when I log into MyOptus account online for my prepaid mobile broadband (which i use for my iPad) it says 'View detailed usage' but it only shows usage for that day, and there is no option to view or search for anything else.
I want to see usage for the month - and no, I don't want to look at it on the App!!
The data usage via the my account portal is the worst in the industry in my opinion. It once displayed hourly usage and previous
days months however all that is gone for me. If you are using prepaid MBB I don't think the app does anything even if you wanted to use it.
Edit: Not to mentions it's that slow I often give up waiting for the account portal to load. You have to click view details and then then usage details amount to see previous days. These links may be hidden in mobile view so switching to desktop view may help.
