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 that’s a different story. My main motive is to find out how to overcome cell phone reception problems at my home. And how much does it cost for a cell phone reception booster?
