Because the data doesn't cost anything different than when I'm at home. Do you always do that when you're at home too? That's very conscientious of you, I can tell you that my data bill is already under $5-10/mo most months, there is just WiFi everywhere so I don't always go to the trouble. The fact is that the calling rates are very reasonable by default while traveling abroad, and there are no extras charged for data or text. I rarely travel internationally, but not to be held back by my phone! There are no special travel packages to buy, it just works wherever you go.
