Optus SIM Only Phone Plans


If you’ve just come out of a lengthy phone contract or you’re just looking for the next best deal, a SIM only plan may be a great way to save some money and get access to a plan that packs a punch. Optus provides a selection of postpaid month-to-month plans as well as the option to build your own plan. If you’re looking for a new phone plan but don’t want a new smartphone, an Optus SIM only deal could be the right deal for you.

A SIM only plan means you bring your own phone and the telco you go with provides a SIM card, so you can simply pop in your SIM card and you’re good to go. This makes it possible to use an older device or buy your phone outright, which could work out cheaper in the long run. You can also do this with a prepaid phone plan, of which Optus has several different options, but in this article we’ll focus on postpaid plans. Read on to see what Optus has to offer when it comes to SIM-only plans and how they compare to other telcos.

SIM-only postpaid plans from other telcos

Before we take a look at what Optus is offering on its postpaid SIM-only plans, there are plenty of other telcos fighting it out for your business. So, how much data can you get for your money?

Optus Sim Card

Optus has a few different postpaid SIM only plans on offer. Keep an eye out for things like bonus data, data-free Optus Sport streaming and more, although these extras are usually offered when you pay a bit more.

Optus’ postpaid plans also come with unlimited data, speed-capped at 1.5Mbps, if you surpass your monthly data limit.

There’s a lot to say about Optus, so let’s see what it offers below.

Optus Month-to-Month SIM Only Plans

If you don’t mind sticking around for a while, then Optus rewards its customers with decent data inclusions for a reasonable price. Not only do you have a choice of four postpaid plans, you can also build your own postpaid plans with your choice of data allowance and international inclusions. Some plans include international calls and global roaming data, and most plans include data-free access and a subscription to Optus Sport.

The option to build your own plan is a good option if you want to customise your data choice but don’t need international call extras, or perhaps you need global roaming inclusions but don’t need that much monthly data — the choice is yours. The below table includes the four Optus postpaid plans as published on Canstar Blue’s database, listed in order of cost from lowest to highest.

Is an Optus SIM Only plan worth the money?

Optus has a handful of SIM only plans to satisfy most budgets and needs. However, the question is, can you find a better deal elsewhere? While the answer may be yes, especially if you’re after a super-cheap plan, it’s not always so simple. Optus often includes bonuses such as data-free Optus Sport, which could be enough extra value to make the price worth it. Overall, Optus has a series of fairly competitive plans in the SIM only space, but if you’re after the most data you can get at cheaper prices, several other providers are also worth a look.
