365-Day Prepaid Mobile Plans in Australia: Best Options Compared

Tired of paying for a mobile plan every single month? You’re not alone. Plenty of Australians are ditching the monthly billing cycle and switching to something far more convenient: 365 day prepaid mobile plans.

The idea is simple. You pay once, and you’re covered for an entire year. No more remembering to top up, no surprise charges, and no lock-in contracts to worry about. It’s a great option for people who want to keep things simple and budget-friendly.

But with so many providers out there, how do you know which plan actually gives you the best value? That’s exactly what we’re here to help you figure out. In this post, we’ll walk you through the best 365 day prepaid mobile plans available in Australia right now. We’ll break down what each plan offers, compare the key features like data, calls, and texts, and help you find the right fit for your needs. Whether you’re a light user or someone who needs plenty of data to get through the year, there’s likely a plan on this list that works for you.

What Is a 365-Day Prepaid Plan?

A 365-day prepaid plan is exactly what it sounds like: you pay once upfront and stay connected for a full year. No direct debits hitting your account every month, no reminders to recharge, and absolutely no lock-in contract tying you down. You choose your plan, make a single payment, and you are good to go for the next 12 months. It is a genuinely “set and forget” experience that simplifies your mobile life considerably.

To put that in perspective, a standard Australian prepaid plan runs on a 28-day cycle. That means you are looking at roughly 13 separate recharges every year, each one requiring you to remember, log in, and pay again. A 365-day plan collapses all of that into a single transaction. Less admin, less friction, and one less thing to think about throughout the year.

One thing worth knowing before you start browsing comparison sites: you will often see 365-day plans grouped under the broader label of “long expiry plans.” This category actually includes two types. There are 180-day plans (sometimes listed as 184-day or 186-day plans), which cover roughly six months, and then there are true 365-day plans covering a full year. Both sit under the same “long expiry” umbrella on platforms like WhistleOut and Finder, so it pays to double-check the actual expiry period before you buy.

A common misconception is that paying upfront for a full year creates some kind of contract obligation. It does not. These plans are fully prepaid, which means you are simply paying in advance for convenience. There is no credit check, no ongoing commitment, and no penalty for walking away. Paying annually is a choice you make for simplicity, not a binding agreement.

Finally, getting started is easier than ever. Both eSIM and physical SIM options are now widely available across providers offering 365-day plans, so whether you prefer instant digital activation or a traditional SIM card delivered to your door, you have options.

Who Should Consider a 365-Day Prepaid Plan?

Not everyone needs to recharge every month, and honestly, plenty of people shouldn’t have to. A 365-day prepaid plan is a genuinely better fit for certain types of phone users, so let’s break down who gets the most out of going annual.

The admin-avoider is probably the most relatable profile here. If you’ve been setting monthly reminders to top up your phone for years, you already know how tedious it gets. Switching to an annual plan means you handle it once, put it out of your mind, and move on. That’s it. One task replaces twelve, and your phone just keeps working without you having to think about it.

The budget planner will love the price certainty that comes with paying upfront. Mobile plan prices shift fairly frequently in Australia, but once you’ve locked in your annual rate, that price is set for the full year regardless of what happens in the market. No surprise charges, no fluctuating direct debits, and no mental energy spent monitoring for price hikes. You know exactly what your mobile costs for the year from day one.

Seniors and low-frequency users are a perfect match for this style of plan. There’s no app to log into every month, no direct debit to watch, and no stress about expiry dates creeping up. Set it up once and it simply works.

Parents managing multiple kids’ SIMs will immediately see the appeal. Instead of tracking 12 monthly recharges across two, three, or four lines, you make one annual payment per SIM and you’re done for the year.

Frequent travellers benefit in a really practical way too. Your Australian number and data stay active while you’re overseas, and if your device supports dual SIM or eSIM, you can pair your home plan with an EzySim World Travel eSIM for seamless overseas coverage without paying roaming fees.

International callers and multicultural households round out the list. A single annual plan with generous data and international calling inclusions bundled together is a much cleaner arrangement than juggling separate add-ons every month.

Top 365-Day Prepaid Plans in Australia Compared

So you’ve decided a 365-day prepaid plan makes sense for you. Now comes the real question: which one actually delivers the best value? Here’s a straightforward look at the main options available in Australia right now, so you can compare them side by side without the headache.

Heads up: Promotional prices change regularly, so always verify current pricing directly with each provider before you buy.

Breaking Down Each Option

EzySim runs on the Vodafone network and supports both physical SIM and eSIM, which means you can activate instantly without waiting for a card to arrive in the mail. Data rollover is available on eligible plans, so you’re not just losing whatever you don’t use. There are no lock-in contracts, which gives you genuine flexibility if your needs change. For Vodafone coverage areas (metro and most suburban locations), EzySim ticks a lot of boxes for everyday users who want simplicity and value without overcomplicating things.

Boost Mobile is currently running a sale at $305 (down from $365), giving you a massive 365GB for the year. That’s the biggest data bucket in this comparison by a significant margin. The catch is that it’s also the most expensive option, and this sale ends 31 August 2026, so standard pricing kicks back in after that. Boost runs on the Telstra network, which is widely regarded as Australia’s most extensive mobile network, especially outside major cities.

Lebara is offering a compelling promotional deal at $159 for 180GB (new customers only, ending approximately 7 September 2026), or $250 for 260GB on their standard plan. Both plans run on Vodafone with a 150Mbps 5G speed cap. The standout feature here is data banking; you can roll over up to 500GB of unused data on eligible plans, which is genuinely useful if your usage varies month to month.

Kogan Mobile comes in at $179.90 for 140GB, making it the most affordable confirmed entry point in this category. It runs on Vodafone’s 4G network, which suits most everyday tasks comfortably.

ALDI Mobile is worth checking directly, as they currently have a Double Data promotion running for new joiners (until 29 September 2026), plus data rollover on eligible plans.

Telstra vs Vodafone: Why It Matters

This is probably the most important decision factor that often gets overlooked. Boost uses the Telstra network, which offers broader coverage in regional and rural Australia. If you regularly travel outside major cities or live in a country area, that coverage difference could be a genuine dealbreaker. Vodafone-based providers like EzySim, Lebara, and Kogan are strong performers in metro and suburban areas, often at a friendlier price point. For city-based users, the Vodafone network is more than capable for daily use.

Also worth keeping in mind: those mid-2026 promotional prices from Boost and Lebara are time-sensitive. If you’re reading this after September 2026, mobile plan prices change fairly frequently so double-check the current figures before committing to any plan.

What Are You Really Paying Per Day?

Big upfront numbers can feel intimidating, but breaking them down into a daily cost changes everything. Let’s look at what you’re actually spending per day across the major 365-day plans currently available in Australia.

The standout figure here is Lebara’s promotional $159 plan for new customers. At roughly $0.44 per day, it’s currently the lowest daily cost in the comparison. To put that in perspective, you’d spend more than that on a single takeaway coffee, and yet this plan keeps you connected for an entire year. You can check the current 365-day prepaid options on Lebara’s website to confirm pricing and availability, as promotional rates do change.

Lebara’s $250 plan comes in at around $0.68 per day for 260GB, which is a solid middle-ground option if you need more data but still want a reasonable daily rate. Boost’s $305 sale plan works out to approximately $0.84 per day and delivers the most raw data at 365GB, with the added advantage of running on the Telstra 5G network.

For budget planners who find lump-sum prices stressful, this framing is genuinely useful. Instead of thinking “that’s $250 upfront,” think “that’s less than $0.70 a day.” Plus, a single 365-day plan replaces roughly 11 to 12 separate recharges you’d otherwise need to manage across the year, saving both money and admin hassle. You can compare prepaid mobile plans side by side on WhistleOut to see how these stack up against shorter-term alternatives.

What Happens to Unused Data When Your Plan Expires?

Here’s the straightforward truth about unused data: if your plan expires and you haven’t used everything in your allowance, that leftover data is gone. This is the default rule across pretty much all prepaid mobile plans in Australia. You don’t get a refund, and the GB don’t magically appear on your next plan. The only exception is when a provider specifically offers a rollover or data banking feature, and even then, there are conditions attached.

Some providers have made data banking a genuine selling point. On eligible plans, unused data can be banked and carried forward, provided you recharge before your current plan expires. Think of it like a savings account for your data. If your plan includes 20GB in a cycle and you only use 8GB, the leftover 12GB gets deposited into your data bank rather than disappearing. Over several cycles, that reserve can grow into a meaningful buffer for busier months, like when you’re travelling, streaming more, or just using your phone heavily. The key phrase here is “before expiry.” Miss that window, and the banked data is forfeited along with whatever was left in your active plan.

EzySim offers data rollover on eligible plans, which means light users aren’t simply leaving GB on the table each cycle. This makes EzySim genuinely competitive for anyone who doesn’t burn through their full data allowance every month.

This brings up a really practical point for light data users. A smaller plan with rollover can actually deliver more real-world value than a bigger plan without one, because every unused GB is preserved rather than wasted.

Always check the specific terms for any plan you’re considering, because rollover and data banking policies vary between providers and even between plan tiers within the same brand. Reading up on how unused data is handled by other users can also give you a realistic picture before you commit.

EzySim Annual Plans: What Is Included?

EzySim offers two dedicated annual plans: Plan Ultimate 12 and Plan Legend 12, both sitting under their Long Term Plan category. These are genuine 365-day prepaid plans, meaning you pay once and stay connected for the full year with no monthly recharges to worry about. To see the latest pricing, data inclusions, and a side-by-side breakdown of both options, head directly to the EzySim long-term plans page where everything is laid out clearly.

Both annual plans run on the Vodafone 4G/5G network, which gives you solid coverage across metro and regional Australia. You get the choice of a physical SIM or an eSIM, and there are no lock-in contracts, so you’re on prepaid terms the whole time. Data rollover is available on eligible plans, which means any unused data does not simply disappear if you recharge before your plan expires. That is a genuinely useful feature for anyone whose data usage varies month to month.

For multicultural households and frequent international callers, EzySim’s higher tiers include international calling benefits from the Beauty tier upward. If either the Ultimate 12 or Legend 12 plan falls into that category, you could be getting built-in international calling as part of your annual plan, rather than paying extra each time.

One standout perk worth highlighting is instant eSIM activation. Once you purchase your plan online, you can activate your eSIM immediately without waiting for a physical SIM card to arrive in the post. It is genuinely zero friction.

365-Day Prepaid vs Monthly Prepaid: Which Should You Choose?

The honest answer is that the best plan is the one that matches how you actually use your phone, not the one that looks cheapest at first glance.

Go with a 365-day plan if any of these sound like you:

• You use roughly the same amount of data every month and rarely feel the urge to switch things up
• You want to stop thinking about recharging altogether, set it once and forget it for a full year
• You are managing a phone for a child or elderly parent, where keeping the line active without monthly check-ins is genuinely valuable
• You are comfortable with a larger one-off payment and prefer the simplicity it brings

Stick with a monthly plan if:

• Your data needs shift around a lot, for example, heavier usage during school holidays, quieter months when you are mostly on Wi-Fi, or periods of travel
• You want to trial a new provider before committing to anything longer term
• You want to keep your upfront spend as low as possible, since very affordable monthly prepaid options do exist in the Australian market for price-conscious users

It is worth knowing that genuinely low-cost monthly plans are available for those who prioritise minimal upfront commitment over convenience. That is a completely valid choice.

Here is a simple rule of thumb to help you decide: if you have recharged at least six times in the past year without switching plans, a 365-day option will almost certainly save you time and very likely save you money too. Six unchanged recharges signals a stable usage pattern, and that is exactly the scenario where paying once upfront beats the ongoing monthly cycle every time.

Frequently Asked Questions About 365-Day Prepaid Plans

What is a 365-day prepaid plan?

A 365-day prepaid plan is a mobile plan where you pay once upfront and stay connected for a full 12 months. There are no lock-in contracts, no monthly billing cycles, and no automatic charges to your account. You simply recharge once a year and you’re done.

Are 365-day plans worth it?

For consistent users, absolutely yes. When you break the cost down to a daily rate, annual plans often work out cheaper than rolling over a monthly plan every four weeks. You also get the added bonus of price certainty; once you’ve paid, your rate is locked in for the full year regardless of any market changes.

Can I get a 365-day plan on eSIM?

Yes. EzySim supports eSIM activation on its annual plans, meaning you can set everything up digitally without waiting for a physical SIM to arrive in the mail. Several other providers in the Australian market also offer eSIM compatibility on long-expiry plans, so instant activation is very much achievable.

What network does EzySim use for its annual plans?

EzySim runs on the Vodafone network, giving you access to broad 4G and 5G coverage across Australia. It’s a solid foundation for everyday use, whether you’re in a major city or travelling regionally.

What happens to unused data when a plan expires?

This depends entirely on the provider. Some providers offer data rollover, allowing unused data to carry over when you recharge before expiry. Others don’t. Always check the plan’s Critical Information Summary before committing, especially if you’re a lighter data user who might not burn through the full allowance.

Is a 365-day prepaid plan a contract?

Not at all. Despite the annual payment structure, these plans are fully prepaid with zero lock-in obligations. You’re paying upfront for convenience, not signing away your freedom. If you want to switch providers after your year is up, nothing is stopping you.
