Because for the first twenty days of your service your monthly allowance reset daily, then changed to standard monthly resets. You need to download the Hughesnet Status Meter to remain cognizant of your usage.
The Status Meter is at the link below...
To add further, they do the twenty day daily resets to allow people new to the service to update and/or upgrade their computers and download other programs they would like or need in a way that doesn't impact their monthly allowance. It's done as a courtesy.
With your first month, after the resets, you ran out in eight days, just like it happened with your second month. If you have Windows 10 computers, there are things that need to be adjusted to be amenable to a capped service, so that they don't just continue to burn through data. Onedrive (the cloud), syncing, updates to other computers. Plus, changing Facebooks to NOT play vids automatically will help.
This is a part of one of my responses to a recent post. It may help....
If you have Windows 10 on the computers, you will want to make sure that they aren't using the cloud (OneDrive) and aren't syncing. To turn syncing off go to settings, accounts, then "sync your settings." The top option on that page should be to turn your sync settings on or off. Turn it off. As for the cloud (OneDrive), it may be on in your system tray. Right click it and go into the settings (I forget exactly what it says) and change it so it doesn't start on startup. I can't remember if there's anything else to change on it, but check anyway. Then exit out of it to turn it off for that time. It won't start again when your computer starts next time. The last thing with regard to the cloud is to go into settings, system, then storage. Make sure all of the save locations are somewhere on your computer, whether "This PC" or your C drive. Just make sure none of them say anything about the cloud.
Also, go into settings, then Update & Security. Click on Advanced Options, then Choose how updates are delivered. Turn off "updates from more than one place." That's another thing that will eat up some bandwidth.
Then make sure Facebook isn't set to play videos automatically.
Those few things alone will probably save you a lot of bandwidth.
This may or may not apply to you. If it does, it should help with saving some data. Those automatic, freely downloading/uploading things can use a LOT of data needlessly.
Tis why no one chooses Hughesnet if there is an "unlimited" service available. Hughesnet is an ISP of last resort, for people that have no other option. It's comparing apples to oranges. Two entirely different systems.
Unlimited plans with satellite internet are not an option due to the infrastructure involved.
It's not Hughesnet's job to advise you on how to use your computer, nor what settings to use. It's the consumer's job to decide what amount of data will be needed for his/her purposes.
If you feel you were misled by the sales rep, start a new post explaining so, and post the serial number located on the bottom of your modem. DO NOT post your SAN. Just the serial number from the modem. The reps can locate your account from the serial number, pull your sales call, and listen to what was said. They can then determine what to do from there.
