To reduce the cost of data via the mobile phone network to zero, all automatic synchronizations must be prevented. In all the e-mail server can be set manually only when the Microsoft / Hotmail servers you have to instead take the synchronization check for eg e-mail (on page 920 lumens that are with finger between the pages settings and applications from side to push forth under the heading of e-mail accounts, and then Microsoft is to set. In Data Sense can also the pages with finger from side to side slide to see on what program as much via WLAN or mobile has used data). There are other applications that you shut yourself loads and thus not part of the core system, as listed under Settings, such as Nokia trailer where the advertising information is automatically updated for movies or immediately when you call the application, which can only leave by the application uninstalled.
In my case I had a hardware reset (settings Info reset), so delete everything and start over again to prevent the phone approximately every two hours connects to the data network and the day about well over 1 MB Data on baseless charge you consumed, though at the same time also WiFi was on. I guess the location, which runs in the background now wasted still a day up to 1 MB of data, these switches are best off or goes offline, that means on the data connection under Settings Mobile, on the one hand to get in navigating GPS but on the other hand, the unwanted sending of position data via Internet prevented. Otherwise you should turn off in general settings under the mobile data connection when you do not need data network, but just want to make calls or use wireless. Unfortunately, there is no way in the search button to prevent the image of Bing over about 125 KB, instead one can equal access to Internet Explorer To work around this.
By using the application folder, a shortcut to airplane mode, Wi-Fi, Bluetooth, mobile settings, positioning or location, etc. can be realized.
