Hi, Bcash90. Please go to https://activate.boostmobile.com/bring-your-phone?intnav=TopNavhones:BringYourPhone to check if the device is compatible. If it is,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, Best Buy, or Target for product availability.
Understood. It it is someone selling it, you can ask for the IMEI/ DEC to verify if it is compatible.
