If you purchased a device from the online Boostmobile store and you already have a Boost account, you can go to a Boost mobile store and ask them to do a device swap on your account. You may have to pay service fee so they can do it for you.
Hi Kjpoll09. Once you have a device, you can activate it online or in stores. You can complete an activation online by selecting the Activate button on the top right corner of our website.
