Hi RenoHuskerDu,
I see it's your first time posting here, so welcome to the community! I pulled up your account to review your case history and I'm glad to see our agents have provided you with complimentary data tokens. As the previous agent noted, you can follow our troubleshooting steps to first rule out that the unidentified data usage is coming from our end. Afterwards, it's a process of elimination to determine where the majority of your data is coming from.
Our community is made up of fellow HughesNet subscribers like yourself, and they've recommended GlassWire, a third-party data monitoring program to help you pinpoint the programs on your PC that use the most data. Feel free to ask the community for tips on using GlassWire.
There's also this thread with plenty of ideas as to what can use data without your knowledge and how to best manage your monthly data allowance.
