I'm leaving in the morning for London/UK countryside on business. Will be traveling with my iPhone. I can either turn everything off and rely on wifi only (and not have a phone while I'm there), or I guess I can call ATT and have them turn on international roam for a week... 
Can anyone fill me in on what I should expect if I choose to do that, what it covers, etc?
Alternatively, can I get a prepaid sim over there and use it for phone and have phone/wifi only (no data)?
