TERRIBLE! Service was fine for a couple weeks then the connection got so bad that people couldn't hear me and vice-versa; then the phone wouldn't accept my password (my guess because of the poor reception in the middle of Dallas!) and it LOCKED ME OUT over and over again until it was permanent and the Boost rep told me it was a problem with the iPhone 15 itself. After 1.5 hours of double- and triple-troubleshooting at the Apple store, they said the phone wasn't the problem. Of course, by now I'm past my 30-day return period and all Boost kept tell me was that the 30-day window to return had passed. BTW this is my first ever bad review for any business or product. To ID my # is: *******729 but, of course, it doesn't work.
