I am having issues going over on data usage. The times do not match up and it is showing majority of it is Communication & Device services. My wife and I just switched to Verizon on Friday and by Saturday night were getting messages about being 50% to our limit. We are set with the 1GB plan since we never went beyond that with our other provider. We also know we have a smaller plan and have been ensuring we are almost always on Wifi? It appears that the wifi and Data are being consumed Simultaneously.
