"SOMETHING SCREWY IS GOING ON HERE!"
Yes, yes there is.
You have created a very confusing post.
First you state:
"3GB OF UPLOAD DATA USED WHILE DOING NOTHING"
Nothing that you know of. Then you go on to post:
"HOW CAN A 200MB VIDEO DOWNLOAD REGISTER AS 3 GB OF DATA DOWNLOAD"
So .... which is it ... upload or download? That makes a major difference as to root cause.
You go on to say: "ON MY IPHONE"
That implies that at least a portion of your network is wireless but you fail to describe your network, your platform, plan level and Modem is use and if you are using your own wireless router or the wireless portion of the HughesNet HT2000w Modem.
You go on to ask:
"CAN I HAVE A DETAILED LISTING OF ALL DATA I USE FOR A 24 HOUR PERIOD"
Hughes provides you with three "usage" meters and two "history" displays. These will show total usage but not usage per device nor sites/IP addresses accessed.
Hughes, as your ISP, makes a volume of data available to you. How you "spend" that data allowance is your choice and it is your responsibility to manage your network.
Computers and other networked devices have both programs and applications that you can see running .... they also have many background processes that access your connection and use data without being easily seen.
The "structure" of your post would seem to indicate a lack of solid foundation of understanding of computers and networking.
The easiest solution would be to obtain a personal Router that has the ability to break out data usage per device.
If you are using the HT2000w wirless modem this would entail turning off all the Modems wireless channels and use those of your personal Router.
I use an Asus RT-AC3100 Router that provides a very detailed Traffic Analyzer function.
Here are a couple of views:
Usage per device over a three day defined period:
A statistics view showing hours of usage of all devices:
A breakout of the hours of usage of a single device and the applications/processes that were active as well as the IP's accessed:
In the end, managing your devices and your network is YOUR responsibility.
