It will boost a great deal but can not get service whereas not there.
Sorry, there was a problem. Please try again later.This is an excellent unit but it can only boost signal if present so if you don't have any signal at your location you are SOL. Stand on top of your truck running board and hold your phone 2 feet above your side mirror. if you have one bar this unit will help. if none it wont. Overall I get one to two bars of signal boost.
