Best mobile phone plans in Australia

Each month, we pick the best mobile plans from our database of more than 30 mobile providers. The categories include SIM-only (postpaid), prepaid, international calls, kids phone plans, iPhone plans, and Samsung Galaxy plans. Scroll on to discover the best mobile plans for August 2025.

Some of the best mobile phone plans in Australia are postpaid SIM-only picks. SIM-only plans let users pay at the end of the month. The more you pay, the more data you get. This month, Dodo has our pick for best SIM-only plan.

Plan basics:

• Data: 40GB
• Monthly: $16.50/mth for the first four months, then $33 per month ongoing
• Total cost over first 24 months: $726
• Network: Optus 5G

Dodo's $33 Mobile Plan this month's pick for best SIM-only postpaid plan. It comes with a healthy 50GB and new customers get 50% off for the first four months for new customers who sign up before September 30. As for the standard price, $33 is pretty competitive for this much data.

If you go over your data cap, there are no automatic overage fees. Instead, Dodo limits your speed to 256Kbps,. That's extremely slow, but you can always opt to purchase additional data. Unlimited data banking is available on this plan, as is 5G. Plus you get $300 international call credit to use as you wish.

For popular SIM-only alternatives from our database, the plans below have at least 30GB of data.

For us, the best mobile plans for prepaid users are ones that include enough data for everyday and heavy users, which is why we look for one with at least 30GB of data. This month, Felix has our pick for best prepaid plan.

Plan basics:

• Data: 50GB
• Intro cost: $15/mth for first three recharges, then $30 ongoing
• Total cost over first 24 months: $675
• Network: Vodafone 5G – capped at 150Mbps
• Prepaid expiry: One month

felix's 50GB Mobile Plan this month's pick for best SIM-only postpaid plan. It comes with a healthy 50GB and a three-month intro discount if you use code FELIX50 – though its ongoing price of $30 is also competitive for this many gigabytes. And there are no overage fees for excess data. Instead, you're capped at 1.5Mbps for the rest of your billing period and can opt to purchase additional data if you need it.

The plan includes 5G, though the Vodafone network does have the lowest 5G coverage. But if you live in a large population centre you should be fine. And these days Voda's 4G footprint is almost identical to Optus, so no worries there.

Some of the best mobile phone plans in Australia have international calls. TPG is a regular monthly winner for best mobile plan with international calls because its 50GB plan is fairly competitive for this much data, plus it's one of the few with unlimited international inclusions for talk and text (to 31 selected destinations).

Plan basics:

• Data: 50GB
• Intro cost: $17.50/mth for first 6 months, then $35/mth ongoing
• Total cost over first 24 months: $735
• Network: Vodafone 5G (150Mbps)

The TPG 50GB Medium Plan is a prepaid plan that acts like a SIM-only one, thanks to monthly recharges. New customers pay $17.50 per monthly renewal for the first six, before the prepaid plan reverts to its typical $35 monthly recharge fee. TPG NBN customers can save $5 per month by bundling their internet with this prepaid plan. Whichever price you’re paying, this TPG prepaid plan includes unlimited talk and text in Australia, plus 50GB of Vodafone 5G data (capped at 150Mbps).

Specific to this category, this TPG plan also includes unlimited call minutes to 31 selected destinations: Bangladesh, Brazil, Canada, Chile, China, Colombia, Germany, Guam, Hong Kong, Iceland, India, Indonesia, Ireland, Italy, Japan, Malaysia, Mexico, Netherlands, New Zealand, Norway, Peru, Puerto Rico, Romania, Singapore, South Korea, Spain, Taiwan, Thailand, United Kingdom, United States of America, and Vatican City.

If this plan doesn't suit your needs, the list below includes other popular plans from our database with various international calling inclusions.

The best phone plans for kids give parents control over spending, which means prepaid over SIM-only. These prepaid plans offer a bit of data with unlimited talk and text in Australia. This month, Kogan Mobile has our pick for best mobile plan for kids.

Plan basics

• Data: 15GB
• Price: $20 per renewal with no eventual price jump
• Total cost over first 24 months: $540
• Network: Vodafone 4G
• Prepaid renewal: 30 days

The Kogan Small Monthly Plan is our current pick for best phone plan for kids. It has a decent data allowance and good ongoing pricing. But mostly, the lack of intro discount means you don't have to break out the calculator to plan your budget.

The plan is fairly no frills, lacking perks like data rollover or affordable roaming. But you can add 100 international minutes to 32 selected countries for $5 per recharge. The connection is limited to 4G, but to be honest that's more than fast enough for phone usage and your little ones won't be disadvantaged when it comes to phone or SMS reception (which both operate exclusively via 4G). This plan also supports eSIM devices. And if you're concerned about Vodafone coverage, it's roughly identical to Optus for 4G these days, thanks to a network sharing agreement between the two telcos (though for the most part, it still uses Vodafone's infrastructure where possible).

The first question to answer before getting to which mobile plan is right for you is whether you’re using an existing mobile phone or want a new one. If you want a new one, you’ll either have to purchase a compatible prepaid handset or pair a SIM-only mobile plan with a new iPhone, Samsung Galaxy, Google Pixel or other option. New-model mobile phones can be bought outright or paid off over 12, 24 or 36 months from participating telcos like Telstra, Optus and Vodafone.

For those happy to use their existing mobile phone, choose between prepaid or SIM-only mobile plans. Prepaid plans are great for people who want to control their spending and aren’t overly interested in perks. While prepaid plans are paid in advance of use SIM-only plans are paid at the end of a billing month (except for Telstra Upfront plans).

SIM-only plans are always monthly offerings, but prepaid mobile plans have a range of durations. The ones we cover on this page are roughly monthly, which can be 28 days, 30 days, or an actual month. But you can also get short-expiry (e.g. 7 days) or long-expiry prepaid plans, which can last up to a full 365 days.

With SIM-only mobile plans, you’re more likely to find telcos that offer data banking or data rollover for carrying over unused gigabytes or capped plan speeds if you exhaust your max-speed allocation. Coverage is an important consideration, too. Telstra has the largest mobile network followed by Optus and Vodafone. The latter two are almost identical in 4G coverage, but Optus has the wider 5G footprint. If you live in a populous part of Australia, the chances are good you can pick between all three.

That trio may be the respective network owners, but there are dozens of telcos that use their networks to offer more competitively priced plans. Effectively, you might be able to get the coverage perks of the network you want without having to pay a premium for it.

Pretty much every mobile plan comes with unlimited national talk and text, but other features like international calls and messaging are rarer. It’s a similar story for international roaming if you like to travel and want the option to use mobile data abroad. There are a range of other perks to help separate closely competing plans, with eSIM being one of the better ones that uses a digital SIM rather than needing to wait for a physical SIM card to arrive.
