Firstly, this section is concerning this Community, not HughesNet's service.
Secondly, if you would like help with figuring out what is using your data so quickly, please start a new topic in Tech Support. Though you may not believe you have anything connected that can use that much data, this isn't necessarily the case. When you create the new topic, telling us what you have connected to your modem will help to know where to look. You can see your currently and past connected devices, since the HughesNet modem was last plugged in, here.
