I used it with T-Mobile. I had low signal outside my home but none inside.
Placed the repeater in my den and could make calls fine.
Removed it when T-Mobile adjusted the tower for more signal in my area.
Note: As it says in the documentation it does not make signal, it pulls the signal it finds outside to inside.
