Is a long expiry plan right for me?

Long expiry prepaid plans last between 90 to 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.
  • No need to worry about paying for recharges to top up your plan or paying monthly phone bills.
  • Most plans let you use your data freely throughout the year so you can use less one month and more on another, and it'll even out.

Cons

  • You'll usually need to pay a decent amount of money upfront ($100+).
  • There's no option of 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 usage.

How do I find the best long expiry 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 expiry plan:

mobile network signal
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.

  
Plan length
Consider expiry periods

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

  
phone with arrows pointing to opposite direction
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!

"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."

    Hi, the family is on an Optus legacy family plan with discounts. My daughter is going to Canada for two years but doesn’t want to lose her number. Is her best option to port her number over to a pay-as-you go plan with Aldi/Amaysin ($2/$15) until she returns? Or is there a beeter option? Thanks

      Sarah Megginson's headshotFinder
      SarahDecember 2, 2025Finder

      Hi Peter,

      Yes, you’re on the right track! The simplest and cheapest way for your daughter to keep her Australian number while she’s in Canada for two years is to port it from your Optus family plan to a low-cost prepaid or PAYG service like ALDI Mobile or amaysim. These plans let her “park” the number and only need a small recharge every 6–12 months to stay active, which is far cheaper than keeping it on a full postpaid plan. The only thing to check is whether she needs overseas SMS, as most prepaid services allow receiving SMS overseas, but it’s worth confirming. Hope this helps!

    Hi. I used generally 80 GB per 365 days. My current plan of 240 GB expires in 2 weeks and I have 174 GB left! I cannot find a plan with low data. 80 to 100gb will suit me. What do you recommend? Michel

      Hi Michel,

      Depending on your budget, there are a range of plans that might suit your needs. The Kogan Small 365 Days Flex plan is 140GB for $179.95, but until November 13, they are offering a special rate of $159 on the Kogan Medium 365 Days Flex plan, which comes with 200GB. You can view these offers and more on this page. Best of luck!

    I am an older lady with not a lot of understanding re my mobile phone. I am with Optus pre paid. But it keeps running out of money. I usually pay $30 at a time. It doesn’t seem to last out the month. I rarely use my phone. It’s more for an emergency, when I’m away from home, as I can’t get coverage at home. Which plan would suit me best?
