Just another thought whiston. Upload and download will eat into your data allowance. I am on an unlimited data package so have not thought about it until I read your question. You will probably be sharing date in the background with windows ( which whilst being updated regularly, being new, may be considerable). You may want to again go to settings, Privacy, Feedback and Diagnostics, Then the Diagnostic and Usage panel. You can change this default setting to basic although Microsoft recommend full. This will cut your usage.
