What is a SIM only plan?

SIM only plans cover your regular mobile talk, text and data needs, with no required handset repayments. These BYO phone plans come in every size and price range, meaning you can get something flexible that perfectly suits your needs, whatever they are.

Here are the main features of SIM only plans:

  • Come as a SIM card that can be inserted into your phone or other unlocked device
  • Don't come bundled with a phone, so you have to bring your own
  • Let you make calls, send texts and use data
  • Are mostly month to month (though contract plans do exist)

SIM only plans mostly come in prepaid or postpaid versions, explained in the next section.

What are the types of SIM only plans?

Even though there are two types of SIM only plans – prepaid and postpaid – they both come as a standalone SIM card, with the main difference being whether you pay at the start or end of the month.

These are the two types of SIM only plans available:

  • Prepaid plans: These let you pay for usage upfront at the start of the month. Your service is cut off when you hit your usage limit. Or you can opt to pay extra for a data top-up.
  • Postpaid plans: On these plans, you still have usage limits, but you can keep using your service after hitting them. If you do this though, excess usage charges will usually be added to your bill.

Postpaid plans used to be seen as better value, but this gap has shrunk over time. According to the ACCC's Communications Market Report for 2019–2020, postpaid plans offer a little more value for more expensive mobile plans, while prepaid services offer slightly more value for cheaper plans, with both having similar value in the middle.

How to compare SIM only plans

When comparing all the SIM only plans on the market, there are a couple of things that are important to consider to get the best plan for you.

  • Network. All providers use one of three networks: Telstra, Optus or Vodafone. They have varying levels of coverage, so pick one that covers you wherever you spend most of your time. For those in rural or regional areas of Australia, Telstra may be the only network available.
  • Extra features. This includes anything from bonus streaming data to international calls. Extras only add value if you're going to make use of them. Otherwise, don't be fooled into signing up for a plan with flashy extras that you're paying for but not even using.
  • Data per dollar value. The more data you need, the more your plan is going to cost. Make sure you're getting the data you need without blowing your budget. Keep an eye on data promotions though. Some SIM only plans offer bonus data for the first couple of months before dropping down by more than half the starting data limit.
  • Promotions. Many providers have promotional discounts which can save you money for the first few months of a plan. If you don't mind switching during the year to take advantage of deals, you can save a lot this way. Considering how easy it is to port your mobile number to another provider, this isn't a bad idea for value-conscious customers.

Is a SIM only plan right for me?

SIM only plans are a convenient and cheap option for many people. Here's why you might benefit from swapping to a SIM only plan:

  • You already have a phone that you like. SIM plans don't provide new handsets, so you'll need to have one of your own.
  • You don't want a contract. Whether you're waiting for a new phone release or you prefer flexibility, there are plenty of good monthly SIM only plans.
  • You use multiple handsets. These plans aren't network-locked, so switching phones is as easy as popping in your SIM.
  • Your data usage varies monthly. You can swap plans to get more data for a few months, then drop back down.

If you like the phone you currently have, SIM only plans are a cost-efficient choice.

Pros

  • BYO phone or use any one you like
  • Usually flexible, with no lock-in contract
  • Take advantage of new discounts
  • Choice of any network or provider

Cons

  • Don't come with a new handset

What can you get on a SIM only plan?

SIM only plans are as varied and numerous as the companies selling them, but there are a few things you might expect when browsing through SIM only plans:

Do SIM only plans come with a contract?

While there are plans that come with a contract – usually 12 months – make sure you're getting better value for your money before you sign up. Otherwise, it may not be worth it, since you're giving up the flexibility to switch to other plans that may suit you more.

With that in mind, here's how a Moose Mobile contract option compares to one of its similar monthly plans. Note that this is just one example from a particular mobile provider, so the savings might be more or less with other contract plans.

Plan nameMonthly costData allowanceTotal cost over 12 months
20GB 1 Month Plan$23.8020GB$285.60
20GB 12 Month Plan$2220GB$264

As you can see in the calculations above, signing up to a 12-month contract with Moose only saves you $21.60 a year. If you're usually the type to stick with the mobile plan you sign up for, this might be a little incentive for you to grab a contract since there is a bit of monetary savings involved.

But otherwise, think about whether saving around $20 a year is worth being forced to stay on one plan. Remember, this means if you decide you're not happy with the coverage you're getting and want to leave, you'll need to pay an exit fee if you're on a 12-month contract.

Other providers might not offer any dollar savings for signing up for a longer period, but instead give you more data. For example, Southern Phone's contract plans offer double or more data compared to its no-contract plans.

Can I get an unlimited data SIM only plan?

Yes, "unlimited" data mobile plans do exist, but there's a catch. Unlimited data mobile plans in Australia are marketed as plans with no excess data charges. Here's how most of them work:

  1. Full-speed data. Like most plans, you get a monthly data allowance. Your plan works normally until you've used up this full-speed data.
  2. "Unlimited" data starts. After you've run out of full-speed data, you'll still be able to send texts and make calls as usual, but you'll switch over to your "unlimited" data.
  3. Reduced download speeds. "Unlimited" data lasts until the next billing period, but it has a capped download speed. While a full-speed 4G connection averages around 50Mbps, "unlimited" data is restricted to somewhere between 1.5 and 25Mbps, depending on your mobile plan and provider.

Truly unlimited data at full speeds is yet to be introduced in Australia. So if you're after a SIM only plan that's as close to unlimited as there is, these plans with no excess data charges are as close as you'll get.

Alternatively, if you don't mind going the prepaid route, check out felix mobile. It offers an unlimited data subscription mobile plan, but is capped at 20Mbps from the get-go. Vodafone also has 1.5Mbps "unlimited" data on its prepaid mobile plans.

Which is the best SIM only mobile provider?

No singular provider can be crowned as the winner since it really depends on what you're after when you're looking for the best SIM only plan. That being said, we've looked into what the three major providers in Australia offer in terms of SIM only plans below.
Telstra logo

Telstra SIM only plans

Telstra is Australia's largest mobile provider, offering a huge range of SIM only plans.

  • Postpaid plans start at $55 per month, provide 1.5Mbps speed capped downloads after your monthly limit and potential 5G access.
  • Prepaid plans come with bonus data on the first three recharges and a data bank for unused gigabytes.
  • All plans give access to Telstra Air national Wi-Fi network and Telstra Plus rewards program.

Optus logo

Optus SIM only plans

Optus has become the cheapest of the big three providers (also including Telstra and Vodafone) and has its own growing 5G network.

  • Postpaid plans start at $39 per month, with 1.5Mbps speed capped downloads after your monthly limit. All come with potential 5G access.
  • Epic Data prepaid plans come with bonus data on the first three recharges, Optus Flex plans let you get small chunks of data with variable expiry dates and all regular expiry prepaid plans have data rollover.

Find out more about Optus mobile plans here.


Vodafone logo

Vodafone SIM only plans

Vodafone has changed its plans around a lot in the past few years, but still maintains a strong range of SIM only offerings.

  • Postpaid plans from $40 per month, with speeds capped at up to 25Mbps after your monthly limit.
  • Prepaid plans include bonus data on the first three recharges and data banking. Some come with 1.5Mbps speed capped "unlimited" data past your limit.

FAQs about SIM only plans

Will my phone work with any SIM only plan?

If you bought your phone outright, it should work with any SIM only plan. If you bought your phone on a contract, it may be network locked to that provider, forcing you to unlock your phone before buying a new SIM only plan.

Can I use my existing phone number on a new SIM only plan?

Absolutely. Australian consumer law guarantees that you can transfer your mobile number from one provider to another. This is known as porting your mobile number.

What happens if I go over my data limit on a SIM only plan?

Depending on your plan, there are two options. The first is that you'll be able to use data as normal, but be charged extra for your excess data usage on your next bill. The second outcome is that you'll be able to continue browsing, but your download speed may be capped at a low value, making browsing and downloading extremely slow. This all depends on which plan and provider you're with.

To avoid these outcomes, you can either use your provider's app to track your usage or get a plan with bill-shock protection to protect you from excess charges.

What SIM card size do I need?

SIM cards come in three sizes, with most providers these days selling "triple" SIMs that can be adjusted to whatever size your phone needs.

  • Standard (15x25mm). Previously the most common size for new phones, but hasn't been for quite a while. Usually only required in very old phones or extremely basic non-smartphones.
  • Micro (12x15mm). Introduced in 2003, you'll find micro SIMs accepted in some newer phones (2015-ish models), but still not super common these days.
  • Nano (8.8x12.3mm). The smallest and most common SIM card for modern smartphones.

Always check what size SIM your phone accepts before buying a mobile plan, to make sure that you can get the right one.

      I am interested in a sim only plan. I spent about 4 hours a day reading news and long form articles. Only reading, no videos or social media. How much GB will I need in a monthly plan?

      Thank you.

        Hi Michael,

        Thanks for your message. Reading online doesnt take too much data compared to video calling, watching, net calling, sending pictures. Reading on articles is as low a requirement as net browsing. Somewhere between 2GB or 4GB would suffice but this will ultimately depend on your usage. What you can do is subscribe for the lowest data arrangement and see how it will reach you in numbered days and increase as you go along.

        Hope this helps!

        Best,
        Nikki

      Does SIM apply to mobile phones & does a 4G SIM plan cover my 3G mobile?

        Avatarfinder Customer Care
        JeniAugust 14, 2019Staff

        Hi John,

        Thank you for getting in touch with Finder.

        Yes. You can use a 4G SIM card in a 3G enabled phone, but you can not use 4G in it. To use 4G, You require a 4G enabled handset along with a 4G SIM. This is due to the reason that 3G phones work on WCDMA technology, which is different from LTE technology used for 4G connections.

        I hope this helps.

        Thank you and have a wonderful day!

        Cheers,

      Hi Sanjay,

      Thanks for reaching out.

      You may refer to our list of cheap mobile plans with international calling (including India). Local calls are usually unlimited, but for international calls, number minutes are generally capped. You can find that information in the description of the plans listed on the page. Once you’ve chosen your plan, you can go directly to the provider’s page and apply from there.

      Hope this has helped.

      Cheers,
