How do I turn off the data on my LG 620G?

I am going out of the country on vacation. How do I turn off the data on my LG620G

I did call them but they said, it was not necessary because the phone I have is not roaming. I questioned that answer because a friend said she got charges a lot of money for data received while in Italy. Thank You, for your information

Hi Jacqueline. Just contact your carrier and request that your data be disabled. When you come back to Canada, just call again to have it enabled.
