Recently having issues in numerous stores in and around the 53546 zip code. My background is in science, so I am aware the composition of the construction of the building can degrade signals, or create a faraday cage which can do the same. But considering the close proximity to a major interstate the data interruptions don't seem consistent with the quality of service I would normally expect from Verizon I'm utilizing an iphone 4s, and lately my data usage has been minimal as over the last few months, but days where I'm not on wifi I usually use between 100-300mb.
