Optus Prepaid $15 SIM

Optus is Australia’s second largest mobile phone service provider and for a good reason. Despite facing stiff competition, Optus has made enormous investments in the reach of its phone network across the country, and now can boast widespread coverage to the majority of the Australian population, as well as impressively fast network speeds on its 4G Plus and 5G network.

Optus mobile quick facts

• The Optus network covers 98.5% of the population and the Optus team continues to rollout its next generation 5G network.
• Optus supports WiFi Calling, allowing you to use a local WiFi network to make phone calls. This is great in areas where coverage is patchy.
• Optus also supports Voice Over LTE (or VoLTE) which places calls over the 4G network and lets you use the internet at 4G speeds while you are on a phone call.
• Optus customers can make HD Voice calls with a compatible smartphone. These calls are much clearer than standard voice calls.
• Optus often has one of the best ranges of new phones available, usually in excess of 20 models to choose from including Apple, Samsung, Google and OPPO devices.

Optus mobile plans

Optus plans are customisable and flexible.

• You first have a choice between either a contract-free month-to-month SIM-only plan, where you select the one which best suits your data allowance needs or the best priced plan for your budget.
• Then you can add a new handset to your plan or opt to bring your own phone for less cost.
• If you decide you want a new phone, you can choose to pay it off over 12, 24, or 36 months.
• Optus also has a wide range of prepaid plans available on both short term and long expiry plans.

Data sharing

If you have multiple Optus Choice Plus month-to-month SIM-only plans on the same account, you can share all of the data from these plans together across services. This is great for families who might have a single high-data plan and several lower cost plans sharing the data pool. It is also ideal if you use multiple internet devices, like phones, tablets, or portable modems.

International phone calls

Optus is one of the more generous providers for anyone who needs international phone calls as part of their phone plan. Most Optus phone plans include at unlimited standard international Talk and Text from Australia to 35 destinations worldwide.

Endless data

Optus offers unlimited data at capped speeds of 1.5Mbps to ensure you don't get overcharged when you reach your limit. Unlike the other telcos, Optus has a few other options for the data-hungry — you can add a $6 unlimited data add-on which gives you unlimited mobile data on the entire 4G and 5G network for 24 hours, or you can simply top up your data for the remainder of the month for a nominal fee.

International roaming

If you have an Optus SIM-only plan, you can enjoy the telco's international roaming option without changing SIMs. For just $5 per day you'll get 5GB of data and unlimited standard Talk and Text in over 100 Zone 1 destinations. For context, Zone 1 includes large parts of Asia Pacific, North America, and Europe.

Optus SubHub discounts

Optus customers can leverage Optus SubHub to bundle their streaming subscriptions for a discounted rate. Enjoy up to 10% off your total streaming bill each month when you combine three or more eligible services together.
