Australian Mobile Phone Networks and Retailers

There are three Australian mobile networks in Australia – Telstra, Optus and Vodafone. Collectively these are sometimes referred to as the ‘Big Three’. There are also many smaller retailers that offer mobile services to customers. In the market these retailers are called Mobile Virtual Network Operators or MVNOs.

What is the difference between the big networks and MVNOs?

The three big networks build and maintain their own mobile infrastructure while MVNOs do not. Instead, MVNOs bulk-buy mobile services from one or more of the big networks and sell them on to their customers. This means all the smaller operators operate under one or more of the Big Three.

As a customer you can buy mobile phone plans either directly from one of the big networks or from a retailer / MVNO. Both offer Post Paid Plans and Pre Paid Plans, although not all retailers include devices in their plans.

Network frequencies – 3G, 4G, 5G

The big networks operate on highly regulated frequencies – which are essentially spectrum blocks purchased from the government. When you hear someone say 3G or 4G they are referring to mobile spectrums or frequencies, with the ‘G’ standing for ‘generation’.

2G is old technology and all three networks have switched it off. 3G and 4G are currently the most widely used. 5G is the latest generation technology which you’ve probably been hearing about. Telstra is in the process of rolling out 5G, which should mean greater capacity and faster speeds for its users.

Not all mobile devices support all frequencies, so it’s important to ensure your phone matches network bands in your region. This means if you are using a very old 2G phone or one from overseas it may work for calls and texts but not for data.

These days however it’s generally quite easy to switch between providers without too much hassle. You will however need to make sure your phone is unlocked from your current provider before switching.


Telstra is Australia’s largest telecommunications provider, offering over 99% coverage across Australia. It utilises 3G and 4G connection technology but is now moving onto 5G.

Telstra provides parts of its 3G and 4G network space to its MVNO partners through its wholesale arm. This can result in a difference in speeds and coverage between a direct Telstra plan and one purchased through one of its MVNO retailers.


Optus is number two in terms of size. It uses 3G and 4G, covering 98.5% of Australia. While Optus plans tend to be slower than Telstra’s in terms of speeds, this is usually reflected in its lower pricing structures.

Optus offers its full 4G network to its MVNO partners. This means there should not be any real difference between Optus and its MVNO partner plans in terms of connectivity and speeds.


Vodafone also uses 3G and 4G, covering around 96% of Australia. The company claims its longer spectrum blocks allow devices on its network the advantages of wider bandwidth.

Vodafone offers its full network services to a handful of MVNOs.

MVNOs / Retailers

The big networks and MVNOs or retailers operate independently in a commercial sense. This means when MVNOs buy network services from one or more of the big networks, they are then free to set their own prices.

The MVNO market is very competitive, which means they will often cut prices and offer some fantastic deals and specials for customers. This in turn means when it comes to seeking out the best mobile plans to suit your needs, the world is pretty much your oyster!
