    So I used my AT&T sim in a Verizon Galaxy S4 and I keep getting the message Sim Card is from an unknown source and can't clear it. The only thing I can do is get to "app info" which takes me to setup wizard which I don't think can be uninstalled on a non rooted device. I also only get HSPA+. Does anyone have settings where they're getting lte?
