My phone works just fine, I have metro
I have T-Mobile however my girlfriend does have Sprint l and she said that it most likely depends on your phone because she has full bars but yet her service run slow.. however you do not need to worry about the 4G LTE service by Sprint because there is free Wi-Fi available for all its members and I use it as well no matter where in the gym I am I get good connection where I stream my music constantly. I hope this reply helps you.
