Just bought this device last Sunday and Verizon says I have used over 3G's of my 5g allowance. Anyone else have this problem? I have not streamed any video or radio. I have left device on but was told by Verizon to shut it off when not in use and it is using data when I am not on computer. No DSL is available in my area and I have an autistic son who uses the computer after school and on weekends. I have been on the computer for most of the day. I don't understand how I could have used 3.142G in 5 days. HELP!!! At this rate my internet bill will be out of this world.
