My family has had poor cell quality at home ever since we moved 11 years ago and I'm hoping for some suggestions. We get 0-1 bars of service throughout the house. We live in a NW suburb of Chicago, so one would expect better coverage from the "#1 coverage provider." I am looking for a low/no cost option to increase cellular quality as we already spend more than enough for the 5 of us on our plan. Does anyone have any suggestions of things that have worked?
