Romeo - Spotty. In the places where it worked internet was slow enough I only used it for email. Sean F. - Worked fine most of the time, but can be patchy at various times of the day.
Terry - Wasn't much good for voice, but texting worked fine. Chris - Data was spotty. Voice and text worked fine.
Felix - According to Sprint's map, Mandeville is a dead zone.
