Our GSM network provides coverage to more than 96 per cent of the Australian population and more than 600,000 square kilometres.

GSM is a great mobile phone network for customers in capital cities with excellent in-building coverage, metropolitan areas and for international travellers.

Mobile phone usage can sometimes be restricted or even impossible inside certain buildings, structures and some locations, notably within capital cities. Telstra's GSM network has an extensive range of base stations inside many buildings and structures to help provide coverage within some of these difficult areas.

GSM network users can also take advantage of information and data services via GPRS. With a GPRS capable mobile phone you can access information services, the internet, send and receive emails, and more.

GPRS coverage is available over the same coverage area as GSM. Find out more about GPRS.

And with extensive international roaming capability in more than 130 countries (including nearly 50 with GPRS), GSM is also a great choice for international travellers, helping to keep you in touch when travelling overseas.
