Check your CGM ahead of 3G network closure

The closure of the 3G network may interrupt the ability of some devices, including continuous glucose monitors (CGMs), to send or receive data. However, most glucose data devices are now connected by Bluetooth.

CGMs can use mobile networks to send 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.

We urge people who are unsure about their device connectivity to check and contact their healthcare providers or device manufacturer for advice on upgrading if necessary.

Impacted devices

According to Australia’s Therapeutic Goods Administration (TGA) the following devices might be impacted by the closure of the 3G network:  

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

Other devices not regulated by the TGA that might be impacted by the shutdown include: 

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

Upgrade where needed

The move to 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 Victoria recommends people review their device connectivity and ensure they have access to backup methods for managing their diabetes, such as manual glucose checks or other devices.
