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?

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.

- 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.
