Signal booster overview

The 4G LTE Signal Booster takes low signal in your home (minimum of 1 bar 3G, 4G, or 4G LTE) and boosts it, giving you a stronger and more reliable signal where you need it most.

The device includes a window unit, which receives T-Mobile signal, and a separate coverage unit, which rebroadcasts it and boosts it in your home. You can usually set it up in 15 minutes.



  • Minimum of 1 bar of indoor T-Mobile signal in your home with 3G, 4G, or 4G LTE (Not for 2G signal)
  • Phone that can connect to the T-Mobile network's 3G, 4G, or 4G LTE
