A snapshot of prepaid SIM plans
A prepaid mobile plan lets you:
- Choose your plan based on data, price or length
- Pay upfront so there are no surprises
- Recharge online when it expires
- Switch providers if you like
You’ll only pay extra charges if you add features such as an international roaming pack.
What’s the alternative to prepaid mobile plans?
The other common phone plan type is a postpaid plan, where you’ll pay after all your usage is added up. You can learn about postpaid plans here. If you’re after more certainty with your phone budget, you could stick to a prepaid plan.
The basics of prepaid plans
You need a phone plan to make calls, send texts and use the internet on your phone. Prepaid mobile plans keep it very simple by charging the cost upfront, which means you can’t overspend unless you opt for more inclusions.
Prepaid SIM plans are a great option if you:
- Love saving money
- Like to control your budget
- Need a plan for a teen or new phone owner
- Run a business and need to manage employee use
When you buy a prepaid SIM plan, you can choose the data limit (more on that in a moment) and the length of time your plan goes for. Here are the most common expiry lengths:
Month-to-month (28 or 30 days)
Lots of people use month-to-month plans because they can switch frequently to nab discounts or if they’re unhappy with the service.
✔ You’ll typically get data, unlimited calls and texts and the option to add other inclusions.
❌If you run out of data, you’ll need to recharge your plan early.
Long expiry (90 to 365 days)
Plans with a long expiry period often work out the cheapest overall, but you’ll need to fork out the entire cost upfront.
✔ Set and forget your phone plan for months.
❌ Can’t take advantage of other plan discounts in the meantime.
Pay As You Go (PAYG)
PAYG plans typically suit people who don’t use their phones much, like seniors or younger kids. You pay a set amount upfront and use it up like a bar tab when you make calls, send texts or use the internet.
✔ Much cheaper than a plan for people who don’t use their phones much.
❌ Far more expensive for regular phone users (and not recommended).
The most important factor in choosing a prepaid SIM plan
Data. It’s the most important factor besides price.
You see, when you buy prepaid plan, you have to assume the amount of data you’ll use. If you run out, you have to recharge your plan early, which sucks. You’re not getting great value from your plan.
So, let’s get into the weeds for a moment and calculate how much data you need.
If you’ve used a phone plan before, you can look at your average monthly data usage. Use that figure as a starting point for your prepaid mobile plan.
But, suppose it’s your first phone plan or your circumstances have changed. In that case, you can use this as a guide:
Typical internet use | Data needed per month |
Email, general browsing and some social media | 3GB – 7GB |
All of the above plus: Music streaming, some online gaming and streaming YouTube | 7GB – 15GB |
All of the above plus: Streaming TV, downloading games and movies | 15B – 20GB |
💡 If you’re still not sure, that’s ok. Prepaid SIM plans let you switch your data amount when you recharge. So, guess the amount for now and slide the data amount up or down each month until you find the sweet spot.
How do recharges work with prepaid SIM plans?
Also called a renewal or ‘top up’, recharging keeps your current plan going without missing a beat (or a single second on TikTok). Most plans have auto-recharge turned on as a default setting, which you can switch off via the app.
If you turn off the auto-renew function, just remember to set a reminder on your phone to renew or change your plan before it expires.
⚠ If you use your data up before the expiry date, your plan may auto-renew without you noticing. Constantly recharging your plan early will cost far more than adding more data, so keep an eye on your usage and change your plan accordingly.
Choosing a good prepaid SIM plan provider
Most phone plan providers have prepaid options. Bigger names like Optus, Telstra and Vodafone may have more impressive data packages and features, but they’re often more expensive than the smaller brands.
Smaller brands don’t have a physical phone network to upkeep, expand and improve. Instead, they borrow from the big names and pass the savings on to customers. Don’t be afraid to look at smaller companies! Some, like Boost, are even owned by one of the big telcos, so you’ll get the perks of a big network with the price of a smaller brand.

Choosing your prepaid mobile plan features
Almost all plans include unlimited calls and texts. These are other features you can look for to help you decide on a plan.
Data rollover. Check if the plan has a rollover feature or data banking that carries your unused data over when you recharge. Some plans also have an option to ‘gift’ your data to someone else.
Network coverage. Most Aussies don’t need to worry about coverage since the main 3 telcos cover between 96% and 98.8% of the population. But, if you live rurally, you might want to look at the plan provider’s coverage map first. Telstra has the greatest coverage, followed by Optus and Vodafone. Smaller brands also use one of these 3 networks.
Expiry date. Prepaid mobile plans have expiry dates anywhere between 28 and 365 days. Typically, the longer the plan the greater the discount, but remember you’ll pay the full amount upfront and won’t be able to get a refund. And, if the plan is 28 days you’ll likely have to recharge 13 times per year rather than 12 (yes, it’s a bit of a sneaky ploy).
eSIMs. Not all plans have eSIM compatibility yet, but it’s the way the market is going. eSIMs can be instantly ‘downloaded’ and activated on your phone without any physical card needed. Most new smartphones are eSIM-ready.
Extras. Some plans may include extras such as limited international calls and texts, Wi-Fi calling capabilities and endless data. It’s common for brands to offer big discounts and bonus data to entice you over.
