Why we like it

We looked at mobile plans on the Optus network that cost under $30 a month. SpinTel came out on top. It won Best Value SIM Only Mobile Provider at the 2026 Finder Mobile Awards. Plus, you’ll save $48 over 6 months with its latest offer.

Pros

  • Even without discount, the ongoing price stacks up well against our $1 per GB benchmark.
  • The plan includes $50 worth of international call credit.
  • Option to sign up with an eSIM if you have a compatible handset.
  • You can use live chat to contact customer support if you don’t want to call.

Cons

  • The price will revert to $23 a month after 6 months.
  • 4G and 5G download speeds are capped at 150Mbps. However, this is more than enough for online activities on your phone such as streaming in HD.
  • You will be charged $10 per GB if you go over your data allowance. Once you hit 10GB, your data use will be blocked. You can disable this in your account settings.

How do you find the best mobile plan on the Optus network?

There are 3 key factors to consider when you're choosing a plan from either Optus itself or one of the smaller providers that use its network.

1. Price: Ask yourself how much you're willing to pay for your phone plan. Seek out sign up deals that are quite common in the telco space.

2. Data: Figure out how much data you use or need by either checking your phone, bill from your mobile provider or its app, or by using our data usage calculator. Oftentimes we pay for data we don't use. According to the Australian Competition and Consumer Commission, the average Aussie uses 14.5GB of data per month.

3. Inclusions: You'll want to choose a plan that best fits your feature requirements, whether it's the option of data rollover, international calls, an app to manage your plan or having roaming available for when you travel overseas. Or keep it simple and opt for a basic plan with calls, texts and data.
