This product requires a 3G GSM signal. Although Telstra and Vodafone have already started phasing out parts of their 3G networks for older devices, at this stage, no one has confirmed any specifics around when 3G will be switched off entirely. Telstra  will continue to operate 3G services on its 850MHz spectrum until June 2024. Optus has yet to provide any timeline for when it intends to shutdown its 3G network. Unlike Telstra and Vodafone, it isn't currently phasing out any of its 3G network frequencies. Once the 3G network is turned off entirely, the communicator in this product will need to be upgraded to 4G. As of July 2020, when this paragraph was written, there were no 4G units available for the product, but they are in development and will be available once testing has been completed by the manufactures.
