Prepaid phone plans often get a bad rap, which isn’t really fair. There’s a common assumption that they’re worse value, but if you’re looking for a new SIM-only plan and not considering prepaid, you’re missing out.

Prepaid inclusions tend to match postpaid plans these days, meaning they have plenty of data. They’re contract free, so you can swap provider or move to a better deal whenever you want. And best of all, prepaid plans are fool-proof. Since they have a hard cap, you can’t get caught unaware by excess fees. This is perfect if you’re on a fixed budget you want to stick to.

Prepaid plans under $20

If you’re looking for pure bang for buck, TPG is a clear winner when it comes to prepaid. Its $19.99 recharge gets you 4GB per month with unlimited talk and text. You’ll have to pay a $10 setup fee, but this is made a little bit more palatable by the fact you’ll get 50% off the plan for your first six months. $10 for 4GB is a bonkers, given that a $10 prepaid plan typically gets you 1GB. TPG is powered by the Vodafone 4G network.

If you don’t want to go with TPG, Kogan Mobile is a close runner up: you’ll get 3GB for $16.90 on a 30-day recharge with no setup fees. Kogan Mobile is also powered by the Vodafone 4G network.

Prepaid plans under $35

TPG’s aggressive discounts make it another solid contender in the under $35 per recharge category. While you’d normally pay $34.99 for 15GB and unlimited talk and text, new customers get their first six months for $19.99.

If you want more than one service on the same bill, you might want to consider Yomojo thanks to its family bundling. The more plans you have on your account, the more you’ll save. For example, bundling four services will knock 10% off your total bill. Yomojo is powered by the Optus 4G network.

Prepaid plans under $50

Opting for a prepaid plan doesn’t mean skimping on inclusions; if you’re okay with spending a little more, you can get a prepaid plan with a hefty amount of data.

Boost Mobile is one of the best options for a big data prepaid plan, offering 30GB on its $50 recharge. This also includes data rollover, and data-free access to Apple Music. Better yet, Boost is powered by the Telstra network.

And I’m going to sound like a broken record, but the TPG deal is once again worth calling out. $39.99 per month gets you 20GB, but new customers get a discounted rate of $24.99 per month for their first six-months.
