Cell phone signal boosters

wilson-cell-boosterI live in Karachi. I use the cellphone service offered by Telenor Pakistan. It is distasteful to say, but I will have to say that their signal is very weak in my area. Despite my repeated requests and complaint, they have done nothing to redress my grievance. I requested them to install a cell booster in my home. They curtly replied that they do not offer such a device to enhance signal in Pakistan.  My brother-in-law told me that a range of cell boosters are available in U.S. and Canada. These boosters enhance signal strength.  He said that TerraWave and Wilson boosters are used in Canada.
