If you updated your PC to Windows 10, you can see how much data you spent in the past 30 days by clicking on internet icon and going to Internet settings and Data usage. For me it's 109GB since I updated to windows 10
These are apps that used the most data

Don't know don't know

But I used all my mobile data like I do every month & it's so annoying

lemme check.

337.88 MB

I only used 470 mb on my phone. Wtf is going on

Well in the past month I've used 108.24GB I thought it was because of watching TV shows but I think it's actually just ATRL

Jesus christ

From the 3rd of August to the 14th I used 146GB

I've been downloading a lot and I rewatched all of PLL so I guess that's probably why.

So far this month i've used 11.45gb but last month i only used 13.31gb , ow and this is on mobile

How do I find this out on an iPhone? My phone doesn't have the T-Mobile app.

settings > cellular > and it'll say "cellular data usage" somewhere

I've used 22GB on my phone this month
