No Cell Phone Signal

Nothing is worse than living in an area, owning a cell phone, and not having good reception. That's how it is at my house. It can get irritating at times, so I am looking into a wireless booster. A friend of mine swears by them, so I figure it's worth a shot. I can't imagine being able to pick up my cell phone and use it anytime I want. If this booster happens to work, I am highly considering cancelling my land line phone service. What's the point in paying two telephone bills, when you can use a phone that you can take with you wherever you go. Right?
