Hmmm, model number on phone and in settings says C5502. My wife's C5502 also has the LTE option. Both bought brand new. I imagine it's just a common firmware and there's no way to enable LTE. In service menu the "working bands" only list UMTS bands but LTE is presented as an option in 4636 menu.
Is there a software way to check the radio chip on my phone?
