A:AnswerYES u can use on the Boost network. Someone answered u can't use it with a prepaid service.... I call BullShyt, BOOST LITERALLY IS SPRINT and vise versa. I speak from experience, purchased an iPhone 8 Plus factory set for Sprint and "locked". I then walked into the closest Boost location and the rep plugged it into his laptop and 20 mins later I was walking out the door Boost service active and awesome. Honestly just contact a Boost bud u feel u can trust and see what they advise. It would suck to have wasted the money and it not work out. I have had a past experience when I started with iPhone 6 and kept getting a NO u can't (like every other response here) every Boost rep I called simply due to the fact that none of which knew how to do it. If u run into the same issue insist on speaking with the actual store manager before trying the next Boost location. When I got to one really good manager he also had me up n running in no time. I WISH U GOOD LUCK. SORRY SO LONG BUT TRYING 2 BE ACCURATE N INFORMATIVE .
