Hi, cindyl9561. Please enter the Device ID here https://activate.boostmobile.com/bring-your-phone?intnav=TopNav:Phones:BringYourPhone or visit a Boost Mobile store to check if your phone is eligible. You'll need to purchase a new SIM card when you Bring Your Own Phone from a non-Boost Mobile wireless provider. Your new Boost Mobile SIM card will allow you to use the Boost Mobile network. To get a Boost Mobile SIM card kit, buy online, visit a Boost Mobile store or contact your local Walmart for product availability.
