Nokia N8
Net usage billing when not in use

I have installed WhatsApp, Puppy Talk, Devil's Ride and OVI maps from nokia ovi store. After that every day my mobile report an net useage without using any application and got billed with a message like the following

"Calla charges from bsnlnet.mnc072.mcc404.gprs for 630 min 0 sec for used volume 57.69 kilobytes are Rs.0.12". I am not using any application at night and even after that in the morning i get message like this. Please help me to rectify if any settings are wrong or so.

Thanks and regards
