I'm going to Bangkok with 2 friends. I'm reading many old threads about AT&T charges, roaming and international data plans and want to make sure I'm understanding things right. If I go in airplane mode, I will be able to text, surf the web (go on Facebook) and use apps on available free wifi but I won't be able to receive or make phone calls correct? Also saw that they had data pkgs you can buy like 50MB or 20 MB - is that still available and would there be additional charges if I did that? Bottom line, I don't care if I can't make or receive calls in airplane mode if that's all I have to do to avoid any extra charges as long as I can still text, surf and use my apps. Is that possible?
