Sorry, but you alls signal towers SUCK!! I have metro by tmobile which uses your towers, & my signal has been going on & off for days now!! First it's in LTE mode, then it goes to H+ or G with 3 bars!! I don't know what you all are doing, but you all are not what you claim to be when you advertise it on tv!! I have tried everything from resetting everything, to factory resetting & it still does it & then i have dropped calls!! I live in kissimmee, fl, & the signal sucks everywhere, even outside
