What is VoLTE and what do I need to do before the 3G closure? 

Voice over LTE (VoLTE) lets you make phone calls over the 4G (LTE) network. Your mobile device will use 4G to make and receive these calls in areas where 4G (LTE) is available. When Telstra’s 3G network closes from 28 October 2024, VoLTE will be required to make or receive phone calls on the Telstra mobile network. It’s important to note that: 

• 3G phones do not have VoLTE; and 

• not all 4G phones have VoLTE and/or are compatible with the Telstra network. 

If you have a 3G mobile device, you must upgrade to a 4G/5G mobile device that is VoLTE capable and compatible prior to 28 October 2024.
