My wife has just got a Samsung Monte on Virgin and would like to know how we can turn off the 3G internet as will be using our home Wi-Fi and she wont want to use it when out as we dont get a internet bundle with Virgin and dont want to get a big bill.

If you are not using the internet and the 3G icon is on the home screen are you downloading anything from the internet?

There must be a way to turn it off I have looked at the online booklet on Samsung website but can see how to turn it off.
