Unlimited Phone Plans Compared


As anybody with a smartphone knows, mobile data is hugely important – for many it’s the key feature of their phone plan. With our increased demand for data has emerged a reduced reliance on simple text messages and good old phone calls – both of which are cheaper services for the telcos to provide.

As a result, more Aussie carriers are offering something that would have been but a pipe dream a few years ago – unlimited phone plans. Read on for our review of unlimited phone plans, or jump straight into our phone plan comparison tool to find a great unlimited deal.

What is an unlimited phone plan?

An unlimited phone plan includes infinite standard call time and text messages within the country the plan is paid for. This means plans are differentiated by what really matters to most consumers these days – data, media streaming and other bonus inclusions. While some expensive plans include unlimited international talk and text, the majority keep this limited to a national service.

Unlimited phone plans are available in both prepaid and postpaid form as SIM only plans. The majority of new handset phone plans also bring unlimited calls and messages as standard. A number of telcos now also provide unlimited data to use, which is pretty impressive, but there are a few catches.

So where can you find the best value plan? We’ve checked out the cheapest unlimited plans on the market to satisfy all of your usage needs. Remember that unlimited mobile data isn’t too common, so look at the amount of data on offer as the main point of difference when you compare plans.

Unlimited data phone plans

There are two providers that currently offer unlimited data on some phone plans and there’s probably no guessing as to what providers they are — Telstra and VodafoneOptus has in the past run an invitation-only offer for select Optus customers, where you paid $60 for ‘unlimited’ data at capped speeds of 1.5Mbps. While this offer isn’t currently available, it’s likely that Optus will roll this out or another unlimited data plan in the future.

Vodafone offers three different versions of its ‘unlimited’ plans. These plans, known as the ‘Plus’ plans (available as SIM-only and bundled with a handset) included a set amount of high-speed data and once you go over that data inclusion, you can keep using your data but capped at 1.5Mbps. The SIM-only plans are available for $45 with 30GB of high-speed data, $55 with 80GB of high-speed data and $65 for 120GB of high-speed data.

Telstra has eliminated excess data charges on all postpaid plans with unlimited capped-speed data available across all plans. Essentially once you reach your data inclusion, you can keep using your data with capped speeds at 1.5Mbps.

The following table shows all published Telstra and Vodafone postpaid plans with unlimited capped-speed data from Canstar Blue’s database, listed in order of advertised standard cost, lowest to highest, then by data allowance, largest to smallest.

Cheap unlimited phone deals

Most plans now offer unlimited standard national calls and SMS, on both prepaid and postpaid plans. While the cheapest plans usually cap the number of calls you can make, many telcos are now including unlimited calls on the cheapest plans. Some of these cheaper plans might run over  shorter term, like seven or 10 days, so you’ll need to check before you sign up.

Unlimited deals under $20 aren’t hard to find these days and many of them include at least 1GB of data. While some are available on 12-month contracts, you can find cheap unlimited plans on no lock-in contracts. There are also some plans with unlimited international calls, however these are usually to select destinations (as specified by the telco) and are generally only available on higher-level plans.

Prepaid plans

Unlimited phone plans with 100GB data

This is where the big telcos shine once again – Telstra, Optus and Vodafone. All three offer some form of phone plan with 100GB+ full-speed data included, either as a bonus or standard feature on the plans bundled with a new phone. Keep in mind you will likely pay $100+ a month for these plans, though at this price the handset is included often at no extra charge. If you’re looking at SIM-only, you might struggle to find a plan with over 100GB of data as most of the plans over 100GB are only available when bundled with a phone.

Vodafone currently offers 120GB of data on the $65 SIM Only and SIM Only Plus plans — the difference is the Plus plan includes unlimited capped data (at 1.5Mbps) after you use your 120GB of high-speed data, while the SIM Only version will charge excess data once you go over 120GB.

Overall, a phone plan is more than just a phone plan these days. If you go with one of the big providers, it also pays to look at the bonuses on offer. The table below shows a selection of Telstra, Optus and Vodafone postpaid plans from Canstar Blue’s database with a minimum of 100GB data, listed in order of advertised standard cost, lowest to highest, then by data allowance, largest to smallest.

Cheap unlimited iPhone plans

To bundle in an iPhone, especially the latest model, you can expect to pay over $70 a month for the most part and this is usually bundled with the lowest-level plan with around 2GB-4GB of included data. Only the big three telcos —Telstra, Vodafone and Optus— offer iPhones to bundle with plans. However, all three have found ways to reduce your monthly device payment costs, but there are some catches.

Vodafone is generally the cheapest each month, but this is only if you’re willing to commit to a 36-month payment plan. How Vodafone works is that it separates the device payment from the plan, so you can choose between a 12, 24 or 36-month payment period and then add on the phone plan of your choice. The longer the contract, the cheaper the monthly device payment. The catch with the phone plans is that, although the plan itself is a month-to-month plan, you will have to pay the outstanding handset costs if you cancel your Vodafone plan, however you can swap plans with no fees.

Optus is generally the second cheapest provider when it comes to bundling a phone plan with the latest iPhone. You can generally knock $10 off your device payment if you choose to lease the phone rather than the ‘own a phone’ option. The catch is that you’ll need to return the phone at the end of your term, or upgrade after a year for a nominal fee. If you’d rather own your phone, you’re looking at $90 or above for the cheapest plan combined with the latest iPhone on a 24-month contract and that’s with the cheapest phone plan, which includes 4GB of data.

Telstra also separates phone payments from plans, with four no lock-in postpaid plans to choose from. Once you’ve selected whether you want to pay off your device over 24 months, then add on a plan for your monthly payment price. While the phone plans are no lock-in, you’ll still need to stay on a Telstra plan as cancelling altogether will require you to pay off the remainder of your handset.

What ‘unlimited’ phone plan should I go with?

While some low-cost prepaid and postpaid plans are still available with set amounts of included call and text value, it seems that the future is very much unlimited. With the big three telcos offering some form of ‘unlimited’ data, it looks like the new battleground will be in this space, and this may make it hard for the smaller guys to keep up. However, if you look into the various smaller telcos, you’ll see that many of them are starting to offer bigger chunks of data than before. Providers in other countries – such as the US and UK – offer unlimited data phone plans and have done for a few years now. In Australia though, it’s likely that the new battleground could be how much ‘full speed’ data each provider can offer, rather than plans with ‘unlimited’ capped speed data.

But back to the cheap plans and there are a handful of providers that all seem to pop up when you mention ‘cheapest’, and competition is certainly heating up. This has created a bit of a ‘price war’ and while providers are slashing prices and ramping up value, the customers stand to be the ones to benefit most. The great news is that you don’t have to spend a lot to get an unlimited phone plan – $10 or less can per month.

It all just comes down to how much data you want, which will dictate how much you pay. If you’re in no rush to sign up to a new plan, keep your eyes peeled for the next best deal.
