I'm looking in my G3 F400S's (Korean) hidden menu and confirming that it works with the following bands:
WCDMA: 800, 850, 900, AWS (?), 1900, 2100.
GSM: 850, 900, 1800, 1900.
LTE: 1, 2, 3, 4, 5, 7, 8, 17, 20, 28, 40.
Also would like to say for those with the Korean version...I've rooted mine and flashed the SphinX G3 Neo V2.0 ROM...and I must say that I'm more than happy!!!
I'm able to access all hidden features like LTE-Only, my "home" ain't in Korea anymore, the default weather app is now Accuweather...and many other stuff that I preffer.
So concluding...root, install SphinX ( there's also the VDT V8 Full, but I find it too difficult to install and gave up) and install the G3 Tweaksbox from Google Play (you'll be able to modify many features from your ROM).
That's it guys...Have fun!

Hey mikeythedude...I don't know why, but I tried my F400S with AT&T in NY and only got 3G...no 4G or LTE...just for you guys who are asking to know.
