How to set my iphone to travel to Canada

[wilbmeister]

I am leaving for Canada tomorrow and I don't want to have to pay crazy data costs. I know if I make a phone call I will pay my roaming amount but is there a setting I should set the phone to so I don't use the Edge network for any data roaming? Also, if I am connected via wi-fi will I pay to use the internet, email, etc?

Thanks!

Turn "Data Roaming" off to avoid using the cellular data network with roaming charges. This is in Settings: General: Network.
