I think Asia may be a little more progressive in having data access on regular prepaid sim cards.
I had a regular AIS sim card in Thailand that had data access. Not BB services, but regular data. So I was able to use it, although just to test it out since I had wifi. Charged by time and not data quantity so a good deal for smartphones. They also have data oriented sim cards with better data plans but still with call capabilities. Dtac and the 3rd provider are similar.
I also had a sim card in the Philippines (Globe) that had data access, and I think one in Hong Kong (SmarTone?) as well.
