That's a pretty high amount of data usage. If I wasn't downloading so many Linux ISOs, just streaming YouTube, etc only use 200-300GB a month at most. That amount of upload is extremely high, it's even more of a red flag than the download amount. I think either you have a device that's hacked and being used as part of a botnet or else your device's statistics are wrong.
