Samsung Galaxy Y S5260 sucking data even when idle

[OldWine]

Even in idle mode with packet data uses ON mode, my phone sucking data so much that its sucking all my data-pack and eroding my main talking balance even within 2/3 hours! Please help.

Under Settings, there should be something to do with data. You should be able to see a data meter there, which will show you how much each app has used.
