Hello all! I've been trying to get T-Mobile's LTE working on my Z1 but my attempt have all failed. My device is running unrooted and unflashed if it helps. All I've gotten to connect to is 4G at the moment. I live in NYC so I'm well assured there's LTE in my area. Any help is appreciated!
Admittedly, I'm slightly irritated from spending quite a bit of time on the phone and getting no where. I know this device supports LTE since I can select LTE as an option when I go into *#*#4636#*#* and phone info
That doesn't make sense, the phone does support T-mobile USA, have you check the XDA forum, I've seen users with the same issue but they were able to get it to work, I don't have this phone so I can't give you any more info on this.
Excellent
