The best Optus mobile plans (August 2025)

Optus Small Choice Plus | 50GB Data | AU$40p/m (for 12 months, then AU$55 p/m)

While this plan normally costs AU$55 p/m, the AU$15 p/m discount for the first 12 months makes it a more compelling option than Vodafone's most affordable plan. You get 50GB of data, which is much more than most Aussies use in a month, as well as the ability to opt for an eSIM. The medium plan is also receiving this AU$15 discount – bringing it down to just AU$50 p/m on the first 12 months for 200GB of monthly data. These deals are only available for new services.

Total minimum cost: AU$40 | Cost over 24 months: AU$1,140

iPhone 16 (128GB) | 50GB Data | 24 Months | AU$98.29 p/m (for 12 months, then AU$113.29 p/m)

The iPhone 17 is set to release in a few months, but now is a great time to upgrade to the iPhone 16. Optus is offering the iPhone 16 for less than AU$100 p/m thanks to its AU$15 p/m off for 12 months SIM plan deal. In our iPhone 16 review, our tester said that it elevated " the base [iPhone] to new heights" with new colours, buttons and an AI platform. Powered by Apple's speedy A18 chip, with two excellent cameras and an entirely new Camera Control button, the iPhone 16 is a great choice for folks who don’t need to go Pro.

Total cost over 24 months is AU$2,534.96

Samsung Galaxy S25 (256GB) | 50GB Data | 24 Months | AU$85.78 p/m (for 12 months, then AU$100.78 p/m)

There's lots of competition when it comes to the best Android phone for most people, but we've opted to recommend the Galaxy S25 over the Pixel 9. Combined once again with the Choice Plus plan from Optus, you get an incredible smartphone at a relatively affordable monthly price. It might not be the best camera phone on the market, but it's better than its predecessor in almost every way – and beats the iPhone 16 in performance and battery life.

Total cost over 24 months is AU$2,238.72

iPhone 16e (128GB) | 50GB data | 24 months | AU$81.61 p/m (for 12 months, then AU$96.61 p/m)

While we've previously recommended the iPhone 14 or iPhone 13 for those who want to upgrade without breaking the bank, there's a new kid on the block. The iPhone 16e beats a discounted iPhone 15 for the title of the best budget iPhone you can buy, offering better battery life than the iPhone 16 and Apple Intelligence features that the iPhone 15 does not support. For just over AU$80 p/m on the first 12 months, it's an excellent choice if you want a current-gen iPhone experience on a budget.

Total cost over 24 months is AU$2,138.64

Samsung Galaxy A56 (128GB) | 50GB data | 24 months | AU$69.10 p/m (for 12 months, then AU$84.10 p/m)

Offering more value than iPhone 16e and Google Pixel 9a thanks to their more expensive price points, the Samsung Galaxy is the best cheap phone you can buy – and that doesn't change when pairing it with an Optus plan. While it doesn't possess enough power for serious mobile gamers or those who need to edit 4K video on their mobile, it is easily the top option for most people – offering excellent performance across its design, cameras and software. It even has helpful AI features despite lacking the full Galaxy AI suite.

Total cost over 24 months is AU$1,838.40

iPhone 16 Pro (128GB) | 50GB Data | 24 Months | AU$99.68 p/m (for 12 months, then AU$114.68 p/m)

The 6.9-inch frame of the iPhone 16 Pro Max may not be for everyone, which is good, because the 16 Pro boasts the same power in a much more manageable size. For less than AU$100 p/m on the first 12 months, the iPhone 16 Pro makes no concessions for its pocket-sized brilliance, making it a giant leap for anyone still using an older model. In our iPhone 16 Pro review, we were slightly disappointed with Apple Intelligence as a whole, but the only phone-specific flaws we could find was the fact that it has an 128GB storage model and we've seen sharper screens for the price.

Total cost over 24 months is AU$2,572.32

Samsung Galaxy S25 Ultra (256GB) | 50GB Data | 24 Months | AU$91.34 p/m (for 12 months, then AU$106.34 p/m)

Grabbing the S25 Ultra for only AU$91.34 (and then AU$116.34 p/m after 12 months) is an absolutely stellar price. The Samsung Galaxy S25 Ultra comes with a Snapdragon 8 Elite chip and 12GB RAM, and it's an upgrade over its predecessors in every way – unless you dislike the more rounded design. We called it the "ultimate Android" in our Galaxy S25 Ultra review, falling in love with its massive screen, powerful AI and battery life to match the 'Ultra' name.

Total cost over 24 months is AU$2,372.16

Samsung Galaxy Z Flip 7 (256GB) | 50GB Data | 24 Months | AU$102.43 p/m (for 12 months, then AU$117.43 p/m)

If you're looking to grab Samsung's latest and greatest flip phone, Optus is the telco for you – offering the cheapest monthly repayment thanks to its AU$15 p/m discount on the first 12 months. The phone that convinced our tester that "flip phones are the best phones", it earned 4.5 stars in our Samsung Galaxy Z Flip 7 review thanks to its incredible cover display, power, DEX support and fantastic AI-powered photo editing.

Total cost over 24 months: AU$2,638.32

Samsung Galaxy Z Fold 7 (256GB) | 50GB data | 24 months | AU$148.27 p/m (for 12 months, then AU$163.27 p/m)

If you're seeking the ultimate tablet and phone in one, the Galaxy Z Fold 7 is the new best choice. In our Samsung Galaxy Z Fold 7 review, our tester said that it "might just be the perfect foldable", boasting an incredible 200MP camera and the thinnest Z Fold design yet. Its 8-inch display is larger than its predecessor, too – rivalling the 8.3-inch iPad mini. On top of a discounted SIM plan, buying through Optus also nets you the Galaxy Watch 8 for free when connected to a 24 or 36-month plan.

Total cost over 24 months: AU$
