Ditto what others are saying. Sprints 4g lte is slow. My neighbor has them. I get faster speeds on tmobiles non lte network. Whats funny is he gets 4g at his work but said 4g stops at my house and he only gets 3g at his house. lol I would look into tmobile as well but make sure to check out different sites for coverage and tower locations. They can be good or bad in areas. Cant beat them where I live.
I would stick with verizon before I would ever switch to sprint.
