First and foremost, please have enough respect for your fellow users of this site to refrain from using foul language, whether it is bleeped out or not. It's immature and there is no need for it.
Now, there are many things on many devices that can use data without your knowledge, and none of them are the fault of HughesNet. For Windows based computers, the most recommended program for monitoring data usage is Glasswire, which monitors the data used on the computer it's installed on. It will tell you how much data was used, when it was used and just what program/app/service used it. It's free, and it's here... https://www.glasswire.com/
For non Windows devices there are similar programs, though I don't know what they are offhand.
If you have your HughesNet service connected to a DirecTV receiver it's best to disconnect it, as DirecTV receivers can use a LOT of data, even when they're off, and without any way to control it.
The following two threads may also help...
If you would like further help in determining what is using all of your data, please start a new topic in Tech Support, which you can do here...
Please keep in mind that it is mostly your fellow HughesNet subscribers who are going to help you with this issue.
And secondly, this area is for your opinion of this web site, not HughesNet service, as stated in the description before you clicked on it...
Wanna vent? Please find another appropriate outlet.
"Its sad hughesnet actually has to pay supporters"
I'm not paid by Hughes. I pay them for service and it works fine, within the inherent limitations of satellite internet, such as latency.
I respect your right to seek comfort in paranoid conspiracy theories, but this doesn't change the fact you're posting in the wrong area.
Want tech support to resolve your mysterious data disappearances? Post in tech support and work with the reps to figure out what's going on. It's very likely it's not elves, aliens, or the government using your data, but something connected to your network.
*I am not a Hughesnet employee or representative. This is a customer-to-customer tech support community, and I am a customer.
Paranoid conspiracies huh lol. One, you can search far and wide and not ONE person who has subscribed with this company except the few and i mean few guru's on here none the less have been satisfied with their service.
Haven't we had this discussion before? Ever hear of thing called confirmation bias? This is mostly a support site where people only post when they have technical problems, got something different than they expected, and/or prefer to whine instead of get something done about it. You never, if hardly ever see the real majority of people that don't have problems.
And, if you don't think those people exist as a majority (likely about 500-1000 for every whinger you see on here), then you don't understand the sheer cost involved, how return on investment works, and how HughesNet is able to launch new satellites and expand their system every couple of years.
And finally, just like the original poster, you're way off-topic for this area. If you don't have something to say about the Community (aka this web site), take it somewhere else.
Nothing you've posted in this forum has anything to do with this web site, only your continued diatribes on the service. This is not a good way to go about things. You're actually making a good case against yourself, since everything here is also on record. You portray yourself as being just a disgruntled customer with a vendetta. So, good luck with that.
Secondly, if you think you can do whatever you want just because you're a paying customer, suit yourself. This site has terms and conditions that you agree to in order to continue its use. Continue to violate them and expect to get booted off by an admin.
Thirdly, this has been going on for months with you. If you're that unhappy, why do you not just end your contract, which I'm certain is cheaper than continuing the service both monetarily and aggravation.
Also recommend you use the spell check feature. Your spelling and grammar do even less for your credibility.
Have a nice day.
