Why should I get a SIM-only plan?

SIM-only plans (or BYO phone plans) are great if you want to switch between plans easily, or don't want your monthly phone bill to include the price of a new phone handset.

You'll get all the bells and whistles you'd expect from a regular mobile plans such as data, calls and text messages, all through a small SIM card.

A SIM-only plan will also let you:

  • Use the phone you already have or buy one outright.
  • Switch to a cheaper provider when a new offer comes up.
  • Upgrade your phone whenever you want since you're not tied to a contract.

What type of SIM-only plan can I get?

If you've decided that getting a SIM-only plan is the best option for you, the next step is to choose between a prepaid and postpaid plan.

Getting on a prepaid or postpaid SIM-only plan will allow you to shop around and switch to a provider with better rates whenever you want.

These days, there's not too much difference in features between the two. The main difference is when you pay your bill.

Types of SIM-only plans

prepaid icon

Prepaid SIM-only plans

You can get 3 types of prepaid plans:

  1. Pay as you go. Top up credit when you need
  2. Month-to-month. Pay every 28 or 30 days
  3. Long expiry. Pay upfront for up to 12 months

Watch out for how much data you use before your next recharge. Once you run out, you won't have any more mobile data to use.

postpaid icon

Postpaid SIM-only plans

These plans:

  • Are paid for at the end of each month
  • Will almost always include unlimited calls and text messages within Australia

Watch out for additional excess usage costs. Unlike prepaid plans, you'll get charged for any data you use over your monthly allowance.

How do I find the right SIM-only plan?

You're likely after a SIM-only plan for 1 of 5 reasons:

  1. You want to lower the cost of your monthly bill.
  2. You can afford to buy a phone outright.
  3. Your contract is up and now you want a no-strings-attached phone plan until your next upgrade.
  4. You're after a no lock-in contract.
  5. You have a secondary phone that will suit a no-frills plan.

Keeping the above in mind, you'll need to consider a few things before hunting down the right SIM-only deal for you.

Think about:

  • What network you're after. You'll be choosing between the Optus, Telstra or Vodafone networks. Smaller providers, known as MVNOs, will often offer full coverage from any of the big telcos at cheaper prices.
  • Extra features you'd like with your plan. This can include data rollover, international calls, bill-shock protection and even discounts on your groceries.
  • How much data is right for your usage. Choose an amount that you will actually use in order to get the best value SIM-only plan for your money.


After that, it's as simple as filtering your results in our comparison table above to find the best deals for you.

What can I get on a SIM-only plan?

Popular features that come with a SIM-only plan include "unlimited data", data rollover, data-free streaming, bill-shock protection, and unlimited domestic calls and texts.

To learn more about each feature, just click on the headings below.

What's the cheapest SIM-only plan?

The cheapest SIM-only plans in our database are either PAYG plans or plans with short expiry periods.

  • Cheapest SIM-only plan overall: Optus Flex $1 per day
  • Cheap SIM-only month-to-month plan: TPG Mobile PAYG $1 per month

PAYG mobile plans are a type of prepaid mobile plan that come with a set amount of call and text credit and no data inclusions.

  • Good for: People who don't use their phones very much (1 to 5 days in a month) or anyone who needs a secondary SIM for their spare phone.

You can also get a short-term expiry plan that lasts between 1 to 7 days but again, these aren't helpful for daily usage and are geared towards travellers.

Instead, we recommend using the filters in our comparison table, setting the price to suit your budget and finding yourself the cheapest SIM-only plan for your needs.

  • Good to know: On average, Aussies are paying $56 a month for 40GB of data.

What's the best SIM-only plan?

There's no such thing as one size fits all when it comes to mobile plans. But arguably, the 3 big telcos offer better perks and features than their smaller counterparts.

In fact, 78% of Australians are with either Telstra, Vodafone or Optus, likely for this very reason.

Here's what you'll get for signing up with any of the 3 network giants.

Note: Prices and data inclusions were last updated June 2021. We've chosen to list the base prices of the plans below, with no promotional pricing showing.

What's the best mobile network in Australia?

No matter which plan you sign up to in Australia, it will be on 1 of the 3 networks: Telstra, Optus or Vodafone, even if the provider you're with isn't actually one of them.

Any provider other than the big 3 is known as a Mobile Virtual Network Operator (MVNO). These smaller providers will use either the Telstra, Optus or Vodafone network to provide their services.

SIM-only plans from smaller providers will often be priced cheaper in comparison because they don't have to pay to keep a network infrastructure up and running.

You'll usually get the same coverage as if you were with any of the 3 big telcos but with fewer plan features.

The only exception to this is Telstra, which only offers its full network coverage to 2 small providers, Boost Mobile and JB Hi-Fi.

  • Good to know: Almost 1 in 5 customers (18%) with the big 3 don't think they're getting good value for money. In comparison, just 7% of customers are unsatisfied with a smaller telco.

      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?

        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,
        Jeni

      I am looking for a best sim only plan for Sri lanka calls. Belong mobile was best, but not anymore as they removed Sri Lanka calls from their add-on since last week. I don’t need big data plan (happy with even 2GB). Please advice.

      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,
      May

      I cannot receive Optus bills as normal automatic email attachments. I have asked five different Optus shops to set it up for me and they all said that I would receive a link. Result – no link or anything else received.

        Hi Jeff,

        Thank you for reaching out to finder.

        You may log in to your online Optus account so you could opt in to receiving your bill via your email. If this does not work, calling the Optus customer support number would help so they could set it up directly for you. Hope this helps!

        Cheers,
        Reggie
