Well few days passed I have bought my new Nokia E7. While setting up the email/ internet I am unsure whether my Nokia E7 is using the Wifi connection or the mobile network connection for data transmission. My Nokia E7 does not does not automatically connect to my home network. It seems that my E7 is default connect to the mobile network using up all data allowance and needs to be manually connected to home network even after it wakes from sleep. Please help me, I want it to default connect to the Wifi, also ask before connecting via the phone network to avoid unwanted usage.
