Our comparison tool is free to use — simply compare plans from a range of providers and go.
Using our comparison tool and guides, you have the information you need to find the right plan for you.
When choosing a SIM-only phone plan, you’ll need to have an idea of what you want from your plan, and what your budget is. However, it’s important to be realistic about your budget and plan needs. After all, as nice as a $10 per month plan is, if you need 20GB of data, you’ll need to increase your budget.
It’s also important to compare plans from a range of providers in order to find a plan that will most meet your needs. You can use our comparison tool at the top of this page to help you compare plans from a range of Aussie telcos. Using our comparison tool is free and easy, and allows you to filter results by price, data inclusions, network provider and more, to help you find and compare the best SIM-only plans for you.
There are two types of SIM-only plans – prepaid and postpaid. But what exactly are the differences, and how do they work?
Prepaid SIM plans allow you to pay for your talk, text, and data inclusions in advance. Most prepaid plans are priced at a set amount for each renewal, and include unlimited standard calls and messages, along with a data allowance. This can also take the form of ‘pay as you go’ plans (like traditional prepaid plans) where your call/SMS/data usage is taken from your pre-loaded credit.
You’ll receive a set length of time — known as an expiry period — in which to use these plan allowances, after which your plan will reset. Expiry periods can be from as short as seven days, or as long as a year. However, the standard length for most prepaid plans is 28 or 30 days. You may then need to manually ‘recharge’ your service by purchasing more credit or plan inclusions, but many providers now offer an auto-recharge option that instantly renews your plan after each expiry period ends.
If you’re on a postpaid phone plan, you’ll receive a bill for your mobile use once a month (when you receive the bill will differ between telcos), which will include your standard plan price, plus any additional charges you may have incurred during your billing period.
Most postpaid plans offer unlimited standard talk and text, plus a monthly data allowance. However, you may be charged extra for items such as excess data use, international roaming or non-standard calls.
Postpaid plans are generally billed on a monthly cycle, and tend to be contract-free, although 12-month and 24-month plans are available. These plans are more or less identical to those offered with a new smartphone, but allow you to bring your own phone instead.
If you’re looking at buying a new phone and considering whether it would be cheaper to buy it outright and bundle with a SIM-only plan or to buy your device on a plan.
While some phones are only available to buy outright, others might be available to bundle on a plan from some telcos. Buying a phone outright compared to on a plan isn’t always the cheapest way to pick up your phone. You can read our guide on buying a phone outright vs plan, to help you find which option will be better for you.
A SIM-only plan requires just one thing — a SIM card. This little piece of technology contains a chip that allows a device — such as a smartphone or tablet — to connect to a mobile network. In addition to physical SIM cards, some telcos also offer the option of an eSIM, which requires an eSIM-compatible phone to work.
The type of phone you have will determine which size SIM card you need. There are three types of SIM cards that can be used — Standard, Micro and Nano. A Nano SIM is the smallest size of SIM card, and the most common SIM card type you’ll need for newer smartphones.
If you’re not sure which SIM card you need, either look at the SIM card tray in your phone, or look up your phone’s model and SIM card size. Most telcos offer 3-in-1 SIM cards, so you’ll be able to snap out the size that you need for your specific smartphone and then take the steps to activate your new SIM card.
Choosing a great value SIM-only plan does greatly depend on what you’re looking for in a SIM-only plan as the best SIM-only plan for one person might be different for another. At Canstar Blue, our Value Rank helps to determine which plans have overall great value for money; however, what is great value to one person, might not be the same value to another person.
When comparing SIM-only plans, you’ll need to consider your budget (a realistic idea of how much you’re willing to spend on a plan) along with how much data you need. By comparing plans with your data needs and budget in mind, you can find options that suit your needs — and from there you can determine which plan is going to offer you the best value for money.
At Canstar Blue, each year we release our Customer Satisfaction ratings for SIM-only phone plans across both prepaid and postpaid plan types.

Best Rated Postpaid Phone Plans
Telstra owns and operates Australia’s largest mobile network with both 4G and 5G coverage. Telstra offers a wide range of SIM-only phone plans including prepaid and postpaid, along with plans bundled with a new phone.
A range of telcos use the Telstra 4G and 5G network to deliver prepaid and postpaid plans to customers. These MVNOs include:
Australia’s second largest mobile network is Optus, with 4G coverage available to 98.5% of the population and 5G rolling out in selected areas, excluding NT. Optus offers a wide range of SIM-only phone plans including plans with a new phone and prepaid and postpaid plans.
There’s a wide range of telcos offering phone plans on the Optus 4G and 5G network. Some of these MVNOs are:
Vodafone is Australia’s third largest telco, with the smallest network of the three, however it still covers a wide range of the population. Like its competitors, Vodafone offers a range of SIM-only prepaid and postpaid plans, plus plans bundled with a new phone.
Several smaller telcos offer phone plans on the Vodafone 4G and 5G network. Here are some of the MVNOs offering Vodafone coverage:
If you’re planning to use your phone overseas, you may find it easier and cheaper to replace your normal SIM card with a travel or international SIM. You’ll generally want to buy a travel SIM card before you head overseas, and they can often be used across multiple countries.
Another option is to buy an international SIMs card, which offers service in one country or region outside Australia, and can be bought after you’ve landed at your destination.
As SIM-only plans are the most common type of phone plan available in Australia, you’ll easily find a plan to suit your needs. Most SIM-only plans include unlimited standard national calls and SMS as default, with data inclusions varying between plans and providers.
Generally, the more expensive a plan is, the more data will be included on that plan. Which means its important to understand how much data you think you will be using day-to-day. Some telcos might also offer extras (free streaming subscriptions, rewards points, etc) on plans beyond that simple call, SMS and data inclusion. You can also find SIM-only plans with unlimited data, however this might sometimes have a catch where your unlimited data is at a capped speed.
There are SIM-only plans to suit all sorts of phone users, from cheaper plans suited to kids, seniors and low-phone users, to plans with huge data inclusions. No matter your needs or budget, it’s likely you’ll find the best SIM-only plan to suit you.
