The best unlimited mobile data plans

There isn't really a truly unlimited mobile plan available in Australia right now, though there are plenty that let you do away with excess data charges. 

There's always a catch or caveat of some sort. It just might not be measured in gigabytes. Depending on your data needs though, you might not mind the difference between the unlimited 20Mpbs plans like the one available through Felix Mobile and the endless data options available elsewhere.

Telstra, Optus, Vodafone, and Belong have all moved to this model for their postpaid plans. Vodafone even has endless data available on prepaid.

Before we get into our picks for the best unlimited plans, here's a selection of some of the most popular unlimited and endless data plans available in Australia.

The big three telcos (Telstra, Optus, and Vodafone) offer endless, speed-capped data in place of excess data charges on their mobile plans.

Felix Mobile also has an unlimited data plan, but even that comes with a different caveat. Your speeds are capped at 20Mbps regardless of how much data you use.

Lastly, Belong has also recently moved to the "no excess charges" model. If you go over your primary allowance, you'll be able to keep using your plan but capped to speeds of 1Mbps. 

Felix Mobile is unique in that it only offers speed-capped endless data (as well as unlimited calls and text), whereas other telcos 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.

The only other caveat to using Felix is that it uses Vodafone 4G. Vodafone reaches a good chunk of Australians these days but it's still the smallest network when compared to Optus and Telstra. Still, this $35 SIM only plan is still easily the best option currently available for people looking to hop on an 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 "FELIX" at checkout, you can score your first month with the provider for free.

After a couple of years of flirting with "endless" and "infinite" data plans, Vodafone finally went and introduced a truly unlimited data plan. None of that endless data that maxes out at 2Mbps - just unlimited full-speed data.

Alas, life comes at you fast. As of January 2023, Vodafone has amended its top-end "unlimited" plan to include the same limits found across the rest of its roster. You get 300GB of high-speed data each month, with everything after that capped at speeds of 2Mbps.

This plan will set you back $65 per month at full price, which, in addition to 300GB of data, includes unlimited talk and text in Oz, unlimited international calls to Zone 1 countries (and 300 minutes to Zone 2 countries), and if you're not happy with the service, you can get your money back within 30 days.

The only catch is that there's a 30GB monthly limit for using your phone as a hotspot for other devices. Exceed that and your hotspot 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.

The $68 Medium Upfront Plan from Telstra offers 180GB of "max speed" data, unlimited calls and text, data-free Apple Music streaming, 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.

Where Felix Mobile's endless data is a flagship feature of the plan, Telstra's is more like a fall-back option for when your data runs dry.

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

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 $49 Choice Plan. It only offers 30GB 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).

Looking for a cheaper source of endless data on the Telstra network? Telstra MVNO Belong recently got rid of excess data charges on its mobile plans. If you go over your data allowance, you'll be able to use unlimited data capped to speeds of 1Mbps. 

That's a bit slower than what other providers offer, but still enough for basic browsing. If you want to buy faster data, you can purchase an extra 5GB for $10. 

This applies to all of Belong's mobile plans, so we've picked the 100GB option for our top plan. At $45, it's still cheaper than the cheapest unlimited data options available from heavy hitters like Telstra and Optus.

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

If the Large plan is a bit beyond your budget, our next best pick when it comes to Vodafone is the $55 Medium Plan, for a number of reasons.

Firstly, it offers endless data speeds of 2Mbps, but most importantly, it also offers a hefty 150GB of high-speed data. That's way more than most Australians use on their mobile plans, but if you do burn through that, you will only be throttled to 2Mbps. It also offers the usual unlimited calls and text inclusions, along with 5G access and a bonus data of 150GB for students.

This is a month-to-month plan, but you can commit to a longer arrangement if you want to add a phone to your plan at any stage.

Vodafone offers different tiers of data on every SIM plan. Here's a look at each plan.

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.
