Exploring Australia? Here’s the Best SIM Card to Keep You Connected
The best SIM card in Australia can make all the difference when staying connected during your trip.
You’re not alone if you’re unsure about which SIM card and network to use while travelling in Australia.
Choosing the right SIM card can feel overwhelming, with multiple options and varying coverage across urban and rural areas.
In this article, I’ll explain the best options, drawing from years of experience using different networks while travelling around Australia.
Whether after great coverage or affordable pricing, this guide will help you find the perfect SIM card for your needs.
What is a SIM Card?
A SIM card, or Subscriber Identity Module, is a tiny chip that connects your phone to a mobile network.
It’s like a key to unlocking your phone’s ability to make calls, send texts, and use data.
Each SIM is tied to a specific phone number and plan, securely storing your identity on the network.
There are different types of SIM cards:
- Standard SIM: The original size is now outdated.
- Micro SIM: Popular in older smartphones.
- Nano SIM: The smallest and is used in most modern devices.
- eSIM: A digital version that doesn’t require a physical card and can be activated remotely.
Getting a SIM Card in Australia
Buying a SIM card in Australia is easy and flexible, whether staying for a few days or planning a longer visit.
The major providers are Telstra, Optus, and Vodafone, each offering different coverage and price points.
Telstra is known for excellent coverage, especially in rural areas, while Optus and Vodafone are great for cities and budget options.
SIM cards can be bought in supermarkets like Woolworths and Coles, electronics stores like Kmart, or even convenience stores and petrol stations.
SIM cards are also available online for delivery. Prepaid SIMs are popular because they allow you to top up as needed.
If you have an eSIM-compatible device, you can skip the physical card and activate your plan digitally by scanning a QR code from the provider.
Just check network coverage for the areas you plan to visit.
Cost of SIM Card in Australia
Finding the cheapest SIM card in Australia is simple. Several budget options are available, whether you need a short-term plan or something more long-lasting.
One excellent option is Catch Connect, which offers a 365-day plan with 120GB for just $109.
This plan operates on the Optus network, and Catch Connect often offers discounts of up to 25%, making it even more affordable.
Just be mindful to renew on time to avoid losing any unused days.
However, Catch Connect doesn’t offer international calls or roaming, so it’s perfect if you only want local use.
If you’re looking for prepaid flexibility, Aldi Mobile offers various plans using parts of the Telstra network.
Their plans range from $29 for 25GB of data to $59 for 175GB, with 5G access and unlimited data rollover.
Aldi also offers family plans, like $55 for 50GB of shared data or $125 for 150 GB. Aldi’s $5 starter pack is ideal for those wanting a simple, pay-as-you-go option.
Dodo Mobile offers affordable plans and flexible postpaid options.
The $23 plan includes 15GB of data, a $100 international call credit, and data banking, while the $38 plan offers 60GB with a $400 international call credit.
Dodo also uses the Optus network and has data banking that allows you to roll over unused data, up to 500GB.
Moose Mobile is another great budget option using the Optus network.
Moose is known for its clear billing and no hidden charges, making it a good choice if you want simplicity.
Moose’s plans range from low-data options for light users to higher-data plans, but what sets them apart is their easy number transfer and parental control features, which add flexibility and security to their offerings.
With Catch Connect, Dodo Mobile, and Moose Mobile, you can easily find a plan that fits your needs, whether after the cheapest SIM card plan in Australia or a more flexible option with international calling.

eSIM vs. SIM Card: A Comparison
Both eSIM and traditional SIM cards connect your device to a mobile network but differ in form and functionality.
A SIM card is a small, removable chip that stores your mobile information and must be manually inserted into your phone.
It’s been the go-to option for years and works with most devices. Swapping the card makes it easy to switch between phones.
On the other hand, an eSIM is embedded directly into your device. No physical card is needed; switching plans or carriers can be done digitally without removing anything.
eSIMs are perfect for travellers since they let you activate local plans remotely, but they aren’t yet available on all devices.
Key Differences:
- Activation: A physical SIM requires manual insertion, while eSIMs are activated remotely.
- Switching Plans: You need to swap SIM cards physically. eSIMs allow switching plans digitally and can store multiple profiles.
- Travel Convenience: eSIMs make it easier to add new plans when abroad without buying local SIMs.
- Compatibility: SIM cards work with nearly every device, but eSIMs are still catching up.
eSIM Benefits:
- Space-saving in devices
- Easier plan switching
- Ideal for travellers
- More secure
SIM Card Benefits:
- Familiar and widely used
- Broader compatibility
- Simple to transfer between phones
