Now that OVO is no more, Dodo has taken the top spot as the best value data SIM, if you don't mind signing up for 12 months, that is. If you do very much mind, the Optus $30 Prepaid Starter Kit is your next best bet for a short-term deal.

This month, OVO's Mobile Broadband plan still holds the title for best value. But if the Optus network doesn't cut the mustard, Telstra's 200GB mobile broadband plan isn't far behind on value.

An iPad without an internet connection is like a car without fuel. Even if you think you’ll use your iPad in a place where you get WiFi, having a SIM card installed means you can get online anywhere and at any time.

Most people these days have an unlimited NBN plan at home, but SIM plans are great for those who rely on their iPad (or other tablets) on their daily commute. While there are no option for unlimited mobile data plans, there are a few that come close.

With these high data-usage plans, you’ll be able to connect your iPad or tablet to the internet whenever you need to. And if you invest in a portable WiFi dongle, you’ll be able to share that data around, becoming the most popular person in your study group.

Before we get started, let’s take a look at the most popular data SIM plans this week. This list is updated daily, so you can be sure the latest deals appear in this table below. The rest of our editorial recommendations are updated periodically.

Best Data-only SIM overall

Dodo’s 25GB Data SIM plan doesn’t have the best data-per-dollar value on the market, as most mobile and internet matters, you only find true value at the pricier end of the spectrum. Our best value pick is a plan that comes at an affordable price with ample data, and 25GB should be plenty if you’re only planning on using it outside of the home. If you are looking for an NBN alternative to cover you at home, you probably want to consider a Home Wireless Broadband plan.

At $20 per month, for 25GB of monthly data on the Optus 4G network, Dodo’s plan is a steal. The only downside is you’re contracted for 12 months. If you’re not looking for that kind of commitment, take a look at these popular month-to-month Data SIM plans.

Best Optus data-only SIM

If you’re looking for a short-term solution on Optus, you should consider taking advantage of the provider’s $30 Data SIM Starter Kit. For your first $30 recharges (every 30 days), Optus will give you 50GB of data. It’s important to note that the 50GB of data is made up of 35GB of bonus data, and 15GB of regular data. After your first three recharges on Optus prepaid, your data will revert to 15GB per recharge, which is a far less tempting deal.

If you’re looking for a longer-term mobile broadband solution on Optus 4G , take a look at the most popular Data SIM plans on the network.

Best Telstra data-only SIM

Telstra plans aren’t usually the cheapest options, but the network is arguably the fastest for mobile data, and you might find the coverage is better if you travel outside of metro areas for work or holidays.

The $75 Large Data Plan gives you 200GB per month. While this mobile internet plan is great value and month-to-month, if you require a 4G or 5G compatible modem, you’ll need to pay an additional $4 per month for device repayments over a 24-month contract or opt for the 36-month option.

There aren’t any excess data charges, however, if you go over your data limit, your mobile broadband speed will be capped at 1.5Mbps and may be even slower during peak hours. You’ll also have access to data-free sports streaming of content including AFL, AFLW and NRL at no extra cost, plus data-free Apple Music music streaming (you’ll need to get a separate Apple Music subscription though).

If paying $75 every month is not affordable for you, it’s worthwhile considering other plans on the Telstra network. Here are this week’s most popular Data SIM plans on the Telstra network.

Most popular Data SIM plans

Vodafone’s 100GB Data SIM plan will currently give you an additional 50GB per month, totalling 150GB of monthly data for $60 per month. That’s a decent deal at the best of times, but it’s even better until 14 September 2020, when the deal expires. Vodafone’s Mobile Broadband Plan offers a 30-day network satisfaction guarantee, and further discounts if you bundle multiple services (like Vodafone mobile and NBN).

It’s consistently the most popular Data SIM plan in our engine. The one plan that bests it is Spintel’s 500GB mobile broadband plan, which is a great deal, but it requires a mobile broadband modem and can’t be used in a tablet.

Can I get a data-only SIM with unlimited mobile data?

The short answer is: no. To date, no service provider has offered unlimited data mobile plans, and even though Telstra and Vodafone now offer phone plans that slow down your connection when you reach your data limits (rather than charging you extra) these plan features haven’t yet trickled down to mobile broadband plans.

Once again, Vodafone’s limited-time 150GB deal is a tempting offer, but for our high-usage pick, Telstra’s $75 Large Data Plan takes the cake. It gets you 200GB per month, on Telstra’s market-leading network, as well as data-free Apple Music and sports (AFLW, AFL, NRL, A-League, and Netball), all with no lock-in contract.

If Telstra’s not your telco of choice, take a look at the plans below. These are the Data SIM plans with the most data in our engine.

How we chose the best data SIM plans

There are dozens of service providers offering data-only SIM plans these days, which can make it difficult to compare plans and find a bargain. The providers tend to make their plans slightly different to gain a competitive advantage, but this means we usually need to crack out the calculator to find the best data-only SIM plans.

We start by assessing a few different use cases and then setting criteria around how much data you will need and which standard plan terms, like contract length, are the most meaningful. We then dig into the nitty-gritty of the offer. Data saving features like data free media streaming score well because of how these will extend the time you can spend online each month.

For prepaid plans, we keep an eye on the number of days before your credit expires. The difference between 28 day expiry and a monthly plan works out as being a whole extra month you need to pay for each year – from 12 recharges to 13 recharges. Again, our calculators are useful here to figure out the total cost you’ll pay over a year, rather than simply comparing the monthly fee.

Which modems and devices are best for data-only SIM plans?

Businessman using tablet

As the name suggests, a data-only SIM plan is sold without a device. When you buy it you’re given a SIM card in a small cardboard package. You’ll need to bring your own device to put this SIM card to work.

iPads and other tablets

An Apple iPad with a SIM card slot is a common example of the sort of device you might use. But you need to make sure you have the right iPad, as Apple sells a cheaper model without the SIM card slot you need. The same goes for Samsung tablets and Microsoft Surface Pro laptops. There are 4G versions available, but you need to double-check that you are buying the model with this feature as it can be easy to miss.

An old smartphone

This option is often overlooked, but if you have an old smartphone gathering dust in a drawer you can use it as a modem by switching on the Personal Hotspot mode in the phone’s settings. All iPhones and Android phones of up to five years old or so will have this feature available. However, some providers (*cough* Telstra) block the use of data-only SIMs in smartphones. It will work for a majority of provider SIMs, but it is a question worth asking before you sign on.

Portable WiFi hotspot or dongle

Lastly, there’s the trusty portable WiFi hotspot. The student and commuter’s best friend, a portable WiFi modem allows you to connect multiple devices (laptop, smartphone, tablet, etc.) without the need to hotspot.

Tethering is a good solution to share your data with the gear you’ve got, but a personal WiFi dongle is a much more convenient solution.

Here are a few providers that bundle portable WiFi dongles with their mobile broadband plans.

What is the cheapest mobile broadband plan?

We currently have over 30 internet providers in our database right now, and compare just under 50 different data-only SIM plans. Below are the top 5 cheapest options in our comparison engine.

Some of these plans are exceptionally cheap, but make sure you get an eye out for one-month promotions and credit expiry of a week or less.

Now that you know, here are your next steps.
