I live in the Los Angeles area and Sprint/Boost works for me. Maybe in a outlying area it might not be the best choice. You would have to check.
I also have a Virgin pay as u go Phone here in Hollywood if the need arises, which has top-notch CS. The phones are cheap that if u lose them, it’s only $10...and boy, I;ve lost a lot of cellphones throughout the years.
Metro PCS that my buddy pays for $40 unlimited everything, he swears by it instead of using Boost $60 unlimited.
