Picking a cheap plan is no different to picking a high cost one, although you do have to hunt around to make the most of your meagre spend. Many plans with great inclusions at this budget are prepaid, meaning you'll never have to pay excess usage fees.

How to choose a cheap mobile plan

Picking a cheap mobile plan is finding a balance between what you absolutely need and what you can go without. Here are the top things to consider when you're browsing through cheap mobile plans.

  • Data. Data's the biggest contributor to cost for any mobile plan, so keeping it low can save you heaps. Just remember that if you're routinely going to break your limit, a cheap plan will end up being significantly more expensive and less worthwhile.
  • Consider MVNOs. Purchasing a plan with a big carrier like Telstra or Optus brings some brand security and neat features, but they usually won't be the cheapest choice. Instead, consider going with an MVNO that uses their networks for a more affordable option.
  • Extras. Cheap plans tend to pare down on the bonus features you get like free streaming or other goodies. These extras can be nice, but only if you're going to take advantage of them. Leave them out and save.
  • Downgrade your contract. Even if you're locked into a long-term phone contract, you might be able to save. Most providers will let you switch between a specific set of plans without breaking your contract, allowing you to downgrade to a cheaper one.
  • Watch billing periods. Some prepaid plans come with 28-day recharge periods, while others offer the full month. 28-day expiry periods will end up costing you at least an extra recharge fee per year.
  • Talk minutes. The cheapest mobile plans (usually under $10) can limit how many minutes of calls you can make, even within Australia. If chatting is important to you, steer clear.

Are prepaid or postpaid plans better if I want a cheaper deal?

While neither type of plan is inherently cheaper, you'll always know what you're paying with a prepaid plan since your service gets cut off when you hit your limit. Here's a quick rundown of how they compare.

What other options are there for cheap mobile plans?

Some of the cheapest possible plans are expressly designed for people who rarely use their phones or who just don't use much data at all. Many providers have long-expiry plans where you purchase a certain amount of credit and then are charged for each call you make, text you send or bit of data that you use.
