If you are using Windows 10 there are a few steps that need to be done on Satellite internet to reduce data usage.
1) Turn Live Tiles Off for all your apps and in the settings (Microsoft has step by step guide if you google "How to turn Live Tiles off" you should see the links).
2) If you use iCloud app that runs in the background make sure that only Contacts and Bookmarks are selected on your UI (can be accessed by right clicking on the iCloud icon in your Hidden Icons area of taskbar). NOTE: in the Bookmarks section do NOT have a check mark in Internet Explorer. There is a known glitch that can cause it to use up to 2 gigs an hour- Chrome and Mozilla don't have the issue.
3) It is better to have a Wi-Fi connection through a router so in the Windows settings you can set it to a "Metered Connection". This way Windows it self tries to minimize any background apps from using up extra data. Walmart has many routers that work great with Exede.
4) On a "Metered Connection" set Windows Updates to let you decide when to install (Windows on a metered connection won't automatically check for updates so remember to check manually every once in a while (use your free zone- if you have one, or wait till before your data reset and update on that date monthly).
Hope this helps some.
