What are 365-day prepaid plans?
365-day prepaid plans (also known as long expiry plans) are a type of SIM-only mobile plan that lets you lock in a year of on-the-go coverage and connectivity in advance. You pay upfront, but once you've done that you're free to use all the data and other inclusions your 365 days SIM plan includes however you want.
The only catch is that if you use up your data faster than you expect, you may need to recharge and top it early. Otherwise, you've got an entire year from the moment you sign up for a brand new 365 day mobile plan to use it or lose it.
How to pick the best 365 day prepaid plan for your needs
Long expiry prepaid plans are, by their very nature, relatively straightforward and no-fuss. That simplicity is a big reason that people opt for them. Still, there's a few things to keep an eye out for when choosing a 365 day prepaid phone plan:
- Longer recharge durations: There are a few different types of long expiry prepaid options. The most common is the 365-day recharge, but there are also 90-day and 180-day options. Every now and then, telcos will off one-year recharge options, which won't necessarily last you 365 days, instead they expire on a year from the day you activate.
- Better dollars-to-data value: The easiest way to compare long expiry prepaid options is to calculate the equivalent monthly cost and inclusions. This allows you to compare 180-day and 365-day recharge options in a like-for-like way. For example, Kogan's $150 Small Flex Plan costs $150 and gets you 140GB of data to use over the year. That works out at roughly $12.50 and 11.6GB of data per month. You could then compare that against the Catch Mobile 365 day plan that comes with 200GB of yearly data, which works out to be $16.60 and 16.6GB of data per month.
- Data rollover: Different telcos offer different data rollover offers (some don't offer it at all). Some allow you to bank a limited amount of unused data for your next recharge, others let you rollover all of your unused data if you recharge before the expiry date. It's important to know which data rollover or data banking option is available to you before signing up.
- Auto-recharge with no excess data fees: Again, different telcos have different ways of handling excess data charges. Some will simply charge a per-megabyte rate for all data used in excess of your inclusions, deducting that amount from the dollar value of your recharge amount. Others offer convenient auto-recharge options that automatically top-up your balance via direct debit when you run out of credit or your plan expires
Expert Advice
"365-day long expiry plans can be a an excellent choice for mobile customers who use very little data each month and want to save by paying a bigger amount up front."

- Amaysim
- Catch Connect
- Boost Mobile
- Kogan Mobile
- Optus Mobile
- Coles Mobile
- Everyday Mobile
- Telstra Mobile
Is it cheaper to get a 365-day plan?
While 365 day and 1 year prepaid phone plans do command an expensive upfront cost, they can sometimes work out to be cheaper than their month-to-month counterparts. However, the downside of this affordability is that they tend to offer significantly less value from a dollars-per-gigabyte perspective. You're paying less, but you aren't getting as much for your money.
Are long expiry prepaid plans better value than monthly plans?
Long expiry, 365 day and 1 year prepaid phone plans are great for those who don't use that much data or like the idea of locking in the cost of their phone bill ahead of time. However, they aren't necessarily going to be the right for everyone as monthly SIM-only plans can offer significantly more data, perks and flexibility.
Is there a 365-day long expiry plan with unlimited data?
At the time of writing, there are no long expiry prepaid plans with unlimited data. If you do want excess-charge free or unmetered data, you'll have to go with a postpaid provider like Felix or Dodo.
Are there any 365 day mobile plans that don't expire?
No. Unfortunately, every prepaid mobile plan in Australia has some sort of timeline on when it will expire. If you're keen to put off having to think about your mobile plan for as long as possible, a 365-day long expiry plan like the ones featured on this page may be the best choice.
What happens if I don't use up all my prepaid data?
Typically, Aussies signed up for a long expiry prepaid mobile plan like the ones featured on this page lose any remaining or unused data once their expiry date arrives. However, some providers offer a form of data banking or data rollover. So long as you meet that (and any other) criteria, some amount of your data will carry over into your next recharge.
What is the cheapest 365 day plan?
If you're looking for the cheapest 365-day mobile plan, you're probably looking at spending around $100. However, that only applies if there's a good deal going. If there isn't, then you're looking at closer to $120.
Do you get access to all the data for a 365-day plan upfront?
Yes. Usually, prepaid plans give you all the data at the start of your plan's life rather than later on. The upside of this is that you can use the data how you want when you want. The downside is that you can get through your data allowance well before your expiry date arrives if you aren't careful. To help with that, some providers allow you to break your data out into neat monthly allotments.
How long does a long expiry prepaid plan last?
Long expiry prepaid plans vary in terms of how long they last. Shorter long expiry plans can last either 90 or 180 days while longer ones can last you a whole year.
Does Telstra have any 365-day prepaid plans?
Yes, Telstra offers some 12-month and 365-day long expiry prepaid phone plans. However, as usual, the provider behind Australia's biggest mobile network charges a premium. For that reason, it might make more sense of some to consider a Telstra MVNO like Everyday Mobile that offers 365-day plans instead.
Does Optus have any 365-day prepaid plans?
Yes, Optus offers some 12-month and 365-day prepaid phone plans. However, it's not always necessarily going to be the cheapest option when it comes to long expiry mobile plans. More often than not, you might be able to get better value from Optus MVNO providers like Catch.
Does Vodafone have any 365-day prepaid plans?
Unsurprisingly, Vodafone does offer a handful of 12-month and 365-day prepaid phone plans. Although there's definitely value to be had here, you might be able to save more money through an MVNO like Kogan Mobile so it can pay to shop around before you buy.
Does ALDI Mobile have any 365-day prepaid plans?
ALDI Mobile used to offer a $169 Mobile Plan with 365 day expiry. However, it has since discontinued that particular plan and has not replaced. At the time of writing, the number of ALDI Mobile (365 days expiry) mobile plans available in Australia is zero.
Does Amaysim Mobile have any 365-day prepaid plans?
Those in the market for an Amaysim 365 day plan currently have two options. The first is a $240 plan that comes with 4G Optus coverage, 200GB of data, unlimited data banking plus calls and texts within Australia. The second Amaysim 365 day plan is more expensive at $300 but only comes with an additional 40GB of data.
Does Lebara Mobile have any 365-day prepaid plans?
Looking for Lebara long term plans? The good news is that this particular provider has one of the biggest rosters of long expiry prepaid mobile plans in Australia, with prices starting at $160 for 120GB and going all the way up to $300 for 425GB.
Are there any Coles 365 day prepaid mobile plans?
Coles Mobile currently offers two 365 day mobile plans. The cheaper of these is priced at $195 and comes with 140GB of data. The more expensive alternative costs $240 and comes with 210GB of yearly mobile data.
