If you are a cellphone user, you have experienced "dead zones." The entire phenomena has been well-documented by horror movies, sit-coms, and even commercials. However, you can buy a cell phone signal booster for your building, home, or car, which will improve your signal's strength in that area. It need not be a so-called "dead zone," it can improve cellphone signal strength anywhere, with models starting at under $200.00.
You no longer have to do the "bar walk," hoping to find that special pocket where your phone can finally place a call. Just get a signal booster and use your mobile phone the way it was meant to be used!
