Changes to our earlier 3G network

Mobile services on our earlier 3G mobile network operating on the 2100MHz band – known as 3GIS – will be wound down this Friday 31 August.


We first started contacting people affected by the changes in 2010 – so if you’re one of the last remaining people on the network you’ll probably already have a good idea of how to prepare for the changes.


Most people who remain on the old network use their phone for basic talk and text and you’ll still be able to access these services on your current devices in Telstra’s 2G coverage areas. 


However, if you who surf the internet and don’t have a Next G compatible mobile phone or modem you will likely experience slower data speeds if your continue to use a device that operates its 3G functions only on the 2100MHz band – rather than the 850MHz band used across the Next G network. We’re encouraging these customers to upgrade to a Next G compatible device.


Some people using the 3GIS network actually have Next G® compatible devices -- but their device may set to access the earlier 3G network’s 2100MHz frequency. Often this is because they have previously used their device on another network. If you’re one of these people, all you need to so is switch your network settings to ‘Automatic’ to ensure your device connects with the Next G network following the changes.


If we’ve contacted you and you haven’t yet prepared yourself for the change, here are three things to do:


1. Check that your device is Next G compatible. To continue to access 3G services across Telstra’s national 3G network footprint, customers need both a Next G compatible device and Next G coverage. Customers can check that their device is 850MHz compatible (the primary frequency on which Next G network runs) by using Telstra’s online device identifier tool:


2. Check their device network settings. Some devices currently used on the 3GIS network are actually Next G compatible. However, either because customers have adjusted their settings or because devices were used previously on other mobile networks, they may be set to access the 2100MHz band only. Customers should switch their network settings from ‘3Telstra’ (3G 2100MHz) to ‘Automatic’ to ensure their device connects with the best available network.


3. Give us a call if they have any questions. For more information about these changes or to upgrade to a Next G compatible device,  customers can head to or call us on:
