I've been on it all day, I have Sprint. (Chicago area) I know this means roaming, but it won't go off. My whole family has Sprint and are on Sprint's network, except me. Battery seems normal, LTE is fast... What towers does Sprint roam on? If it's still Verizon, I'll just leave it be (their LTE coverage is obviously better than Sprint's, so it's a benefit) but it must be a glitch or something because it won't go off extended.
