Cel-Fi Signal Boosters


    The T-Mobile Cel-Fi Signal Booster is a unique and simple solution that improves coverage within your home.


    Signal Boosters are available to those who have at least one bar of 3G or 4G signal in the home and have a T-Mobile phone or device that supports 3G or 4G. If you recently received a Signal Booster, make sure that you register it with us.


    Once you set up your Signal Booster, and your phone connects to the signal coming from the unit, the device functions exactly as if it were directly connected to a T-Mobile tower.
