If you're shopping for a new SIM or phone plan, there's a good chance you'll want to consider Optus. One of the biggest Australian telcos, alongside Telstra and Vodafone, Optus sits somewhere in the middle.

The telco offers a blend of Telstra's leading network coverage and Vodafone's affordable plans and regular deals, making it a compelling choice.

Furthermore, Optus' network regularly outperforms its peers and is regularly crowned Australia's fastest mobile network for both 5G and overall download speeds by OpenSignal. You can view how Optus fared against Telstra and Vodafone in the most recent OpenSignal report.

As with most telcos, Optus' best prices, deals and offers show up during major sales events such as Black Friday and EOFY. That's not to say there aren't any good deals throughout the rest of the year, either.

Optus also has some excellent SIM-only promos, with up to AU$120 in savings over 12 months on select plans in the first year.

If you're looking to pair one of the best phones or cheap phones with a SIM plan, Optus remains a strong contender. To help you navigate the options, we've gathered all the top deals and offerings on the most popular handsets and SIM plans below.

Noteworthy Optus deals

I'll get to the best Optus plans in a second. First, here are some deals currently available through Optus on some of the best phones right now.

Best Optus iPhone plans

iPhone 17 (256GB) | 60GB Data | 24 Months | AU$118.29 p/m

iPhone 17 (256GB) | 60GB Data | 24 Months | AU$118.29 p/m

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. Here I've paired it with the 60GB Small Choice Plus plan, where you'll pay AU$118.29 per month all-in.

Total cost over 24 months is AU$2,838.96

iPhone 17e (256GB) | 60GB Data | 24 Months | AU$101.61 p/m

iPhone 17e (256GB) | 60GB Data | 24 Months | AU$101.61 p/m

The iPhone 17e is another great-value model from Apple, benefiting from the latest A19 processor, which gives it improved camera capabilities over the 16e. It also gets MagSafe, which is a very welcome addition. If you want an iPhone but don't want to break the bank, there's no better choice.

Total cost over 24 months is AU$2,438.64

Best Optus Android plan

Samsung Galaxy S26 Ultra (256GB) | 60GB data | 24 months | AU$126.60 p/m

Samsung Galaxy S26 Ultra (256GB) | 60GB data | 24 months | AU$126.60 p/m

The Galaxy S26 Ultra is still one of the best Android phones on the market, with a new Privacy screen feature and Super Steady video being two feature highlights. There's no hiding it, this is quite an expensive option at Optus, even with the AU$600 device discount, but you're in for a treat with Samsung's flagship.

Total cost over 24 months is AU$3,038.40

Google Pixel 11 (256GB) | 60GB data | 24 months | AU$101.58 p/m

Google Pixel 11 (256GB) | 60GB data | 24 months | AU$101.58 p/m

If you're not too fussed about having the absolute top-tier specs, Optus has slashed AU$500 off the cost of the new Pixel 11, making it a better-value alternative to the S26 Ultra. While its Pro sibling has better cameras and a new HiLight notification LED, the base Google handset for this year also has the same 12GB of RAM and Tensor G6 chipset, making this the better value option.

Total cost over 24 months is AU$2,437.92
