I was in Chicago three weeks ago and had 800 everywhere I went. Not once did I drop a call. Usually at my wife's uncle house I would get one to two bars inside and one bar to no service in the basement. With 800 I had three to four bars. I was impressed and happy. However, I was unable to get LTE inside the house. LTE on the street was considerably fast and consistent. I traveled all around Naperville, Woodridge, Bolingbrook, Lombard, Downers Grove and Wheaton.
