We have really spotty coverage here at the house even though we are 1.3 miles from a T-Mobile store - and the iPhone 4 cannot get a single bar. The 4s gets about 1 bar here and there and the HTC gets 2 bars here and there.
I ordered a refurbished Cel-Fi RS1 that is branded T-Mobile on it and put the Window Unit in the attic where it does get 3 bars. The Receiver Unit I put in the kitchen two floors below. It lights up green on distance and 8 on signal strength. All looks good.
None of the phones seem to pick it up - they do not see any improvement in service quality. What am I doing wrong? Will this just not work?
