Prepaid SIM Card FAQs

What are prepaid SIMs?

With prepaid mobile phone plans, you pay for your services upfront, so you know exactly what you're spending - meaning no more nasty surprises at the end of the billing period!

Boost Mobile SIM only plans offer a wide range of affordable prepaid mobile SIM plans featuring services such as unlimited calls and texts, unlimited standard international calls, as well as substantial monthly data allowance.

Can I buy a SIM card and keep my number?

Yes, you can buy a new SIM and keep your number. Simply head to activate and click ‘keep existing number.’

How do I choose a good SIM card?

Boost Mobile offers a selection of SIMs, catering to everyone’s needs. Here are some tips to help you choose the best SIM for you:

Data: Think about your data needs. If you’re a Netflix junkie, go for a plan with plenty of gigs. If you're more of a casual user, a smaller plan might be just right.
Data rollover: Some of our plans let you rollover unused data to the next recharge.
Unlimited talk & text: All of our 28 day and long expiry plans include unlimited talk and text.
Network coverage: All of our plans are on the full Telstra mobile network, covering more than 99.4% of the population and more than 2.6 million square km of Australia.
Expiry: We have two great options to suit every type of user. Our 28-day prepaid mobile plans provide monthly flexibility without the pressure of a lock-in contract.

Our 365-day plans are perfect for those who want to set and forget.

Local plans:
