The best unlimited data mobile plans (February 2025)

Unlimited mobile data in Australia typically means no excess charges. If you use up all your data, you'll be able to keep using your plan at slower speeds, without paying anything extra.

Below are the most popular plans with unlimited mobile data you can in Australia right now.

A small number of providers offer unlimited mobile plans in Australia. Telstra, Optus, Vodafone, Felix Mobile, Belong, and Dodo all have mobile plans that you could call "unlimited", but there are still caveats to be aware of. 

While these plans have unlimited data option, the catch is usually speed. After you go through your primary data allowance - the 50GB, for example, your plan comes through - you'll get unlimited data but at a slower speed. Typically 1.5Mbps. 

Telstra, Optus, Vodafone, Dodo, and Belong have all moved to this model for even some of their cheapest mobile plans. Vodafone even has endless data available on prepaid.

Felix Mobile is an interesting alternative, where you get truly unlimited data, but you're restricted to speeds of 20Mbps. That's a lot faster than 1.5Mbps, but not quite as fast as a normal plan, where speeds can easily hit 100Mbps.

Felix unlimited Mobile Plan

pro
Reasons to buy
  • Only true unlimited plan
  • Unlimited calls
  • Access to 5G network (Vodafone)
con
Reasons to avoid
  • Speeds capped at 20Mbps
  • No international calls included

Felix Mobile is unique in that it offers a mobile plan with speed-capped endless data (as well as unlimited calls and text), whereas other telcos typically offer an allotted monthly amount of "max speed" data that is throttled after a limit is reached. Throwing in with Felix means getting endless ( aka unlimited) data so long as you're happy to limit yourself to 20Mbps.

Felix uses the Vodafone network. Vodafone reaches a good chunk of Australians these days but it's still the smallest network when compared to Optus and Telstra. Still, this $40 SIM-only plan is still easily the best option currently available for people looking to hop on a truly endless data plan at a comparatively cheap price.

Felix Mobile is not entirely without limits, but it's easily the closest thing Aussies can find to a genuinely unlimited mobile plan right now. Even better, if you enter the promo code "FELIX50" at checkout, you can score your first three months with the provider at 50% of the usual price.

Felix also has two cheaper more conventional plans. These plans have a primary data allowance. After you go over this, you'll get unlimited data at 1.5Mbps. 

Here's Felix's full range of plans: 

Best cheap unlimited data mobile plan

Belong 25GB Mobile Plan

pro
Reasons to buy
  • Unlimited Databank + Data Gifting
  • Access to 5G network
con
Reasons to avoid
  • Not a lot of high-speed data
  • Download speeds up to 150Mbps
  • Access to Telstra's wholesale network only

Telstra's budget brand Belong's mobile plans offer the same kind of endless data as Telstra, Optus and Vodafone.

Our pick for the best cheap unlimited plan is the Belong 25GB Mobile Plan. This plan comes with unlimited national calls and texts, 25GB of monthly data, data banking, and data gifting. If you manage to get through your 25GB of data, and anything sitting in your data bank, you'll still stay connected at speeds of 1Mbps until your plan resets.

Since Belong is a Telstra MVNO, it has coverage on the Telstra wholesale network. This is a little smaller than the full Telstra network, with less coverage in some very remote and rural areas. The coverage is still better than you'll get on Optus and Vodafone, however. 

If the above isn't the right fit, be sure to check out the other Belong mobile plans with excess-charge-free data below:

Best unlimited data mobile plan from Optus

$52 Optus Choice Plus Plan

pro
Reasons to buy
  • Data Gifting
  • Access to 5G network
con
Reasons to avoid
  • More expensive than MVNOs
  • No international calls included

Like Telstra, every Optus SIM-only plan offers endless data with comparatively slow speeds of 1.5Mbps after you hit your included data limit.

Our top plan pick for Optus is the $52 Choice Plan. It only offers 50GB of max speed data (plus unlimited calls and text) but if it's endless data you're after, and you can bear the 1.5Mbps cap, it's no different from what plan you're already on.

There are plenty of other Optus SIM plans with more max speed data, but at that point, you're probably better off going with a provider like Circles.Life and getting more bang for your buck. Circles.Life doesn't offer endless data, but it does give you a lot of data for cheap on the Optus 4G network. 

Otherwise, and if it's Optus you're after, here's a quick look at each plan (all with endless data capped at 1.5Mbps).

Best unlimited data mobile plan from Vodafone

Vodafone $49 Small Plan

pro
Reasons to buy
  • Unlimited calls to select countries
  • Highest speed cap after main data has been used
  • Access to 5G network
con
Reasons to avoid
  • Smallest network

Vodafone has varied 'endless data' speed caps - the more you spend, the more data you get, and faster speeds thereafter. In short, the less likely you are to need that unlimited data, the faster it will be.

Our best pick is the $59 Medium Plan. In addition to 180GB of data, the plan includes unlimited talk and text in Oz, unlimited international calls to Zone 1 countries (and 300 minutes to Zone 2 countries), and Vodafone is currently running a promotion where you'll get 3 free months of Binge when you sign up.

If you somehow exceed your 180GB of data, your data will be slowed to 2Mbps. Our guess is that Vodafone is trying to prevent customers from using the plan to replace their home internet.

Best unlimited data mobile plan from Telstra

Telstra $65 Basic Upfront Mobile Plan

pro
Reasons to buy
  • Data Gifting + some international calls
  • Access to 5G speeds
  • Biggest network
con
Reasons to avoid
  • Expensive

The $65 Essential Upfront Plan from Telstra offers 50GB of "max speed" data, unlimited calls and text, discounted movie tickets for Event Cinemas, and 5G access on Australia's biggest mobile network.

It's also free of excess data charges, meaning that if you exceed that cap you won't be charged extra money. Instead, your speeds get slowed to 1.5Mbps. That's a significant hit to your download and upload speeds, and you'll definitely notice the difference.

Every Upfront Telstra plan offers 1.5Mbps of endless data. Here's a quick look at each plan.

Best unlimited data mobile plan from Dodo

Dodo $23 mobile plan

pro
Reasons to buy
  • Cheap! 
  • Comes with some international calls 
con
Reasons to avoid
  • Unlimited data speeds capped to a slow 256Kbps
  • 4G only

Looking for a cheaper source of endless data? Dodo's $23 mobile plan is worth considering. 

The plan comes with 15GB of data, and if you go over it, you'll get unlimited data at speeds of 256Kbps. That is quite slow, however. You might be able to get some basic web browsing in, but it won't feel great. 

Dodo's plan also has unlimited talk and text, and $100 of international call credit.

Dodo mobile plans are powered by the Optus network.

If you'd prefer another option, here is Dodo's full range of SIM-only plans:

Expert Advice
In Australia, unlimited data typically means no excess charges. You’ll still get a data allowance, and then after you go through that, you can keep using your plan at much slower speeds. While an unlimited data plan is a great way to prevent bill shock, make sure you still choose a data allowance that meets your needs to avoid being stuck on very slow internet.”

How much does unlimited mobile data cost?

At the time of writing, Belong has the cheapest mobile plan with unlimited data. The $29 plan comes with 25GB per month included, and unlimited data capped at 1Mbps thereafter.

Otherwise, the price of an unlimited data mobile plan varies provider to provider, as do the specific strings attached to that promise of endless downloads on the go.

Is unlimited mobile data truly unlimited in Australia?

Signing up for an unlimited data plan will indeed get you as many gigabytes as your heart desires. However, the speed at which you get that data will vary with the plan and provider involved.

Each "unlimited" or endless data mobile plan in Australia comes with different terms and conditions. That said, the way that they tend to work isn't all that different from traditional data-capped mobile or internet plans.

You'll get a monthly allowance of "max speed" data to use. Once you use that up, you'll remain connected to the network and you won't be hit with any excess data charges. Instead, your connection will be throttled down to a lower speed. The exact speed depends on your provider and plan, but most tend to speed cap at around 1.5Mbps.

Can I use unlimited mobile data if I'm overseas?

You can't use unlimited data while overseas. Instead, you'll need to purchase an international roaming pack from your provider, if they offer one.

How we choose the best unlimited data plans

There are a number of considerations when we look at the best plans with unlimited or endless data. Price is a key factor, we want to make sure we're displaying plans that offer value for money.

We also look at what the capped speed will be, as well as how much data is included at the max speed.

Unlimited mobile data plans FAQs

How slow is 1.5Mbps exactly?

With a 1.5Mbps speed cap, you’ll be able to carry out basic internet and social media browsing, music service streaming and potentially streaming videos in standard definition. You’ll probably find that pages will take significantly longer to load and you might have to wait for videos to buffer. In comparison, the average uncapped download speed on 4G is around 39Mbps while 3G downloads sit around 6Mbps on average.

Does Optus have an unlimited data plan?

All of Optus' postpaid mobile plans come with an inclusion that the provider calls Endless Data. This works the same as the "no excess data charge" offering found with Vodafone and others.

Your plan comes with a set data allowance. Once that's been used up, you'll get unlimited data at slower speeds of 1.5Mbps.

Does Telstra have an unlimited data plan?

All of Telstra's postpaid - or "Upfront" - mobile plans are free from excess data charges. Once you go over your primary data allowance, you'll be able to keep using the plan with unlimited data but at a slower speed of 1.5Mbps.
