If it's unlimited data, why are there still data caps on plans?

Here's where unlimited or "endless" data can get a bit confusing. Vodafone's and felix's 2 plans are the only truly unlimited plans on the market right now. The rest work as "endless" rather than unlimited data.

"Endless" data still means you can use as much data as you want each month without getting slammed with extra fees, but it does work a little differently.

mobile icon
1. Use your plan as normal.
Unlimited data icon
2. Switch to "endless" data when you reach your monthly data cap
Slow icon
3. Your mobile speed will slow down to between 1.5-20Mbps.
refresh icon
4. Plan resets at the end of the month.

Let's assume you're purchasing a plan that comes with a 40GB monthly allowance and "endless" mobile data. Here's how it would work:

  1. You use your mobile plan as you normally would, without having to worry about getting charged for excess data since your plan is "endless".
  2. Once you've used up your monthly allowance (in this case, 40GB), you'll automatically be switched over to your "endless data". This will come with a speed restriction between 1.5-20Mbps depending on your plan.
  3. Keep using your phone and mobile Internet as you normally would. You won't get charged extra, but you might realise your speeds are slower than usual.
  4. At the start of the following month, your plan will reset and the steps above will come full circle once again.

Which is the best unlimited data mobile plan?

The best plan will depend on what you're after. The main difference will be if you're willing to accept a speed cap on your plan or not.

At the moment, you have 4 providers to choose from.

Vodafone logo

Vodafone unlimited mobile data plans

Vodafone is currently the only telco in Australia that offers a truly unlimited data mobile plan with no speed caps. You get:

  • Speeds averaging 39Mbps on its 4G network.
  • No excess data charges.
  • Unlimited international minutes to selected countries.
  • Watch out for: You're only allowed to hotspot 30GB of data, after which your speeds get capped to 2Mbps.

Vodafone also offers "infinite data" which works the same way as "endless data" across its other prepaid and postpaid plans. There are no excess usage charges on these plans, but be prepared for your speeds to get slowed down to 2-20Mbps depending on which plan you're on.

felix logo

felix unlimited mobile data plan

Compared to Vodafone, felix offers a more budget-friendly unlimited mobile data plan coming in at under half of Vodafone's price.

You'll get:

  • The same Vodafone 4G coverage at a lower price point.
  • Digital, Australia-based customer support.
  • A 100% carbon neutral provider that plants 1 tree per month for every active subscription.
  • The option to pause your subscription for up to 242 days.

Until December 14, you can get 50% off felix's mobile plan thanks to our Finder exclusive discount. Just use the coupon code 'FINDER50'.

  • Watch out for: felix's speed cap of 20Mbps. This speed should be fine for most people but may not be enough depending on what you're doing on your phone. As a point of reference, the average 4G speed in Australia is around 38.5Mbps, so felix's speed is about half of this.

Optus logo

Optus unlimited data mobile plan

Optus might be one to consider if you're not worried about speed caps as much as you are about excess data charges.

Once you've used up your monthly data allowance, Optus will drop your speeds down to 1.5Mbps.

With Optus, you'll also get:

  • Free access to Optus Sport and OS Fitness.
  • Data sharing across eligible Optus Choice Plans under the same account.
  • 5G network access for compatible devices.
  • Watch out for: 1.5Mbps is pretty slow. If you're not keen to get hit with this speed cap, make sure you choose a monthly data allowance that is enough to cover all your full mobile speed needs.

Telstra logo

Telstra unlimited data mobile plans

Similar to Optus, Telstra also offers endless data plans. Your speeds get capped at 1.5Mbps once you've used up your monthly data allowance. You'll also get:

  • The widest 4G network coverage in Australia – Telstra reaches 99.5% of the Aussie population which is great for regional and rural areas.
  • Unlimited international text messages.
  • Data sharing between eligible plans linked to the same account.
  • Watch live sport, data-free.
  • Watch out for: 5G network access is only available to those on Telstra's Medium Upfront Mobile Plan or above.

Do I really need an unlimited mobile data plan?

If you're on the move a lot, or want a backup for your home Internet when there's an outage, then maybe.

  • Good to know: According to the ACCC, the average Aussie uses 25GB data, which suggests that you probably don't need unlimited data.

We suggest calculating how much data you need each month before spending extra dollars on a mobile plan you might not need.

If it turns out that you do use heaps of mobile data, you could still opt for a high data mobile plan instead. You can still find great data options for under $35 a month if you don't need unlimited.

    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 to that day when we can use unlimited data on our mobile phone plans. Just to clarify some points though, it is not the only US that uses “capping” on their unlimited offers. Many providers, including the ones in Australia, are doing that in compliance with the Fair Usage Policy (FUP), which 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
