Dash).? My T-Mobile signal is between zero and two bars inside my apartment. It is five bars when I step outside. I would like to get that kind of reception inside, you know, during those chilly winter days.

Is this worth trying?

T-mobile has terrible service. I ended up switching as soon as the contract was up.
