we recently moved from the San Francisco bay area to aurora, Colorado. we have notice a significate drop in cellular range even though there is a large cell tower less than a mile from us. do you guys come out to do range checks? our zip code is 80016 cell tower is at corner near smoky hill rd and e-470. people we have met since moving here said Verizon range used to be great until about 1 1/2 years ago then it sharply dropped off.
