Support/FAQs / Telstra 3G mobile exit

Telstra 3G mobile exit has been extended to 28 October 2024.

Telstra is upgrading the mobile network to deliver a better experience for all users. As part of these improvements, the current 3G network will be retired and all users will move to the more modern 4G and 5G network. This will impact Cmobile customers who have a C Blue – Telstra network plan.

The current Telstra 3G mobile network (850Mhz band) will be retired on 28 October 2024. There will be no interruption to 3G services or network coverage prior to this date. After 28 October 2024, the mobile network will only support 4G and 5G devices. Note, your 4G device will need to support 4G band 28 (700MHz) and Voice over LTE (VoLTE) to support voice calls including emergency calling. Most modern smartphones support VoLTE and WiFi calling which uses digital packet technology to route voice traffic and transmit data.

If you have a device that only supports 3G or it is a non-VoLTE capable 4G mobile device, it will cease to operate on the Telstra 3g network after 28 October 2024. You will need to upgrade to a new device that supports 4G VoLTE and 5G networks to maintain your service.

If you are unsure if your device supports 4G or 5G, please contact us at support@cmobile.com.au or call us on 1300 545 000 and we will be happy to help you.
