What’s happening to the 3G mobile network in Australia and how will it affect you? Read on to find out more!

Telstra, Optus & Vodafone have all started shutting down spectrum bands (parts) of their 3G mobile services across Australia.

Mobile phone networks operate on many different frequencies, spectrums and bands in just the same way different radio stations do.

The difference here is that mobile phone technology is always evolving and advancing at a fast pace. On this basis, our Telco’s are re-farming (converting) their 2100MHz mobile frequency from 3G to 5G however they will still provide a 3G service but only on their remaining available frequency.

Telstra took the lead on 25th March 2019 and shut its 2100MHz mobile network which left their 850MHz network as their primary 3G mobile service. Telstra have confirmed they will switch off the remaining 3G network on 22nd June 2024.

Optus have recently contacted customers advising they will be shutting down their 3G 2100MHz mobile network in April 2022 and it will be converted to 5G in May 2022. Optus will still provide a 3G service on their 900MHz network with no scheduled end date at this stage.

Vodafone progressively closed its 3G 2100MHz mobile network throughout 2019 but still operates a 3G service on their 900MHz mobile network. There is no confirmed timeframe when Vodafone will shutdown their remaining 3G service.

How does this affect you? If you have one of our Chuango G5W alarm systems, there are a couple of options available. You could change your alarm SIM card over to the Telstra 3G 850MHz network or you could upgrade your G5W control panel to our H4-LTE (4G & WiFi) smart home alarm system.

Besides being an upgrade to 4G, the H4-LTE also works via WiFi & Data technology that will provide you with a more advanced and robust security alarm system. In addition, you will always have real time app status of your security.

It is completely up to you whether you change your SIM card or upgrade to our newer Chuango H4-LTE model. All existing wireless accessories are compatible with the upgrade model so there is no need to purchase or replace any wireless accessories.
