As Australia prepares for the nationwide shutdown of the 3G network by major telecommunications providers from October 28, Diabetes Australia is reminding people with diabetes and their carers to check whether their medical devices, such as continuous glucose monitors (CGMs), rely on 3G connectivity.

The shutdown may disrupt the ability of some devices to send or receive data. However, it’s believed that most Australians’ glucose data transmitters are now connected by Bluetooth.

CGMs can use mobile networks to transmit blood glucose data or alerts to smartphones, healthcare providers, or caregivers. If these devices are only compatible with 3G technology, the loss of service could lead to delays in receiving critical health information or warnings of high or low blood glucose levels.

For a small number of people whose devices are not connected to Bluetooth and who will be affected by the shutdown, this could present a risk.

Those who are unsure about their equipment’s connectivity are encouraged to check the compatibility of their device and contact their healthcare providers or device manufacturer for guidance on upgrading if necessary.

Australia’s Therapeutic Goods Administration (TGA) advises that devices which may be impacted by the decommissioning of the 3G network include:  

• Glucose data transmitters  
• Pacemakers and implantable cardioverter defibrillators (ICD) 
• CPAP therapy machines  
• Cardiac resynchronisation therapy monitoring devices 
• Telehealth devices  
• Wearable health monitors  

Others not regulated by the TGA but also potentially impacted by the shutdown include: 

• Personal safety pendants 
• Fall detection systems  
• Home security alarms  
• GPS tracking devices  
• Automated medication dispensers  

The transition to newer 4G and 5G networks will improve connectivity and offer faster data transfer. However, people with older devices that are not compatible with these networks may need to upgrade to avoid disruptions.

To avoid potential issues, Diabetes Australia recommends that people review their device specifications, reach out to their device manufacturers, and ensure they have access to alternative methods for managing their diabetes, such as manual glucose checks or backup devices.
