I am also having the same issue. From time to an alert box with data usage details are displayed. This message comes from service provider ( BSNL, Airtel etc). When I leave the phone idle some time there are too many such pop ups. I have to press OK button so many times before starting to use the phone or apps. It is annoying. It also turns on the the screen frequently after turning off the screen. This results in unwanted batter usage.
How to turn of the notifications from Airtel or BSNL ?
How to tell android to suppress those pop-ups?
How to tell android not to turn on the screen for these annoying pop-ups?
I find the android settings tab to be too simple and rigid. It doesn't give me the necessary configuration options.
