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:

  • 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.
