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:

mobile network signal

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 10.2GB 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.

Plan length

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.

bulleted list

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.

Alex Holderness

I'd been on a contract phone, well, forever. I used to regularly pay over $80 a month for my phone bill. I took the leap to get a Sim Only and buy a phone outright as i found it easier to manage my bills month to month. I also got a great deal, paying just $15 a month with a Circles offer. I've switched 3 times since then while keeping my phone number, it's allowed me to take advantage of great sign up offers.

Here are some handy tips from our experts for picking the best prepaid plan:

How we researched the best SIM-only plans

  • We looked at SIM-only plans in our database designed for personal use.
  • Other selection criteria to narrow down our shortlist included looking at active Finder partners across the categories which allowed for this.
  • Promotional discounts were also taken into account during scoring.

How does Finder's value scoring system work?

For certain categories, we use a value scoring system to choose the best SIM-only plan by scoring the following factors:

  • Cost per gigabyte. This is calculated by taking the price of the plan over 12 months divided by the amount of data (GB).
  • 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. This includes those that offer unlimited calls or credit/minutes for international purposes.
  • Wi-Fi calling. We weight providers that offer Wi-Fi calling higher than those that don't have this feature.

We then assign a weight to each of the factors in order to calculate a value score. Price and data are given the highest weighting.
