Why we like it

We looked at 365-day plans priced at $150 or less and found OnePass Mobile’s 200GB Finder Exclusive plan came out on top. Sign up through Finder and you'll pay just $149 on your first recharge. That works out to roughly $12 a month for 17GB, comfortably beating our $1 per gigabyte benchmark. You’ll struggle to find a month-to-month plan that offers the same kind of value.

Pros

  • Get a free OnePass membership as long as you stay on the plan.
  • Earn 5x Flybuys points for every $1 spent on recharge when you link your Flybuys account.
  • You’ll have access to a handy mobile app to help you track data use and manage your plan.
  • Option to contact customer support via its live chat feature or simply by calling.
  • OnePass Mobile was highly commended in the Best Value SIM Only Mobile Provider category at the 2026 Finder Mobile Awards.

Cons

  • The price will revert to $200 from the second recharge.
  • This plan doesn’t include 5G access.

Why we like it

We looked at 365-day plans under $250 with more than 200GB of data and found Lyca Mobile’s Medium Long Term plan to be a standout this month. With the current offer, the cost is about $12.50 a month for 50GB of data in your first 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 roll over up to 500GB of unused data.
  • Option to sign up via an eSIM if you have a compatible handset.

Cons

  • The price will revert to $240 from the second recharge.
  • 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.
  • You’ll get charged extra for using its Multimedia Messaging Service ($0.62 per MMS).

Why we like it

We looked at 365-day mobile plans under $350 with at least 300GB and found Kogan's Extra Large 365 Days Flex plan to be the clear winner. Kogan First members will pay around $17 a month for 42GB. Non-members pay closer to $25 a month, which is still excellent value for the amount of data included.

Pros

  • Kogan Mobile was highly commended in the 2026 Finder Mobile Awards in the Best Long Expiry Prepaid Mobile Provider category.
  • You can sign up via an eSIM if you have a compatible handset.
  • Option to earn 1 Qantas Point for every $2 you spend.

Cons

  • The price will revert to $300 from the second recharge for Kogan First members.
  • This plan doesn’t include 5G access.

Why we like it

We looked at 365-day plans on the Telstra network under $350 and found Boost Mobile’s latest offer topped the list this month. It works out to around $21 a month for 25GB. Boost Mobile is the only smaller provider with full access to the Telstra network. This can make a difference for people living in regional and rural areas.

Pros

  • The plan includes unlimited calls to 20 countries, 3,600 minutes of standard calls to 30 selected countries, and 3,600 standard texts worldwide.
  • You can buy an international roaming pack to use in 42 selected countries.
  • Option to sign up with an eSIM if you have a compatible handset.

Cons

  • The price and data allowance will change to $300 for 240GB from the second recharge.
  • Download speeds are capped at 150Mbps, though this is fast enough for online activities on your phone.

Why we like it

We looked at Optus’s monthly and long-expiry mobile plans and found its 186-day option offers excellent value this month. You'll pay $140 for your first recharge and get 140GB on each of your first three recharges. This works out to around $23 a month for about 23GB of data. Plus, you'll get a $50 digital Visa gift card when you sign up to this plan via Finder.

Pros

  • You’ll get 20GB bonus data when you set up auto recharge.
  • Option to rollover unused data up to 200GB so it doesn’t go to waste.
  • Includes 3000 minutes of standard international calls to Zone 1 destinations, 400 minutes to Zone 2, plus 50 international texts.
  • Quickly sign up with an eSIM if you have a compatible handset.

Cons

  • The price will revert to $180 from the second recharge and the data allowance will drop to 90GB from the fourth recharge.
  • 4G and 5G download speeds are capped at 250Mbps, though this is fast enough for online activities on your phone such as streaming Netflix and online gaming.

Is a long-expiry prepaid plan worth it?

Long-expiry prepaid plans last between 90 and 365 days.

They’re well-suited for people who don’t mind paying upfront, know which network coverage works best for them and are fairly certain of how much data they need.

Here’s a quick pros and cons list if you’re still unsure:

Pros

  • Total yearly costs usually work out cheaper compared to a month-to-month plan.
  • You can set and forget about your mobile bills for up to a year.
  • Most plans let you use your data flexibly throughout the year - you can use less one month and more the next, and it'll balance out.

Cons

  • You need to pay the full amount upfront.
  • There's no option for a refund in case you're not happy with your service.
  • You'll need to recharge early if you aren't careful about your data use.

How do I find the best long-expiry prepaid plan?

Apart from the cost of the plan itself and your willingness to pay it upfront, you should consider some other key points before committing to a long-term plan:

Network

Figure out which network offers the best reception in your area before committing long-term. Telstra offers the widest coverage, and you're less likely to deal with reception issues than if you were to go with Optus or Vodafone. Plans on the Telstra network tend to cost a little more.

Consider expiry periods

Think about how long you're willing to commit to, whether that's for 90, 180 or 365 days. The longer you commit to it, the fewer times in the year you'll need to worry about recharging. Just keep in mind that if you choose to leave before your expiry period ends, you'll lose the money you paid upfront.

Data

Choose a data limit that matches your needs. Look at past bills or your account to see how much data you're currently using each month. When in doubt, add a some extra gigs on to how much data you think you'll use. You don't want to get stuck with not enough data after committing to a plan long term. Also keep in mind that some plans allocate monthly data limits. Reading the fine print before signing up!

Aaron McAllister's headshot

"I used to be lazy and just top up my phone each month. I then realised that the monthly cost for a 365 day plan worked out to be far cheaper and I wouldn't exceed the data limit. The savings was $16 per month less than what I was paying, which meant I was able to reduce my phone bill by $192 a year."

    I’m looking for a long term data only plan, preferably 5 years if possible. Data usage is low, just monitoring power at a site with no internet access.

      Hi Dean,

      Thank you for getting in touch with Finder.

      Currently, long expiry prepaid plans are up to 365 days which is for a year. Kindly contact your chosen provider if they may provide a modified mobile plan for your needs.

      I hope this helps.

      Thank you and have a wonderful day!

      Cheers,

    I intend to buy a prepaid mobile plan for 365 days. My present plan will end on 25/04/2019. Can I buy now and activate the SIM card nearer to the end date of my present plan?

      Hi John,

      Thank you for reaching out to Finder.

      There are SIM providers that may allow you to buy a SIM now and then activate on a later time. You may need to check this with the specific SIM provider whom you are considering to buy a prepaid SIM so you can be advised accordingly. This is normally applicable if you are to get a new mobile number. If you intend to port your number, you need to let the incoming provider know that you are planning to move your number and check their porting time frame so you can consider and check your options.

      Hope this helps.

      Kind Regards,
      Mai

    Hello, great article, but it seems as though none of the pre-paid plans listed allow calls to be received when roaming internationally? What prepaid long expiry plans allow you to receive calls internationally?

      Hi Aldimobile,

      Thank you for your enquiry.

      You can use any of the SIM cards featured on this page if you have an unlocked mobile phone, however, you can only use a Telstra SIM card on a Telstra locked phone. You can get in touch with Telstra for assistance in unlocking your Telstra locked phone.
