Unlimited data SIM only plans

Both Telstra and Vodafone's SIM only plans have "unlimited" data, plus a certain amount of "full speed" data. The catch is that once you exceed that "full speed" data limit, you'll have your connection throttled.

With Telstra, it's reduced to 1.5Mbps on every plan. With Vodafone, the speed cap ranges from 2Mbps to 25Mbps depending on which plan you've bought.

So for example, if you use 60GB in a month on a 40GB Telstra unlimited data plan, you'll get the first 40GB at your full download speed, while the next 20GB will be reduced to a maximum of 1.5Mbps.

What do 1.5Mbps speeds look like?

A regular 4G connection in Australia has an average speed of around 38Mbps and a maximum speed of 150Mbps. Since 1.5Mbps is about 4% of that average speed, you'll certainly notice a difference in browsing and streaming.

Netflix, for example, lists 1.5Mbps as the absolute minimum speed for watching anything at all, though it's unlikely to be particularly crisp. You need a stable 3Mbps to watch a video in decent SD quality.

Which network is best for unlimited data?

If you're looking for an unlimited mobile data plan, you'll most likely be choosing between Telstra and Vodafone. Each offers slightly different benefits, so the best choice will depend on what you're looking for. Here's how their unlimited plans compare:

Vodafone Telstra
Monthly plan prices $40-$120 $55-$115
Full speed data 10GB-150GB 40GB-180GB
Lock-in contracts
Phone available with the plans
Data-free media streaming
International inclusions
Rewards program

For a more in-depth look at the extra inclusions from Telstra and Vodafone, check out our comparative lists below:

Telstra's extra features

  • 5G access. On Medium or larger plans, for customers with an eligible device in serviced areas.
  • Telstra Air WiFi. You gain access to over 1 million free Wi-Fi hotspots across Australia on any Telstra plan.
  • Free sports streaming. No data use when you stream certain sports like AFL, NRL and others.
  • Free music streaming. No data use when listening to Apple Music, but you need your own subscription.

Vodafone's extra features

  • Discounts on bundled plans. Putting your plans together on the same account can make you eligible for discounts.
  • International minutes. All but the cheapest plan offer minutes for calling or texting various countries around the world.
  • Network satisfaction guarantee. Drop your plan with no penalty if you aren't happy with Vodafone in the first 30 days of service.
  • $5 roaming. You can get some international roaming packs for $5 a month.

Both Vodafone and Telstra offer unlimited plans with handsets, so you can pick up a new phone with one if you need it.

While neither provider is outright better, Vodafone's more expensive plans offer unlimited data at a much higher potential speed than the 1.5Mbps from Telstra. However, Telstra has more bonus features for customers who will use them, and Vodafone's extra unlimited speed only applies once you've run through your full speed data.

The table below shows unlimited data plans with a phone from Telstra and Vodafone. The iPhone 11 64GB is selected by default, but you can hit "filter results" to add any other handset you might be after with the +add more button, such as the Samsung Galaxy S20.

What about Optus unlimited mobile data?

The unlimited mobile data options with Optus don't work the same way as with Telstra and Vodafone. With Telstra and Vodafone, there are specific plans to sign up to if you're after unlimited data, but Optus's options are available on nearly all its mobile plans.

Optus's "Unlimited Data Day" add-on is available for postpaid customers on Optus Choice, Optus One, Optus Family and Optus Kids plans, plus Prepaid Epic Data customers paying $30 or more for recharges. You pay $5 and get 24 hours of unlimited, full speed data, before returning to your regular plan inclusions.

It can be added through the My Optus app. There's no limit as to how many unlimited add-ons you purchase, so you could buy one every day if you wanted to – just be careful because the prices will stack up!

Do you actually need unlimited data?

The prospect of unlimited data may be tempting, but consider how much data you actually use – it's probably less than you think. You can check your usage via your phone, your last monthly phone bill, or you can make an estimate with our data usage calculator.

While unlimited mobile data sounds like a great idea, think about whether you actually need it while you're out and about on your phone. Here are a couple of things to consider:

Boy asking a question in a speech bubble
What do you actually use your mobile data for?

Most things you do on your phone only use a small amount of data – the only activities that really chew through it are high quality video streaming and big file downloads.

Two sliders showing fast and slow speeds
Unlimited data isn't necessarily at full speed

Even if video streaming on mobile data is a hobby of yours, unlimited data won't really help if it's not downloading at full speed.

Mobile apps using mobile data
How much data do you really need?

Even for huge data guzzlers, there are cheaper big data plans on offer.

Whether you need unlimited mobile data or not obviously depends on what you're planning to use it for. If you use your mobile data at home instead of using a fixed-line Internet connection, these unlimited mobile data plans could be a great way to avoid accidentally going over your data limit.

But if price is a factor for you, you could be better off getting a data-capped plan that suits your usage habits at a lower monthly cost.

Take a look at these big data mobile plans

If you're looking for a mobile plan with decent data but not unlimited, we've put a few below that offer 40GB and above.

Otherwise, your best bet is to look for plans with unlimited streaming options on services like Apple Music, Spotify, or bonus data offers for video streaming on platforms like Apple TV or Netflix. These will preserve your data when you're streaming certain types of media. Most of the time you'll need an existing subscription to the service to take advantage of the offer.

FAQ about unlimited mobile data

Is unlimited data really unlimited?

Yes, technically, since you can keep using your mobile data even after the specified data limits on eligible plans. These data allowances are instead a guideline on how much data you will receive at full speeds. Anything used past your "full speed" data will be limited to a slower speed.

Does Telstra have unlimited data?

Yes, Telstra's 4 regular SIM only plans come with unlimited data, which are marketed as "endless data" mobile plans. However, they also have a "full speed" data allowance. Once you've gone past that limit, your connection will be slowed to 1.5Mbps, though you won't be charged for excess. Telstra's plans start from $55 per month.

Do I need Wi-Fi if I have unlimited data?

The answer is probably yes. In most cases, the speed you'll receive after going over your data limit will be slower than your normal speed so you won't be able to do as much as you want, as quickly as you want. In comparison, the slowest fixed-line NBN connection has an average speed of 10Mbps, more than 6 times Telstra's 1.5Mbps speeds.

If you're looking to buy a mobile phone plan with full speed unlimited data, your best option would be Optus's data add-on, but it's not exactly the most cost-effective solution.

Instead, consider whether you need to make calls and texts on the unlimited mobile data plan you're looking to get. If you're just looking for a large chunk of full speed data, you could save a lot of money by investing in a mobile broadband or home wireless plan, instead. Both these options still use mobile networks to connect you to the Internet (just like your mobile plan).

Just keep in mind that currently only home wireless broadband plans come with unlimited data, but they're not exactly the most portable solution.

    Three.ie unlimited data and no throttling. While calls and texts are limited depending on plan, everyone uses data to communicate.

      Ok Sorry but the reaaoning given by the 3 telcos is a load of nonsense. A modern city like HK with a third the population of Australia ALWAYS has unlimited data and plenty of call time in all their plans. There is NO difficult decision to make or justifiable reason why the telcos here can t offer unlimited data. The ONLY reason is pure GREED. Comparing the situation to the very scattered and poorly serviced US network smacks of a cover up. Your writers can do better than that.

      Hello Nick,

      Thank you for your inquiry.

      We appreciate your sharing on this matter. Indeed many Australians are looking forward for that day when we can use unlimited data on our mobile phone plans. Just to clarify some points though, it is not only US that uses “capping” on their unlimited offers. Many providers, including the ones in Australia, are doing that in compliance with Fair Usage Policy (FUP), that will ensure equal distribution of network resources to all customers.

      While no signs can be seen yet if Australian providers will give this, your options will be to use home/office wifi, use public wifi, if you’re a Telstra fixed broadband customer you can use Telstra Air, pre-load your content if you’re watching videos, or use mobile broadband device.

      Hope this helps.

      Cheers,
      Jonathan

    What about Vivid Wireless?
    They have an Unlimited Internet Plan for $89 per month.
    Vividwireless LTE internet service provides up to 10mbps download and 1 mbps upload.

      Hi Steven,

      Thank you for getting in touch.

      The technology of Vividwireless is purpose built for data rather than mobile phone services, which means they do not include call or text services. They would fall under the mobile broadband category instead.

      Kind regards,
      Jason

    I’m on 2dollars a day plan with Optus pre-paid it’s unlimited everything for 2buks a day. The catch is if use ur credit it will charge 2 dollars but only 2dollars for that day. I don’t know if they still have this plan. Since I’ve had it for years now no doubt the best pre-paid plan Iv found all up 60 bucks a month but has unlimited internet. I use my hotspot all day and it only charges me 2 dollars. I don’t know Wat ur on about for not having unlimited in Australia

      Yes i am on the Optus $2 a day 3G ready plan. Had it for years and still loving it. I use it for personal hotspots and letting my friends go crazy on it. I use up to 30-50 gigs a month. Imagine the cost in comparison to today’s plans?

      Hi there,

      Thanks for your comment.

      Yes, as of this writing, Optus is still having the $2 Prepaid product with 4G Coverage, however, the data allowance included is only at 500MB (counted in 1KB increments) for use within Australia with 7-day expiry. Please note though that this offer and plan may change in the future.

      Most networks nowadays are generally not having unlimited data on their mobile data plans due to the huge number of mobile data users, which in turn could impair providers economically. Companies find that improving the data speed is costly to maintain. Although the data is not unlimited, most of these companies have dropped the outright data pricing and one example for that is the $2 Prepaid from Optus.

      Cheers,
      May
