Telstra operates the largest GSM, CDMA and 3G mobile telephony networks in Australia.

MobileNet services are available in post-paid and prepaid payment types. Telstra provides GSM, NextG and CDMA (until early 2008) Prepaid Mobile services, via Telstra Pre-Paid. This service has previously been branded under a number of different names, including "Zip", "U", "communic8", and "Telstra Pre-Paid Plus".

In late 2005, Telstra announced that it would replace its CDMA network with a new UMTS network incorporating HSDPA running at 850 MHz, later to be known as Next G. 850 MHz was chosen over the usual 3G 2100 MHz as it can cover much greater geographic distances. This network was implemented under contract by Ericsson as part of a project internally dubbed "Jersey" and launched on 6 October 2006. The CDMA network will continue to run until 28 January 2008 [5], however, migration onto the Next G network has already begun for customers who are pre-paid, still under contract, or have expiring contracts.

Rural Telstra exchange building, located in Karawinna, Victoria.The current 3G WCDMA/UMTS network operating on the 2100 MHz band is provided by a joint venture between Telstra and Three, whereby Telstra acquired half of Three's radio network and pays half of expansion/maintenance costs. This has enabled Three customers to gain access to the GSM network where 3G coverage is non-existent via a reciprocal agreement.

Telstra was one of the only regional providers to provide i-mode services (running on GSM/GPRS and 3G 2100 MHz WCDMA on one particular handset), licensed from NTT DoCoMo. Telstra no longer sells i-mode, and this service is no longer available to existing customers as of December 10, 2007, with current customers being able to recontract with a new handset without incurring early termination charges. With the launch of the Next G network, Telstra now offers more advanced value added services such as mobile TV (branded Foxtel), and other generic internet services (BigPond Mobile, formerly Telstra Active).

Historically, Telstra attempted to break through to the value added services such as video streaming and content via its CDMA/1xRTT network with a service called Telstra MobileLoop. This offering was not commercially successful, and was abandoned in favour of a GSM i-Mode offering, and later Telstra Active 3G services which has now become Bigpond Mobile services and operates on the GSM, 3G 2100 and Next G networks. Telstra also is the only Australian mobile network provider supporting EDGE.
