Why we like it

We looked at SIM-only plans that cost $25 a month or less. SpinTel came out on top. It won Best Value Prepaid Mobile Provider at the 2026 Finder Mobile Awards. Plus, you’ll save $48 over 6 months with its latest offer.

Pros

  • Even without discounts, the ongoing price still stacks up well against our $1 per GB benchmark.
  • The plan includes $50 worth of international call credit.
  • Option to sign up with an eSIM if you have a compatible handset.
  • You can use live chat to contact customer support if you don’t want to call.

Cons

  • The price will revert to $22 a month after 6 months.
  • 4G and 5G download speeds are capped at 100Mbps. However, this is more than enough for streaming, gaming, and using apps on your mobile without any issues.
  • You will be charged $10 per GB if you go over your data allowance. Once you hit 10GB, your data use will be blocked. You can disable this in your account settings.

  • You can make unlimited international calls and texts to 42 selected countries.
  • Bundle mobile and internet with amaysim and save $10 a month on broadband.

  • 5G download speeds are capped at 200Mbps, but this is fast enough for online activities on your phone.

Why we like it

We looked at 365-day mobile plans that cost $350 or less and found Lyca Mobile's Medium Long Term plan to be the clear winner. It works out to $12.50 a month for 30GB, which is pretty great value when you break it down over the year. Lyca Mobile also won Best Long Expiry Prepaid Mobile Provider at the 2026 Finder Mobile Awards.

Pros

  • Includes unlimited international calls to 35 selected countries.
  • Access to Vodafone’s 4G and 5G networks. Not many long-expiry plans in our database include 5G access.
  • You can rollover up to 500GB of unused data.

Cons

  • The price will revert to $240 per recharge after 360 days. The expiry length is just shy of a full year. You can easily switch to another provider for a new deal.
  • Unlike some long-expiry plans, Lyca Mobile splits its data into 30-day blocks. It’s still a generous allowance, but worth noting if your usage changes throughout the year.

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.
