where can I see the consumption of my data?

[Chou30]

I've received a text message from O2 telling me that I have almost used up all my data for the month....after logging into my account, it looks like I have used 7.3GB out of 8GB in 5 days....now I'm working from home and mostly use home wifi.  Is there a way I can see how the data was consumed?  I know I can see it on my bill at the end of the month, but I'm just 5 days into my new billing period and would have to wait until 24th Feb to see the usage.  Thanks......!

I know you can see it from your phone what is your data usage. Will show you what apps have been using your mobile data over a period.
