Meet the Cel-Fi GO X: a cell phone signal booster that helps reduce dropped calls and improve speed in your home. It is a 100dB cellular signal booster that works for AT&T, Verizon, and T-Mobile devices. Its Cel-Fi Wave app lets you easily monitor everything on your iOS or Android device.
The GO X may amplify one cell carrier at a time but delivers more of a boost than comparable models. Its app has an antenna position test to help you find the best location for the outdoor antenna.
