Malaysia, Singapore, and China? I'm traveling for a few weeks to do some work, and I'll be in Australia, Malaysia, Singapore, and China. I have no idea what my options for service are, except what AT&T told me, and I'd eat shards of glass before I'd pay those rates. Can I get a temporary sim card for my phone in those places? Any idea how much it will cost? Can I get it for voice only, or do I have to get voice & data together? Any tips are appreciated. Even links to resources would be helpful. Thanks in advance.
