I'll be going to the Philippines in December for 3 weeks, I know that AT&T's international data rates are ridiculously expensive, what is the best way to still be able to use my phone over there? Ideally, I'd love to still be able to make calls, text and use data, but I realize all that may be asking for too much. So what options do I have? Could I turn data and phone off and still text there? How about jailbreaking and maybe buying their disposable SIM cards over there to use?
