What do you guys recommend for boosting cell signal when you don't have access to the modem. I live in a shared house in the basement and its starting to get hard to use truphone. I do have google voice but the wifi isn't the most reliable. Also hoping I don't need to change carriers because I do love my current (Google Voice + Truphone + FreedomPopRedPocket) setup. Primary provider is ATT towers. Any and all help is greatly appreciated.
Caveat: this may or may not be adaptable to your situation. I use a straight talk home home phone device, which allows me to unscrew the included antenna when necessary and screw in a wire leading to an external ( about 9$) magnetic stick antenna which I locate in an area with good signal. The antenna is tuned to my carriers frequencies(always supposing my base station supports those frequencies) via wire for better reception
