Simply go to Boost Mobile's website and add the iPhone SE to your cart. You'll automatically receive $100 off the iPhone SE. This discount is available for all colors and storage configurations.
All new and existing Boost Mobile customers are able to take advantage of this discount! The iPhone SE will just be locked to the Boost Mobile network, so you'll need an active plan to be able to use the phone.
This deal is applied automatically when you order the iPhone SE online.
