To switch Boost Mobile phones, open the Boost Mobile app on your new device, go to Settings → Device Setup → Manage under your line, and tap Change Phone. This app-based swap keeps your existing phone number and Boost Mobile services (Boost Mobile Plans, Payments and Account Services) active on the new device.
Before you switch Boost Mobile phones
Start by confirming you have your old physical SIM card. If your current phone uses a physical SIM, you can remove it and insert it into the new phone. If the original SIM card is missing, contact Boost Mobile Customer Care or visit a Boost Mobile store for a replacement.
Boost does not publish a model-by-model compatibility list or an online checker on its phone-swap page. The new phone must be compatible with Boost’s network; if you are unsure, contact Customer Care or a store before proceeding. Boost's retrieved support page does not give a supported-model list, a device-compatibility database, or a version floor for iPhone or Android on the phone-swap page.
If the old device used a physical SIM, that SIM can be moved into the new phone.
