Cell phones are in fact just an advanced version of the old walkie-talkies we all came to love as kids and are not always going to have 100% perfect reception. And, when the cell phone salesman at the local dealer is about to close his sale the last thing he is going to do is wreck it by telling you that the local mall is a dead zone! (an area where cell phone has poor or no reception)

The worst case scenario is after you’ve signed a one or two year contract, you then go home, or to your office or on vacation only to discover the new service plan you’ve just signed is worthless because you have no coverage.Unfortunately, you realize too late that most of the places you make your calls from are dead zones, so much for the carrier coverage map. A good tip is to always try out a friend’s phone in the places where you talk the most!
