Are there products like mobile signal booster. A friend at work told me that he has just ordered one because he had heard good things about it. But I doubt their credibility. Do these things actually work and improve the signal quality. I doubt because if these things were around why didn’t I hear anything about them until now. But thats a different story. My main motive is to find out how good they are and if they work which is the good one to get. And how much does it cost for a cell phone reception booster?
