whether or not their device is affected.
 
Telstra’s 3G switch off has been delayed until 31 August 2024. Optus is planning to switch off its 3G network from 1 September 2024. TPG Telecom/Vodafone has already switched off its 3G network. Customers may still be relying on Telstra and Optus’ 3G networks for Triple Zero and should not assume their device is unaffected.

Quotes attributable to the Minister for Communications, the Hon Michelle Rowland MP:
 
“The Albanese Government supports the 3G switchover, but it needs to be done in a safer way.
 
“All Australians should be aware that some 4G phones are configured by their manufacturer to default to 3G for Triple Zero calls. That means these devices will appear to work normally after the switchover, until Australians can least afford to realise there is an issue.
 
“This new industry tool is another useful way Australians can check to see if their device may be impacted.
 
“If you have been contacted by your mobile phone provider alerting you of impact to your service, it is important you respond and take action. "
