A booster doesn’t create cell signal. It picks up the outside cell signal (no matter how weak) and amplifies it inside your home for better talk, text, and data. The effectiveness of any booster depends on the strength of the outside cell signal.
Sorry, there was a problem. Please try again later.Could try one of these cell signal boosters with antenna on roof but first I would try getting on roof to check if you get any signal bar(s) on your cell phone. If get signal then may amplify with cell signal booster. Best wishes.
