The best Optus mobile plans in 2026

Optus Promo Plan | 360GB Data | AU$69p/m (for 12 months, then AU$79 p/m)

I've selected the Optus Promo plan as, on paper, it offers the best overall value right now. For AU$69p/m for the first 12 months, you get 360GB of data each month, AU$10 of credit to put towards subscriptions via Optus' SubHub service and unlimited international calls and texts.

Total minimum cost: AU$69 | First year cost: AU$828 | Ongoing yearly cost: AU$948

iPhone 17 (256GB) | 50GB Data | 24 Months | AU$113.29 p/m + Apple Watch SE 3 for AU$0

As our iPhone 17 review states, this is the best-value iPhone ever, serving up Pro-level features, plenty of power and a gorgeous display. I've singled out a 24-month plan, but you could pay less each month for the phone by opting for a 36-month contact. You can also grab a free Apple Watch SE 3 if you sign up by February 11.

Total cost over 24 months is AU$2,718.96

iPhone Air (256GB) | 50GB Data | 24 Months | AU$109.09 p/m + Apple Watch SE 3 for AU$0

The iPhone Air has perhaps not been quite the success Apple was expecting, but there's no denying it's a gorgeous device that has a lot going for it. It might only have a single camera, but it boasts the same processor as the 17 Pro, making for a phone that's a breeze to use. Right now, Optus has slashed AU$500.40 from the RRP of the iPhone Air on all plans.

Total cost over 24 months is AU$2,618.16

Samsung Galaxy S25 Ultra (256GB) | 50GB data | 36 months | AU$114.68p/m + free Samsung 65-inch TV

The Galaxy S25 Ultra is arguably the best best Android phone available right now, and right now Optus is throwing in a free 65-inch Samsung 4K QLED TV worth AU$1,499 with the device. I've selected the Small Choice plan once again, and over 36 months this time, but you'll get the TV no matter the duration you opt for.

Total cost over 36 months is AU$4,128.48

iPhone 16e (128GB) | 50GB data | 24 months | 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, the iPhone 16e is the obvious pick for anyone wanting an affordable iPhone. It benefits from Apple Intelligence features and a highly capable camera.

Total cost over 24 months is AU$2,318.64

Samsung Galaxy A56 (128GB) | 50GB data | 24 months | AU$84.10 p/m

While it's possible to get the A36 for just AU$5p/m before plan fees, we've had to select the A56 for its its excellent value. In fact, we consider it to be the best cheap phone you can buy. 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$2,018.40

iPhone 17 Pro (256GB) | 50GB Data | 24 Months | AU$138.28p/m

If you've got the cash to splash and you want the best iPhone of the moment, look no further than the 17 Pro. Ushering in an all-new design, powerful cameras and AI smarts, it's all the phone you could ever need. Note that we've selected the base 256GB storage model and set it to a 24-month contract, your monthly price will change if you change these variables.

Total cost over 24 months is AU$3,318.72

Samsung Galaxy S25 Ultra (256GB) | 50GB data | 36 months | AU$114.68p/m + free Samsung 65-inch TV

The Galaxy S25 Ultra is arguably the best best Android phone available right now, and right now Optus is throwing in a free 65-inch Samsung 4K QLED TV worth AU$1,499 with the device. I've selected the Small Choice plan once again, and over 36 months this time, but you'll get the TV no matter the duration you opt for.

Total cost over 36 months is AU$4,128.48

Samsung Galaxy Z Flip 7 (256GB) | 50GB Data | 24 Months | AU$129.94

If you want to go down the flip phone route, the Galaxy Z Flip 7 is an obvious choice. I have seen this phone and plan combo cost much less in the past, so I would recommend looking into other providers or holding out for sales if you know it's the phone for you. Alternatively, you can could buy it outright and pair it with a SIM plan, or get the Fold 7 with a free Samsung TV at Optus for a limited time.

Total cost over 24 months: AU$3,118.56
