For those who watch YouTube videos on their phones, regularly upload stories and photos to social media or want to binge-watch Netflix shows on the go, worrying you’ll run out of data can be a constant stress. So, can you solve this by opting for an unlimited mobile data plan?

The short answer is that while there aren’t any truly ‘unlimited’ mobile data plans,  you can come close to this with the wide range of high data phone plans available.

Let’s get down to the details.

Why don’t telco providers offer unlimited mobile data on their plans?

According to the 2018 ACCC decision on false and misleading advertising for telcos, providers including Optus, Telstra and Vodafone are no longer allowed to market their plans as offering ‘unlimited’ mobile data. In reality, there is a definite 1.5Mbps speed cap placed on customers’ usage after they’ve exceeded their prescribed data allowance i.e. with ‘peace of mind’ data.

Best ‘unlimited’ data overall

Vodafone’s $80 Red Plus Plan tosses up an enormous 150GB for $80 per month, as well as unlimited national calls and text minutes, unlimited international minutes to Zone 1 countries and 300 minutes to Zone 2 countries.

What does ‘unlimited’ data really mean?

While Vodafone promotes the Red Plus Plan as providing ‘endless’ data, you should know that once your 150GB data allowance has been used up, any additional data you use will be subject to a data speed cap of 1.5Mbps till your next recharge.

You can sign up to the $80 Red Plus Plan either by bundling your mobile data plan with one of 39 available handsets (with 24-month or 36-month handset repayments) or opting for a 12-month contract, BYO phone SIM-only plan.

Here are more ‘unlimited’ data plans sorted by plans with the most data:

Best Optus ‘unlimited’ data

The Optus One plan offers a whopping 500GB for $119 per month. While Optus’ new plan is definitely pricey, it’s a tradeoff for gaining access to Optus’ priority network and at the time of writing tosses up the largest data allowance of monthly mobile data plans. 

With this plan, you’ll also get an optional Optus Sport subscription and 12 months free Apple Music trial so at least you don’t have to pay more for some additional streaming services. 

The biggest downside of choosing an Optus ‘unlimited’ data plan is that unlike Vodafone and Telstra’s ‘endless’ data which come with the 1.5Mbps speed cap, with Optus, there are excess data charges once you’ve hit your monthly data allowance. For example, every extra 1GB over the 150GB allowance on this plan will cost you $10.

For those that don’t have a need for this much data but are dead set on Optus, you might want to consider one of the Optus Choice Plans: either the $79 for 120GB or $59 for 100GB monthly data plans are available as SIM-only, BYO phone plans or no-contract device bundle plans available with 47 phone models on 24-month or 36-month repayment.

Best Telstra ‘unlimited’ plan

Telstra’s $100 Extra Large Mobile Plan will give you an enormous 150GB for $100 each month with no excess data charges as well as data-free streaming of Apple Music and several sports programs. 

You’ll also have the chance to nab free 5G network access as long as you’re in an 5G area and get a 5G-compatible modem. 

Similar to Vodafone, Telstra doesn’t have excess data charges, however your mobile data plans will be subject to a speed limit of 1.5Mbps once you’ve exceeded your monthly data allowance.

How slow is an internet speed of 1.5Mbps?

With an 1.5Mbps data speed, you’ll be able to carry out basic internet and social media browsing, music service streaming and potentially streaming videos in standard quality. 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 4G download speed is around 39Mbps while 3G sits around 6Mbps on average.

Best cheap ‘unlimited’ data plans

Vodafone’s $40 Red Plus Plan provides 7GB for $40 per month at maximum speed and is the cheapest mobile data plan you can get that will give you ‘unlimited’ data. Like the other Red Plus plans above, you’ll be subject to a speed cap of 1.5Mbps once you’ve used up your data allowance.  While 7GB isn’t a massive amount for monthly usage, this is probably sufficient for the average user who can rely on home/work WiFi throughout most of the day.

For those keen to snag a bargain, Vodafone is offering a bundle and save deal on all its Red Plus Plans, which could make this ‘unlimited’ data plan most attractive for those looking to maximise their savings. The Bundle & Save deal entails a 5% to 20% discount off your plan costs when you pool together multiple eligible plans under one account.

For those willing to fork up more a bit more for extra perks and benefits, also consider the Telstra $60 Medium SIM Plan for 100GB monthly. Available as either a BYO phone, SIM-only plan or as a no-contract phone plan with 24-month or 36-month handset repayments, you’ll also receive data-free streaming of Apple Music and select data-free sports streaming. 

To give you an idea of how this weighs up to other monthly plans within this price range that don’t qualify as ‘unlimited’, Optus MVNO Circles.Life is tossing up a 60GB monthly plan for $38, while amaysim provides a sweet steal with its $30 UNLIMITED Plan for 30GB per 28 days. If you don’t mind opting for a plan on contract, Moose Mobile’s 46 SIM Only 80GB monthly plan for $46 is good value too.
