It does not boost AT&T LTE signal at all, it does not even find it. All it does is 3g and 4g. My iPhone 6s gets 2 bars of LTE at the window where I setup this device. The Cel-Fi Pro only finds a 4g signal (the app shows it as 3g for some reason). I have tried moving it all over my upper floor without any difference. It does boost the 4g signal to 5 bars, but without LTE it is an expensive paperweight. I am sending it back as soon as I can get a RMA. Beware if you are thinking about getting one.
