I have found this page is pretty good for finding sim card info:

As I do not see calling a lot of people in country, the data for maps and local info is important to me, and you can get a AYC call international plan for only 13.99/mo through skype if calling is important.

Will be heading down first 2 weeks in Sept and am looking forward to it.
