Our top pick was chosen based on the plan with the highest value score from a Finder partner.
We looked over 300 SIM-only plans in our database and attached a value score to each plan we compared for each category, looking at factors such as price, daily cost per gigabyte, network coverage and any applicable download speed caps, with the provider having the highest score coming out as the winner.Keep in mind, we only looked at Finder partners but they were still chosen for our best guide keep a rigid methodology in mind.Here’s a rundown of exactly how our value-scoring system works:
Cost per gigabyte. This is calculated by taking the price of the plan over 12 months divided by the amount of data (GB). The price includes any promotional offers.
Network coverage. We awarded scores depending on how wide the network coverage is across Australia.
Data rollover. We weight providers that offer data rollover higher than those that don't have this feature.
International calls. We weight providers that offer data rollover higher than those that don't have this feature. This includes those that offer unlimited calls or credit/minutes for international purposes.
Wi-Fi calling. We give weights to providers that offer Wi-Fi calling higher than those that don't have this feature.
We then assigned a weight to each of the factors in order to calculate a value score. Price and data are given the highest weighting.

How do you find the best SIM only plan?
There's no one-size-fits-all approach to finding a SIM only plan. Your budget and data needs can vary depending on how you use your phone. Here are a few things to consider apart from price alone:
What network are you after?
There's no doubt Telstra's network reigns supreme in coverage. It reaches the most number of Aussies, especially if you're living outside the metro areas. That being said, if you're staying in the city, you could be better off with the lower price tags of plans on the Optus or Vodafone network.
How much data do you need?
Australians download around 12.8GB of data on average every month according to the ACCC. We recommend finding out how much data you use and matching a plan that fits the bill accordingly. You don't want to be paying more for data that's going to waste and to rack up any excess charges because you signed up to a much lower limit.
What plan length works best for you?
While most people are familiar with month-to-month mobile plans, long-expiry plans also exist that could help you save money by paying for your plan usage upfront. These plans last for 90–365 days but just remember you'll need to be happy to stick it out with that one provider for 3–12 months.
Do you want a no-frills plan or one packed with features?
The cheapest plans are usually those with just calls, texts and data. But if that's all you need anyway, you might as well grab these simple plans for a lower cost. If you're looking for more value, consider extra features such as international calls, data rollover or Wi-Fi calling.

Finder is one of Australia's leading comparison websites. We are committed to our readers and stand by our editorial principles.
We try to take an open and transparent approach and provide a broad-based comparison service. However, you should be aware that while we are an independently owned service, our comparison service does not include all providers or all products available in the market.
Some product issuers may provide products or offer services through multiple brands, associated companies or different labeling arrangements. This can make it difficult for consumers to compare alternatives or identify the companies behind the products. However, we aim to provide information to enable consumers to understand these issues.
We make money by featuring products on our site. Compensation received from the providers featured on our site can influence which products we write about as well as where and how products appear on our page, but the order or placement of these products does not influence our assessment or opinions of them, nor is it an endorsement or recommendation for them.
Products marked as 'Top Pick', 'Promoted' or 'Advertisement' are prominently displayed either as a result of a commercial advertising arrangement or to highlight a particular product, provider or feature. Finder may receive remuneration from the Provider if you click on the related link, purchase or enquire about the product.

Where our site links to particular products or displays 'Go to site' buttons, we may receive a commission, referral fee or payment when you click on those buttons or apply for a product.
When products are grouped in a table or list, the order in which they are initially sorted may be influenced by a range of factors including price, fees and discounts; commercial partnerships; product features; and brand popularity. We provide tools so you can sort and filter these lists to highlight features that matter to you.
