Hello, I'm Aziza from Azerbaijan. I have a problem with my new samsung galaxy sl telephone. Whenever i use package data( for example, for facebook), more charges apply than it should be. I mean there're lots of applications which require internet connection, and whenever i open package data, these apps begin to use package data, and additional charges are applied. I would be happy if somebody explains how to stop these apps to use package data. Thanks beforehand. Have a nice day))))
