So I received the 4g LTE signal bosster and proceeded to start it up in my window which gets 1 or 2 bars with my phone. It didn't work. Called it in, they said it was defective sent me a new one. Still didn't work. Called it in again. Got someone better than the signal booster experts that could tell me that the booster doesn't support the 700mhz frequency or band 12, which is all I can get at my home, and only outside. Cel fi has a booster that supports 2 4 and 12 for tmobile, says so on they're webpage. It's called the duo+. When will TMobile make this or one that supports my frequency available?
