Feeling the pinch of high phone bills amidst Australia's ongoing cost of living crisis? Relief is available! Beyond the major carriers like Telstra, Optus and Vodafone, several providers now offer mobile plan options for all budgets.
It's no secret that the bigger mobile providers come with a higher price tag for their extensive data plans and added features, but thankfully there are cost-effective alternatives. Smaller providers, called mobile virtual network operators (MVNOs), utilise the exact same major networks.
This allows them to provide phone and data services at a much lower cost, with nearly identical coverage — though speeds might be capped at times. If you're looking to save on phone bills, consider checking out options like Boost Mobile, TPG, Kogan Mobile, Belong, Tangerine Telecom and Aldi Mobile.
How cheap are we talking? You can get SIM-only plans with unlimited national calls and texts, along with a good amount of data, starting at just AU$12.50 a month! Keep in mind, though, some of these super-cheap deals are promotional offers, and the price might increase after an initial period, typically around six months.
The value you get really comes down to whether you choose a prepaid or postpaid plan and what fits your budget. The good news is there are plenty of ‘no contract’ options out there — some even offering surprisingly generous data allowances. Here’s a look at the best affordable mobile plans in Australia.
Best cheap plans (20GB minimum)
If value is what you're after, it's hard to overlook TPG's excellent 25GB Small Plan, which offers 25GB of monthly data at the half-off price of AU$12.50p/m for the first 6 months. While the price will go back to AU$25 per renewal after this period, it's still very affordable for what you're getting.
For an affordable mobile plan with a generous data allowance, consider TPG's 25GB Small Plan. Currently, you can get it for half price at AU$12.50p/m for the first six months, after which it reverts to the standard AU$25p/m. TPG utilises the Vodafone 4G network for this entry-level plan and, like most MVNOs, caps speeds at 150Mbps.
Total minimum cost is AU$12.50 | Total cost for first year: AU$225
50GB SIM only plan | 50GB | AU$18 p/m for first 4 months, then AU$36 ongoing | Telstra 5G network
New customers who sign up for a Tangerine 5G SIM-only plan before the end of the month can halve their monthly bill for the first 4 months, reducing the price of the 50GB plan from AU$36 p/m to just AU$18 p/m. Tangerine's half-price promotion is available until March 31, 2026. T&Cs apply.
Total minimum cost is AU$18 | Total cost for first year: AU$360
Those looking to keep costs down shouldn't overlook this budget-friendly deal from Moose Mobile, which offers 30GB of monthly data for just AU$12.40 for the first 6 months of connection, after which the price go up to AU$24.80 p/m, which is still excellent value.
Total minimum cost is AU$12.40 (1 month) | Total cost for first year: AU$223.20
Best cheap big-data plan
Looking for massive data at a bargain price? Yomojo's Pro Plan delivers incredible value. For the first six months, it's an absolute steal at only AU$29.90 per renewal, translating to a mere AU$0.28 per GB. Even after the introductory period, when the price adjusts to AU$34.90 every 30 days, it remains a fantastic deal, breaking down to just AU$0.33 per GB. This promotion is available until January 31, 2026, so this is your last chance to secure this deal before it expires. T&Cs apply.
Total minimum cost is AU$29.90 (1 month) | Total cost for first year: AU$388.80
If you're looking for a reliable prepaid plan that comes with stacks of data, Superloop's Plus 5G Plan is worth considering. It offers access to Telstra's 5G network, providing 130GB of data as standard — all for just AU$50 over 30 days with automatic recharges. And as an added bonus, new Superloop mobile customers (and existing Superloop broadband customers signing up for a mobile plan) get their 2nd recharge for free. Another major perk is the ability to roll over up to 500GB of unused data. Offer valid until withdrawn. T&Cs apply.
Total minimum cost is AU$50 (30 days) | Total cost for first year with free 2nd recharge: AU$550
Cheap mobile plans: what to look for
When choosing an affordable mobile phone plan, value for money is paramount. While most plans now offer unlimited national calls and texts, the key is to strike a balance between cost and data allowance. Often, a small increase in price can lead to a significant boost in your monthly data limit.
However, price isn't the sole consideration. It's crucial to identify the mobile network your discount carrier utilises, as smaller telcos offering the cheapest plans don't operate their own networks. Instead, these Mobile Virtual Network Operators (MVNOs) lease access to networks built by Australia's three major carriers: Telstra, Optus or Vodafone.
Consequently, your local coverage quality will likely depend on the major carrier network your chosen discount telco uses. Therefore, before committing to any plan, always confirm the major carrier network it operates on and verify the service in your area.
Our best cheap mobile phone plan search takes into account the merits of prepaid vs postpaid phone service, while also examining whether MVNOs are worth the money.
How we pick the best cheap cell phone plans
We're constantly looking at what Australian telcos offer as part of our research into the best mobile phone plans. That includes examining what's available from the major carriers — Telstra, Optus and Vodafone — as well as from smaller telcos which run on these carriers' networks. We check prices monthly, comparing what different services have to offer.
For our best cheap mobile plans guide, we set a jumping off point of around AU$12.50 per month, along with a monthly data limit of at least 20GB. Price is of the utmost importance in our rankings, though we've made an effort to steer you away from some very cheap plans which we believe don't offer good value for money.
Our decisions take into account how much data each plan provides, and we've even calculated the average daily allowance and price per MB before coming to our conclusions, and we've also taken note of any perks to keep in mind. That can help distinguish two equally priced plans — or even highlight that a slightly more expensive plan offers better value overall.
