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 only uses 12.8GB 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.
