Why we like it

We looked at SIM-only plans that cost $25 a month or less. TPG is our top pick for the month, with its latest offer saving you $75 over 6 months. Plus, you'll also get a $50 digital Visa gift card when you sign up through Finder. TPG was highly commended in the Best Value Prepaid Mobile Provider category at the 2026 Finder Mobile Awards.

Pros

  • The plan includes 100 international minutes and as many texts to 31 selected countries.
  • Option to sign up via an eSIM if you have a compatible handset. This takes the hassle of waiting for a physical SIM card to be delivered.

Cons

  • The price reverts to $25 a month after 6 months. However, it still stacks up well against other plans.

Why we like it

We looked at mobile plans that cost between $25 and $35 a month and come with at least 25GB of data. Dodo’s 40GB plan takes the top spot this month. Its current offer will save you $90 over 6 months, and the ongoing price also compares well against our $1 per GB benchmark.

Pros

  • There are no excess data charges. If you run out of your monthly data allowance, the download speed will simply slow to 256Kbps.
  • Unlimited data banking is available. Your unused data won’t ever go to waste as long as you stick with this plan.
  • Includes $200 worth of international call credit.
  • You can bundle mobile, internet and energy plans to save up to $15 a month.

Cons

  • The price will revert to $30 a month after 6 months.
  • 5G download speeds are capped at 150Mbps, though this should be more than enough for streaming, browsing and gaming.

Cons

  • The monthly price increases to $42 after the first 3 months, while the data allowance drops to 75GB after 6 months.

  • Option to earn 1 Qantas Point for every $2 you spend.

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.

phone with arrows pointing to opposite direction

How much data do you need?

Australians download around 14GB 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.

      Hi Phyllis,

      You can see a range of Optus pre-paid plans here, which currently come with a Finder Reward exclusive offer of a visa gift card. You can review a range of other pre-paid options here from different providers. Select ‘365-days’ in the plan length filter to the left, so see the year-long plans you’re looking for. Hope this helps!

      Hi Elizabeth, it sounds like you’re after an eSIM-compatible plan that can connect to both your iPhone and Apple Watch.

      For our money, Southern Phone’s 20GB plan, which uses the Optus 4G/5G network, offers the best bang-for-buck.

      You can currently get it for just $14 per month for the first 6 months, exclusively through Finder. The price then jumps to $24 per month but don’t stress – there’s no lock-in contract, meaning you can start shopping around before the deal ends.

      The plan comes with 20GB data, unlimited calls & text and $50 international call credit. You can easily sign up for an eSIM via its website.
