Sorry, I don't understand. Here's the situation: at home or the office, you can use wi-fi for Internet access, obviously. Then when you travel outside the wi-fi range, you should already have your 3G and cellular data options clicked (in your Settings menu). Right? If so, and you're still having problems, try resetting your network. It's all in the General Settings area. Get back with results.

You understand me correctly. For using 3G I need to restart my phone everytime . The service provider ( Airtel) says that setting is okay as it is working after restarting . I have also tried by turning wifi off. But 3G works only after restarting of phone
