I am not able to get cell phone reception in my underground parking garage where I live. The strange thing is that the Property Manager has a signal with his phone. So on the internet, I saw that a company is advertising, that they can install a cell phone reception booster in the parking garage ,to be able to get a signal down there. Is this true or is it just a gimmick ? I sent an e mail asking the condo board if they could consider this for our garage .
