Service has dropped significantly in the past 6 months. There have been several new building put up and it seems Verizon is not keeping up with the transmissions for several new installs in business. I have 0 to 1 bar and the dbm is between -101 and -140 with the asu as low as 1 and normally at 99. I get no in-coming calls, if it dose happen to make in, it is dropped. I am also unable to make any out going calls. I have a Samsung S6 and it works beautifully in the other zip codes. My husband has the same issue and he has a S7, both phones are upgraded regularly as upgrades come out. I don't feel as if I need/should have to purchase a booster when Verizon should be able to keep up with the community.
