Like most of Australia, the South Australian population is clustered around the coastline, and with it, the majority of the state's mobile phone towers.
With just 1.7 people per square kilometre of land, South Australia has one of the lowest population densities in the country -- just marginally higher than Western Australia and the Northern Territory. This has a serious impact on the size of the network the carriers are likely to invest in.
There is some coverage in regional parts of the state, like Coober Pedy and around Lake Eyre, but it is pretty patchy.
Perhaps the greatest shame is that there is very little Vodafone coverage outside of Adelaide. This means lower competition, and higher costs for South Australians.
Coverage in SA at a glance
What stands out
- At least Adelaide is covered.
- Telstra offers some regional coverage, but not a whole lot.
What could be improved
- More of the major roads heading north to be have coverage.
- Very little competition means more people paying a premium for Telstra services.

Big Carriers vs. Small Carriers in SA
Did you know that there are dozens of small carriers that run on the major networks, but charge a fraction of the price for service? These companies are known as Mobile Virtual Network Operators, MVNOs for short. MVNOs purchase network service from the major providers at wholesale prices, then pass the savings on to consumers.
