Optus has dedicated business mobile solutions for up to 300 plans, but the main focus of this page is plans reviews for smaller businesses. Enterprise customers with more than 300 employees in need of phone plans can alternatively contact Optus Enterprise for support. While Optus tailors mobile plan solutions for between one and five employees or six to 300 staff, smaller businesses can take advantage of the value and savings found in Optus mobile plans built for everyday users.

Quick verdict

Optus may not have as wide-reaching network as Telstra (for 4G and, particularly, 5G), but it’s still got coverage in most parts of Australia. Basically, if you business operates in any populous part of Australia, you shouldn’t have any issues with an Optus mobile plan. Optus has good dollar-to-data value on its plans, with plenty of data and decent inclusions. It’s a shame there aren’t cheaper SIM Only plans and 1.5Mbps post-max-speed throttling isn’t ideal, but there aren’t any excess data charges.

Optus business mobile value for money

No cheap plans, but plenty of data from mid-tier upwards.

We advise small businesses to use SIM Only plans over Prepaid plans, unless you use a phone more reactively and don’t have on-the-go data needs. If that’s you, long-expiry Prepaid plans are worth considering to help keep costs down.

Note that all Optus SIM Only plans include access to the Optus 5G network (where available). Similarly, Optus SIM Only plans let users share data on eligible plans under a single account, which is a good choice for small business users. Optus SIM Only plans start with the $49 Optus Choice Plus Plan, which comes with 30GB of data.

There’s money to be saved if you go with an Optus MVNO or Vodafone MVNO, but you’ll have to pay closer to this particular Optus plan price if you want partial Telstra 5G or Vodafone 5Gaccess. Below are some of the most popular SIM Only plans from our database with at least 30GB of data.

The dollar-to-data value increases dramatically with the next Optus plan. For not a lot more per month, the $59 Optus Choice Plus Plan comes with 100GB of data, plus unlimited calls and text messages (no MMS) to 35 selected dialling destinations.

That 70GB jump in data thins out the SIM Only competition. There are other competing telcos on the Optus, Telstra wholesale and Vodafone network with better pricing and/or more data, but international call inclusions and data sharing are rarer perks. For comparison, below is a daily updating list of SIM Only plans from our database with at least 100GB of monthly data.

The next cheapest plan is the $69 Optus Choice Plan, which has 220GB of data and the same international inclusions. Again, Optus continues the trend of paying not a lot more for a whole lot of data.

Competition is a lot thinner when you start dealing with 200GB of data. There are alternatives on the Optus 5G and Vodafone 5G network at this price point, which are worth considering if you need more than 200GB of data. Below is a daily updating list of popular SIM Only plans from our database with at least 200GB of data.

The penultimate SIM Only plan is the $89 Optus Choice Plus Plan, which ordinarily comes with 360GB of data for use on the Optus 5G network. Optus is currently running a promotion that bumps that figure up to 500GB, so the amount of bulk value here blows away most of the competition.

There’s only one other plan in our comparison engine that competes with 400GB+ of data, and that’s the $85 SIM Only Ultra+ Plan from Vodafone, which comes with unlimited max-speed data on the Vodafone 5G network. Check out these two plans side-by-side below.

Optus Business Mobile Plus

If you’d prefer a dedicated Optus business plan, consider Optus Business Mobile Plus. This plan structure supports between one and 10 SIMs. There’s a 10% discount for two sims, 20% for three, 26% discount for four to seven SIMs, and a 30% discount for eight to 10. The plan starts at $55 for 80GB of data, and every SIM added boosts the shareable data pool by 80GB. Like personal Optus SIM Only plans, Optus Business Mobile Plus plans come with Optus 5G access, no excess data charges (1.5Mbps throttling after data cap) as well as unlimited calls and SMS to 35 selected destinations.

Optus business mobile features and perks

Not too many business-specific perks, but there are a couple of great inclusions.

All Optus SIM Only and Prepaid plans come with unlimited calls and text messages (SMS and MMS) to Australian numbers. For Optus Prepaid monthly plans, you can roll over up to 200GB of data and up to 84 days if you recharge early. Not every Optus Prepaid plan includes Optus 5G network access, but all Optus SIM Only plans do. Optus SIM Only plans also include data sharing under a single account for eligible plans.

Except for the cheapest Optus SIM Only plan, all other options come with unlimited calls and SMS to 35 selected dialling destinations, which includes:

  • Brazil
  • Brunei
  • Cambodia
  • Canada
  • China (mainland)
  • Colombia
  • Denmark
  • France
  • Germany
  • Greece
  • Hong Kong
  • Hungary
  • India
  • Indonesia
  • Ireland
  • Israel
  • Italy
  • Japan
  • Laos
  • Lebanon
  • Malaysia
  • Malta
  • Mexico
  • New Zealand
  • Norway
  • Poland
  • Romania
  • Singapore
  • South Korea
  • Sweden
  • Taiwan
  • Thailand
  • United Kingdom
  • United States of America
  • Vietnam

There aren’t any excess data charges for Optus SIM Only plans, but the trade-off is a sluggish 1.5Mbps connection speed for the duration of your billing month.

What is Optus?

Optus is one of three main telecommunications providers in Australia, which offers mobile and broadband internet services. Its mobile network has the second largest reach (behind Telstra but ahead of Vodafone) and supports 5G, 4G and 3G cellular connectivity.

Optus business mobile support

Plenty of support options, including dedicated business support channels.

We understand that one person’s support experience with a telco may differ from another’s, which is why we look to quantitative support pathways. Optus offers a wide range of support via telephone, online chat, social media, self-paced online support, as well as brick-and-mortar stores for in-person support.

Optus also has dedicated business support options for authorised representatives. Chat with Optus business support via online messaging service or call them on 133 343, Monday to Friday 8:00am to 7:00pm AEST or Sat and Sunday 8:00am to 6:00pm.

How we review mobile providers

Whether we’re evaluating personal or business mobile plans from telcos, we follow the same approach. It starts with dollar-to-data value for money. Telcos that receive high scores tend to offer more gigabytes than the cost of a plan.

Still, network coverage is also a key consideration, which is why the Telstra and Telstra wholesale networks rank favourably with us as they’re the largest. Optus and Vodafone aren’t too far behind, admittedly, but the Telstra 5G network has a clear lead over Optus which, in turn, is ahead of Vodafone.

We like to see mobile plans with meaningful inclusions, be they access to additional services or more practical features like data sharing and no excess data charges. In terms of support, we tally the number of support pathways a telco offers and use that as a guide to how much a telco has invested in helping customers with issues. For personal mobile plans, we may also take publicly available customer reviews into account.

Optus business mobile FAQs

Optus Sport used to be included with Optus SIM Only plans, but now it’s a separate subscription. Sign up for Optus Sport via the Optus SubHub for $6.99 per month.


You can visit an Optus store or order a phone via the Optus website. Alternatively, use our comparison engine to select a specific phone or see a range of handset options available from Optus.

It really depends on what you’re after. Telstra business mobile plans may offer faster speeds via the widespread Telstra 5G network. Optus business mobile plans have better dollar-to-data value, but the Optus 5G network isn’t as far-reaching as Telstra’s.
