Hi therE! My name is lauran and I'm looking to find how to use my 3G with AT&T to travel. I'm in the US and we are going to china. The international plans looked so expensive and doing a search, I found ppl buy a card in china and cut it down. Do I have to turn anything off on my computer before I do this so I don't get any roaming charges? Does the roaming apply only apps and Internet? Basically I want to use the iPad for my downloaded movies, music, games and take pics to upload online, and check email and news, weather on Internet. If I wait to buy a card in hong kong, is it also good in gilan and Beijing? What about when I'm on the plane over there, what will I have access to? I've been burned beforenwhen I had Verizon with my Droid and they wanted to charge me 300 dollars when I had my phone in Mexico and I barely accessed the Internet or my games I downloaded. The games I downloaded needed the Internet. I'm notnsure if my games I downloaded here need Internet as well so I'm not sure if I can use on the plane. How do I buy a card in china? Are there particular stores that sell them? Do I have to cut it? If so what tools do I need. Sorry lots of questions and very confused but want to make the most out of my iPad. Thanks!
