Sometimes, all it takes to earn the people's vote is a timely discount or an unlucky misstep by the competition.

To compare phone plans, it’s worth understanding the three different types available to Australian consumers. All three should let you keep your number as you switch between telcos, but some are going to be a better fit for your needs than others.

Postpaid mobile plans range from cheap to expensive and bundle a monthly plan with a handset. This is a straightforward way to pay off a new smartphone without having to think about pairing a new handset with a SIM Only or Postpaid plan. Regardless of whether it has 5G or not, handsets tend to be offered as interest-free monthly repayment terms of either 24 months or 36 months.

SIM Only and Prepaid plans assume you already have a phone. Either you need an unlocked handset or you’ll have to stick with the carrier network that your phone is currently locked to. SIM Only plans are identical to Postpaid plans in terms of data, coverage and inclusions, minus the additional cost of handset repayments, which makes them cheaper overall.

Prepaid plans are paid in advance of a month, instead of afterwards like Postpaid and SIM Only plans (except for Telstra Upfront plans, which are paid ahead of usage). The duration of Prepaid plans varies from one day to a full year, but a month is typically broken down into 30 days, 28 days or, rarely, an actual month. Prepaid plans tend to have fewer bells and whistles than Postpaid and SIM Only plans but are a great way to stay in control of monthly costs.

In order to pick the best phone plan in Australia, you need to factor in not just the type of plan but also what it includes and whether the network involved can meet your individual connectivity needs. These days, the best mobile plans offer more than just data and calls. They also incorporate things like data banking, excess-free data, international calls and the ability to save by bundling or family plans.
