What you need before you begin
Before you start the sign-up process, gather the following:

- A Wi-Fi connection for the initial setup steps.
- Your device software must be up to date. Check for the latest operating system version before proceeding.
Activate a new Boost Mobile device
Boost’s setup page covers both iPhone and Android during device upgrades. For a new iPhone or Android device, Boost’s upgrade flow says to power on the phone, connect to Wi‑Fi, and update to the latest software before continuing.
iPhone activation
On iPhone, Boost says to follow the on-screen setup, but select SKIP for prompts about transferring cellular settings or setting up eSIM because that is handled in the Boost Mobile app.
Android activation
After updating your software, proceed with the on-screen setup. The Boost Mobile app will guide you through the remaining steps.
Bring your own phone (BYOD) to Boost Mobile
For Android BYOD activation, Boost specifically says the Boost Config App is needed to update device settings. This app ensures your phone is properly configured for Boost Mobile services. Once installed, open the Boost Mobile app and follow this path: Settings → Device Setup → Manage under the appropriate line → Change Phone. In the Boost Mobile app, tap Settings → Device Setup → Manage under the appropriate line → Change Phone. This flow handles the device setup for your existing phone.
