Hi!, You can try this few simple steps:

1) Go to Settings, switch Notifications to Off.
2) Inside Settings, go to General and switch Location Services to Off.
3) Inside Settings, go to Mail, Contacts, Calendars, switch Fetch New Data to Off.
4) For extra safety when you have access to Wifi, go to setting and switch Airplane Mode to On if you just want to surf the net. Please be aware that you won't be able to receive call with this mode On. Remember to switch it Off after you're done with the net.

See if this will help you...
