Expert picks

Every month, our team of experts dig through the hundred of plans available in our Mobile Plan Finder™ to find the best deals in the market. We find ones that we think are best suited for you across a number of categories. None of our picks are sponsored - we also take into account mobile providers and plans that we aren't partnered with - so that our winners for each category are chosen without bias.

We take these factors into account when choosing our winners:

  • Price per month (and whether promotional pricing is involved)
  • Data allowance
  • Plan length and contracts
  • Other notable features such as data banking, and international inclusions

Keep in mind: The plans we've chosen as the best might not always be the best one for you. We encourage you to compare your options and choose the one that best suits what you're looking for.

What makes the best mobile plan?

There isn’t a single answer to this, because it depends entirely on what you’re looking for and your personal mobile habits. With that in mind, here’s what to consider when narrowing down the right mobile plan for you:

  • Cost. This can go anywhere from $15 to over $100 a month, depending on what you get. For a prepaid plan, consider how frequently you’ll need to recharge. Figure out your maximum monthly mobile budget and remember the cheapest plans aren’t always the best due to very limited inclusions.
  • Data inclusions. Not just how much data you have, but whether you get free streaming, international roaming or data rollover between months.
  • Network and coverage. Telstra’s, Vodafone’s and Optus’ 3G/4G networks may have variable coverage over where you live, work and travel. Certain devices might enjoy faster speeds with some 4G networks like Telstra’s.
  • Excess data and charges. What happens when you go over your data limit? Some providers like Telstra or Vodafone may just lower your connection speed to 1.5Mbps, while others will charge you an extra $10 or so for additional GB blocks.

Should I get a prepaid or postpaid plan?

Is it better to buy a mobile outright or with a plan?

The first thing to know is that whether you buy your mobile upfront or on a plan, the actual cost you pay for the handset doesn’t change. The main difference is that you’ll be locked to a particular phone plan for the length of the contract and you’ll be paying the phone off over a period of time rather than all at once.

Generally, you’re better off buying the phone outright and picking a cost-efficient SIM only plan to go with it. However, if you can’t afford the handset outright or want the convenience of getting everything from a single provider, a contract could be the way to go. Just be aware that the plans available with handsets may not be the best mobile deal you can get.

Over 20% off for 12 months - pay $30 for 100GB of data per month. Plan reverts to $38 for 100GB per month after 12 months. T&Cs apply.

Which is better: an MVNO or the actual provider?

A mobile virtual network operator (MVNO) is a third-party retailer that offers mobile plans on Telstra’s, Vodafone’s or Optus’s networks, rather than owning or building its own infrastructure. The biggest difference between an MVNO and one of the big three carriers is usually cost, but you can see our guide on MVNOs to find out more.


  • Cheaper plans. Because MVNOs don’t have to pay to build and maintain network infrastructure, they usually have cheaper plans on offer than a provider like Telstra, which has more overheads.
  • Flexibility. Almost all MVNOs provide phone plans on a month-to-month basis rather than a multi-month contract, meaning you can switch plans easily to get the best value or as your needs change.


  • Reduced coverage. Most MVNOs use the wholesale network of a particular carrier, which offers slightly less coverage overall – usually only relevant in certain regional areas.
  • Limited handset options. Few MVNOs have handsets on contracts. If you want a new phone with your plan, you’ll likely have to go with a major carrier.
  • Fewer extras. Lower costs mean fewer features. You probably won’t get as many plan extras like free streaming from an MVNO compared to a more expensive major carrier plan.

Frequently asked questions

Can I bring my existing number to a new phone plan?

When switching to a new plan, you should almost always have the option to bring your old number with you at checkout. Always check with your new carrier first and do not cancel your current plan before buying a new one or you could lose your number. Read our guide on mobile number porting for more in-depth instructions.

What are data only SIM plans?

A data only SIM plan is a form of mobile broadband where you purchase a certain amount of GBs but don't get access to mobile network communication features. This means that if you insert a data only SIM into your phone, you won't be able to make calls or send texts, but you will be able to browse the Internet.However, a data only SIM can be inserted into any SIM-enabled device, including some laptops, tablets and other devices. You can also plug them into certain wireless modems, which can then be used as hotspots to provide network access. Learn more on our mobile broadband page.

What if I want to change phones/plans before my contract has ended?

If you want to change your plan but stay with the same provider, many will allow you to switch between a limited set of plans freely. But if you want to change your provider or phone entirely before the contract is up, you'll usually have to pay out the remaining value of the handset and maybe extra cancellation fees.This is why choosing the right contract length is important: a 36-month plan will give you lower monthly costs on your handset, but you should ask whether you'll want the latest model in the next couple of years or whether your phone will even last that long. 12- and 24-month plans have higher monthly repayments, but offer greater flexibility if you decide you want a change.

How do plans without excess data charges work?

Both Telstra and Vodafone offer a wide range of plans that claim no excess charges, unlike other plans which will automatically charge you for extra data blocks when you go over your limit. These excess-free plans function by allowing you access to more data for free, but at a severely reduced speed of 1.5Mbps, which will restrict your ability to do more data-intensive activity like streaming and downloads.

    Optus have offered, on a 24 month plan, a new iPhone 7 with unlimited text and national calls together with 10GB of data discounted to $45.20 per month. Is this a good deal?

    I would like to know which MVNO using full strength 4G network for voice and data. I heard that Boost is using Telstra’s full network and Virgin is using Optus. Is there any other MVNO using full strength network for both voice and data ??

      Hi Samy,

      Thanks for getting in touch with Finder.

      The network strength depends on different factors such as time and place. However, in terms of network coverage, the service an MVNO offers shouldn’t differ in any way at all from the service that you’d get from the underlying network provider at the same location. That makes sense because it’s the exact same network infrastructure. If there’s an outage or a reception problem with an MVNO, it’s a question of the underlying carrier’s network, not the MVNO.

      We also have a list of MVNOs along with the networks they use. Please check and see if it answers your question.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    I need a new mobile phone (keeping my existing mobile number) + prepaid monthly plan to receive incoming calls from work and reply back fast and easy … as my job based on how fast I receive the messages from work and can take the shift … so coverage is important … between Caboolture, the Sunshine Coast and Bribie Island . Best/lowest price deals with fast and safe/reliable network even in rain/storm? Any suggestions? Thanks*

      Hi Zita,

      Thanks for your inquiry.

      In terms of speed, calls, and messaging, all Australian telcos are largely using 3G networks. So we couldn’t single out who’s fast and who’s not. You may compare your phone plan using our comparison table and search filters to help narrow down your options. Please see the image below:

      Hope this helps.
