I've got the new £25 goodybag (20gb already gone :'( ) I've just seen the message about all your full speed data being used and it still says 9gb. Easy fix and not a massive problem. I've took a screenshot but don't know how to add it....
To add the screen shot.
Go to your original post bottom left click 3 dots will open then click advanced reply then you'll see a camera click on that.
Then press on middle of Grey screen you'll see files or photos to choose select and it will load.
